Top 10 Topics That Decide a GCSE Maths Grade 7-9 (Higher Tier)

A grade 7 took 146 marks out of 240 on Edexcel and a grade 9 took 208. The ten Higher tier topics that close that gap, in the order to do them.

You are sitting on a grade 6, you work hard, and the score will not move. That is one of the most common places to get stuck in GCSE maths, and the way out depends on a number most students in it have never looked up.

I am Aadam, and I have been tutoring GCSE students at School House Learning Centre since 2020. What follows is the ten Higher tier topics that hold grade 6 students back, what examiners want on each, and the order to attack them in. First, though, the number.

Grade 7 and grade 9 are different targets

Most advice treats grade 7 to 9 as one band. The mark boundaries say otherwise. These are last summer's Higher tier boundaries. AQA, Edexcel and Eduqas mark the qualification out of 240, and OCR out of 300.

Board Grade 7 Grade 8 Grade 9
AQA 166 192 219
Edexcel 146 177 208
Eduqas 116 150 185
OCR 170 217 264

Look at the Edexcel row. A grade 7 took 146 out of 240, which is 61%. You can drop 94 marks across three papers and still get a 7. A grade 9 took 208, which is 87%, and leaves you 32 marks of room in the whole qualification.

Those are not the same target and they do not need the same work.

Grade 7 is a reliability problem. At 61% you do not need the hardest questions on the paper at all. You need to stop losing marks on things you already know, finish the questions you start, and pick up the middle of the paper cleanly. Most grade 6 students who want a 7 are losing far more marks to arithmetic slips and unfinished multi step questions than to vectors.

Grade 9 is a coverage problem. At 87% there is nowhere left to hide. Every topic below has to be automatic, and the last few marks come from the questions almost nobody finishes.

Work out which one you are actually aiming at, because it changes the plan. Look up your own board and year in our GCSE grade boundaries tool, and how many marks you need on Higher tier sets out the full scale.

Grade 7 and grade 9 are separate summits, and the second climb is the longer one

Your 2027 exam dates

GCSE maths sits on the shared JCQ timetable, so these dates apply to every board and both tiers.

Paper Date
Paper 1, no calculator Friday 14 May 2027
Paper 2, calculator Thursday 27 May 2027
Paper 3, calculator Monday 14 June 2027

All three are morning sessions of 1 hour 30 minutes.

There are thirteen days between Paper 1 and Paper 2, and another eighteen before Paper 3. For a student chasing grade 8 or 9 that month is worth more than any block earlier in the year, because you can spend it on calculator topics only, with two papers still to sit. Trigonometry with the sine and cosine rules, compound measures, and anything involving heavy arithmetic all live there.

You are also given a formulae sheet in the exam. Ofqual confirmed it for the 2025, 2026 and 2027 series, and the Higher version carries more than the Foundation one. Read it in your first minute rather than assuming what is on it, and check which formulae it leaves you to remember, because that list is the one worth drilling.

Where the marks actually are

Edexcel publishes the split of marks by topic area at Higher tier, and the other boards sit close to it.

Topic area Share of the marks
Algebra 27 to 33%
Ratio, proportion and rates of change 17 to 23%
Geometry and measures 17 to 23%
Number 12 to 18%
Statistics and probability 12 to 18%

Algebra is the biggest single block on a Higher paper, by a distance. That is worth holding onto while you read the ten topics below, because algebra is also the thing that quietly limits students in topics that look like geometry or probability. A vector proof is algebra. A probability question ending in an equation is algebra. If your algebraic manipulation is slow, it costs you marks in places that are not labelled algebra.

As for why the top end questions are hard, it is rarely the content itself. It is four things.

  • They combine topics, so one question might use Pythagoras to find a length, trigonometry to find an angle and then a volume formula on the result.
  • Each step depends on the last, so there is no way to answer part c without getting part a right first.
  • The context is unfamiliar, which tests whether you understand the method or only recognise the layout of questions you have seen.
  • One slip early carries all the way through, so precision matters more here than anywhere else on the paper.

A grade 8 or 9 question usually braids three familiar topics into one problem rather than testing anything new.

Topic 1: Trigonometry and Pythagoras

Why it matters. Geometry and measures is 17% to 23% of the paper, and trigonometry is the largest recurring slice of it. It also turns up inside questions that are labelled as something else, which is what makes it expensive to be shaky on.

What you need fluently: Pythagoras and trigonometry applied in 3D shapes, including the diagonal of a cuboid and the angle between a line and a plane; two applications of the same rule in succession; combining a length calculation with a volume; the sine rule, the cosine rule and the area formula for non right angled triangles; and bearings combined with trigonometry.

A typical question gives you a pyramid with a square base of side 8cm and a perpendicular height of 12cm and asks for the angle the slant edge makes with the base. You have to spot the right triangle, use Pythagoras for the slant height, then use trigonometry for the angle. Three steps, and the marks are spread across them.

How to fix it. These questions often bury a volume or surface area calculation inside the trigonometry, and students lose the marks on the 3D formulae rather than on the trig itself. If that sounds familiar, our Area, Perimeter and Volume Mastery Bundle covers prisms, cylinders and surface area properly before you layer trigonometry on top. Check your working with the Pythagoras calculator and the trigonometry calculator, which picks sin, cos or tan for you and says why. Then work 20 to 30 past paper questions on multi step and 3D applications from our free exam resources or Physics and Maths Tutor.

Topic 2: Quadratics

Why it matters. Quadratics sit inside the biggest mark block on the paper and are rarely labelled. You meet them hidden in a geometry problem, in a probability question, or in a graph sketch that you need in order to answer something else.

What you need fluently: solving by factorising, by completing the square and by formula, and knowing which to reach for; sketching a quadratic with its roots, turning point and y intercept; finding the equation from key points; simultaneous equations where one is linear and one quadratic; and what the discriminant tells you about the roots.

A rectangle of length (x+3) and width (x-1) with area 35cm² is the standard shape of it. Set up the equation, expand, rearrange to zero, solve, then choose the answer that makes sense as a length. That last step is a real mark and it is thrown away constantly.

How to fix it. This is a volume topic, so practise in quantity rather than depth. The quadratic equation calculator checks the discriminant before it solves anything, and the completing the square calculator reads the turning point straight off the finished form, so both are useful for marking your own work. For the linear and quadratic pair, the linear and quadratic simultaneous equations calculator shows the substitution line by line and draws where the line crosses the curve. Then work through every quadratics topic in order on Maths Genie, starting with factorising and finishing with graph sketching.

One early slip in a long question knocks over every step after it

Topic 3: Circle theorems

Why it matters. Circle theorem questions are written to sort students. Knowing the theorems gets you a mark or two. Spotting which one applies in a diagram with two tangents, a chord and an overlapping triangle is the actual test.

The seven you need are the angle at the centre being twice the angle at the circumference, angles in the same segment being equal, the angle in a semicircle being 90 degrees, opposite angles in a cyclic quadrilateral summing to 180 degrees, a tangent meeting a radius at right angles, two tangents from a point being equal in length, and the alternate segment theorem.

The grade 8 and 9 versions chain three or four of them together to reach one missing angle, and expect the reason written next to each step.

How to fix it. Practise identifying the theorem before you calculate anything. Go through a set of diagrams and write only the name of the theorem that applies, no working. That diagnostic step is the one grade 6 students skip, and it is the difference between knowing the seven and being able to use them. Flashcards with a clear diagram on each work well here, and Dr Frost Maths has interactive sets that build from single theorems to combined ones.

Topic 4: Algebraic fractions

Why it matters. Algebra is 27% to 33% of the paper and algebraic fractions are where it stops being mechanical. Students who cannot handle them meet a ceiling around grade 6 regardless of how much else they know.

What you need fluently: simplifying by factorising and cancelling; adding and subtracting with unlike denominators; multiplying and dividing; solving equations containing them; and rearranging a formula where the subject appears twice, or sits inside a root or a fraction.

Solving 3/(x+2) + 2/(x-1) = 1 is the standard example. Common denominator, multiply through, expand, collect, solve the quadratic that falls out. Five steps, each of which can end the question.

How to fix it. Start below the topic rather than inside it. Almost every student who struggles here is still slow on numeric fractions or on collecting and multiplying terms, and no amount of practice at the top fixes a gap underneath. Our Fractions Mastery Bundle and Algebra Mastery Bundle rebuild those two layers properly. They are deliberately below grade 9 content, which is the point. Once they are automatic, go back to algebraic fractions and the topic gets much smaller. When you do, the algebraic fractions calculator simplifies, combines and solves them with every step shown, so you can find the exact step where your working went wrong.

Topic 5: Compound measures

Why it matters. Ratio, proportion and rates of change is 17% to 23% of the paper, and compound measures live inside it. They appear on every series and combine easily with other topics, which makes them a favourite for the harder questions.

What you need fluently: speed, density and pressure with every rearrangement; unit conversions including km/h to m/s and g/cm³ to kg/m³; compound measures combined with the volume of a prism, cylinder or sphere; direct and inverse proportion including their graphs; and exponential growth and decay.

A cylinder of radius 5cm and height 20cm filled with liquid of density 1.2g/cm³, asked for the mass in kilograms, is the typical shape. Volume, then mass, then a unit conversion. Most lost marks in this topic are in the conversion rather than the formula.

How to fix it. Drill the unit conversions on their own until they are automatic, separately from the questions they appear in. The reasoning underneath all of this is the same scaling skill tested at Foundation in a harder costume, so if the scaling step is what keeps failing rather than the formula, our Ratio and Proportion Mastery Bundle is the faster fix. Then practise density combined with volume of prisms, cylinders and spheres specifically, because that pairing turns up far more often than chance would suggest.

Topic 6: Vectors

Why it matters. Vectors are almost entirely top band content. When they appear they are aimed at grade 7 and above, and a student who avoids them concedes 8 to 10 marks before the paper starts.

What you need fluently: column and lettered notation; adding, subtracting and scalar multiplication both geometrically and algebraically; magnitude via Pythagoras; position and displacement vectors; and using vectors to prove that lines are parallel, that a point is a midpoint, or that three points are collinear.

A parallelogram OABC with M the midpoint of OA and N dividing BC in the ratio 2:1, asked to prove OMN is a straight line, is the classic. Express both in terms of the base vectors, show one is a scalar multiple of the other, say so in a sentence.

How to fix it. Vectors are conceptually unlike anything else at GCSE, so build the basics properly before touching proof. The proofs themselves need precise notation that is genuinely hard to self mark, which is the case for getting them looked at by someone else. Our Mock Exam Marking Service starts at £39.99 per paper and marks to exam board standard. 1st Class Maths has vector booklets that build in the right order.

Topic 7: Graphs of functions

Why it matters. At this level you are expected to recognise cubic, reciprocal, exponential and trigonometric graphs on sight and know how they behave, rather than plot them point by point.

What you need fluently: recognising the graph type from the equation; sketching the right shape with its key features; finding an equation from a graph; translations, reflections and stretches; using a sketch to solve an equation; reading distance time and velocity time graphs; gradient of a curve at a point; and area under a curve.

Sketch y=2x³-3 and y=2x+1 on the same axes, then use them to find approximate solutions to 2x³-2x-4=0. The step being tested is realising the intersections are the solutions, not the sketching.

How to fix it. Build a single reference sheet with the characteristic shape of each function type, then practise sketching straight from the equation without plotting. Plot points only when you are checking yourself. The transformations are worth separate drilling because they are cheap marks and are forgotten faster than anything else on this list. To check the solutions you read off a sketch, the cubic equation calculator solves the cubic itself and draws the curve, so you can see how close your estimates were.

Topic 8: Probability trees and Venn diagrams

Why it matters. Probability at the top end stops being about probability. It becomes tree diagrams without replacement, Venn diagrams carrying algebraic unknowns, and conditional probability, all of which end in an equation.

What you need fluently: trees with and without replacement; conditional probability; Venn diagrams including three sets and algebraic expressions; independent against dependent events; mutually exclusive events; frequency trees; and reading probability from two way tables.

A bag with x red balls and 2x blue balls, two taken without replacement, probability both red equal to 1/6, find x. Draw the tree, write the expression, form the equation, solve, then check the answer makes sense as a number of balls.

How to fix it. The probability is usually the easy half. The marks go on forming and rearranging the equation at the end, which is an algebra skill wearing a probability hat. If that is the step that keeps breaking, Forming and Solving Equations drills exactly it, and the Probability Bundle covers the tree and multiple event work underneath. Always sanity check at the end, since probabilities have to sit between 0 and 1 and branches have to sum to 1.

Topic 9: Proof and reasoning

Why it matters. Proof questions test whether you can explain, not just calculate, and they are increasingly attached to other topics rather than sitting on their own.

What you need fluently: algebraic proof using 2n and 2n+1 for even and odd; geometric proof using circle theorems, angle facts and congruence; proof by exhaustion; counter examples; and the difference between showing something must be true and showing it could be true.

"Prove that the sum of any three consecutive integers is always divisible by 3" is the shape. Let them be n, n+1 and n+2, sum to 3n+3, factorise to 3(n+1), then say in words that this is a multiple of 3. The final sentence is a mark.

How to fix it. Write proofs in full sentences. "Since", "therefore" and "which is a multiple of" should appear in your working. Examiners award the conclusion separately from the algebra, and students who stop at 3(n+1) lose it every time. Read your own proof back and ask whether someone who had not seen the question would follow it.

Topic 10: Sine and cosine rules

Why it matters. The sine rule, cosine rule and the ½absinC area formula are almost exclusively top band content, and choosing between them is a skill of its own.

What you need fluently: the sine rule and when it applies; the cosine rule and when it applies; the area formula for any triangle; finding angles with inverse functions; and using all of it in 2D and 3D contexts alongside Pythagoras and basic trigonometry.

A triangle with sides 7cm and 9cm and an included angle of 65 degrees, asked for the area and the third side, needs the area formula and then the cosine rule from the same setup.

How to fix it. Build a decision rule and practise applying it before you calculate. Right angle present means Pythagoras or basic trig. No right angle with a matching side and opposite angle means the sine rule. No right angle with two sides and the angle between them means the cosine rule. The sine and cosine rule calculator chooses the rule from what you already know, which is exactly where these questions are usually lost.

How to work through the ten

Knowing the list changes nothing without an order. This is the sequence I use with students targeting the top grades.

  1. Week 1, find out where the marks are actually going. Sit a full Higher paper under timed conditions and mark it against the scheme. For every mark lost, write down whether the cause was method, arithmetic, misreading or time. Rank the ten topics above by how many marks each one cost you.
  2. Weeks 2 to 16, one topic a week, weakest first. Watch or read the method, work 15 to 20 questions rising in difficulty, then attempt 5 questions from real papers aimed at the top band, and rewrite every wrong answer from scratch rather than reading the solution and nodding.
  3. Weeks 17 to 24, mixed questions only. These topics have to connect before they are worth anything, so work questions that pull two or three of them into one problem. This is where grade 8 and 9 marks live.
  4. Weeks 25 onwards, whole papers twice a week. Set your target from your own board's boundaries rather than a national rule of thumb. On Edexcel last summer a grade 7 was 146 out of 240, so about 49 marks a paper, and a grade 9 was 208, so about 69 a paper. On AQA both numbers are noticeably higher. Working to the wrong target either flatters you or crushes you.
  5. Every four to six weeks, get a paper marked by someone else. Self marking is generous in exactly the places that cost you at this level, particularly notation in proofs and unstated reasons in circle theorems.

One honest caveat on the diagnostic in step 1. If it shows the losses are coming from the layer below these ten topics, fix that layer first. A grade 6 student who is slow on fractions or ratio gains more from closing those than from grinding circle theorems, and our Maths Mastery Lessons cover that layer one skill at a time. Track the topics from struggling to confident as you go, which is what the SHLC revision planner is for.

Sit a paper and rank the topics by how many marks each one cost you, then work the list in that order.

What keeps students at grade 6

  1. Revising what already works. Practising a topic you are good at is comfortable and produces almost no new marks. The uncomfortable topics are where the grade is.
  2. Learning topics in isolation. Mastering quadratics separately from graphs, separately from simultaneous equations, leaves you unready for the question that uses all three, which is the only kind that appears at the top.
  3. Practising methods rather than choices. At this level the test is usually which method applies, not whether you can execute it. That skill only comes from unfamiliar questions.
  4. Not doing enough whole papers. Topic sheets tell you whether you know a method. Only a full paper tells you whether you can find the method under time pressure with five other questions still to do.
  5. Starting in March. Moving from a 6 to an 8 is roughly six to nine months of systematic work. Starting after the mocks leaves you doing the volume without the time for any of it to settle.

For parents

Three things are worth knowing.

The jump from 6 to 9 is bigger than it sounds. Aiming at a 7 first and treating 8 or 9 as what comes after is more realistic than treating the band as one target, and it is far better for morale.

Progress at this level shows up in the process before it shows up in the score. A week spent on circle theorems can leave the paper mark flat and still be the reason it jumps a month later. Marking their paper yourself is not the useful contribution. Asking them which four causes their lost marks fell into is.

Watch the workload. Chasing the top grades pulls students into long evenings, and sleep lost is progress lost.

Common questions

How many marks do you need for a grade 9 in GCSE maths?

In June 2026 a grade 9 on Higher took 219 out of 240 with AQA, 208 out of 240 with Edexcel, 185 out of 240 with Eduqas and 264 out of 300 with OCR. That is between 77% and 91% depending on the board, so check your own rather than working to a national figure.

How many marks do you need for a grade 7?

In June 2026 it was 166 out of 240 with AQA, 146 with Edexcel, 116 with Eduqas and 170 out of 300 with OCR. On Edexcel that is 61%, which means you can lose 94 marks across the three papers and still get a 7.

Which topics are hardest at GCSE Higher maths?

Vectors, circle theorems and algebraic fractions cause the most trouble, but the harder questions rarely test one topic. They combine two or three familiar ones and make each step depend on the last, which is why students who know every method separately can still stall at grade 6.

Can you get a grade 9 on Foundation tier?

No. Foundation reports grades 1 to 5, so grades 6 to 9 are only available on Higher. A student capable of a 7 or above has to be entered for Higher.

How long does it take to go from grade 6 to grade 8?

Around six to nine months of systematic work for most students, because it needs both new content and much higher accuracy on content you already have. The accuracy half is the part that cannot be rushed.

Is a formula sheet given in the Higher paper?

Yes. Ofqual confirmed a formulae sheet for the 2025, 2026 and 2027 exams, and the Higher version carries more than the Foundation one. It leaves plenty out, so check which formulae are missing and drill those.

How many past papers should I do?

Enough that an unseen paper stops feeling unfamiliar, which for most students aiming at the top band means a full paper or two a week from around February. The number matters less than what you do afterwards, and a paper you rewrite properly is worth three you tick and file.

When are the GCSE maths exams in 2027?

Paper 1 is on Friday 14 May 2027, Paper 2 on Thursday 27 May and Paper 3 on Monday 14 June, all mornings of 1 hour 30 minutes. The dates are identical across boards and tiers.

Sit a full paper this week, sort your lost marks into the four causes, and start with whichever of the ten topics cost you most. The list is only useful in that order.
