GCSE Maths guide

After the mocks: a calm 8-week plan

An independent guide for parents. NextJen isn't linked to or approved by any exam board, school or the Department for Education.

Once the mock papers come back, a short, steady plan often helps more than a big push. Here's one you can adapt.

When mock results come home, it's natural to want to do something straight away. Often the simplest plan is a few topics and a short routine that fits around school.

This guide sets out an 8-week plan for GCSE Maths in England, for the weeks after the Year 11 mocks. It's a starting point: shape it around what the school suggests.

Start with the marked papers

Before planning anything, look at the marked mock papers together, if the school shares them. Look for topics where marks were lost more than once, and for marks lost through missing working or running out of time. Our guide to what a Year 11 mock result means explains why the grade itself is only a guide.

GCSE Maths covers six areas, set nationally by the Department for Education: number; algebra; ratio, proportion and rates of change; geometry and measures; probability; and statistics (DfE subject content). Sorting lost marks into those six areas makes patterns easier to see.

Choose three topics, not thirty

A list of every weak topic can feel like too much. Ask your teenager to choose three topics to start with, ideally ones that came up more than once and that they nearly had. It often makes sense to start with topics that are nearly secure.

Write the three down where you'll both see them.

The 8 weeks

Many families find short sessions of 20 to 30 minutes, four or five days a week, easier to keep going than long weekend sessions. A simple shape:

  • Week 1: go through the mock papers, choose the first three topics and agree when practice happens.
  • Weeks 2 and 3: work on the first topic, then the second. Start each session with five minutes on something already secure.
  • Week 4: the third topic, plus one section of a non-calculator paper, untimed.
  • Week 5: a check-in. Which topics feel better? Swap in new ones where they do.
  • Weeks 6 and 7: the next topics, with a few mixed questions each session so earlier topics stay fresh.
  • Week 8: one full paper, timed, then mark it together and choose the topics for the next block.

If a week goes wrong, pick up where you left off. The plan is there to help, not to be kept perfectly.

Practise with the formulae sheet

Ofqual requires exam boards to give students a formulae and equations sheet in GCSE Maths exams, and students don't need to memorise the formulae on it. This started with the 2025 exams (Ofqual decisions, 2024), and in May 2026 Ofqual decided the sheets will stay for exams from 2028 onwards, for as long as the current GCSE Maths courses run (Ofqual decisions, 2026).

Find the sheet your teenager's exam board publishes and keep it beside them when they practise, so they know where everything is on the day. The sheet lists formulae. It doesn't say when to use them, so worked examples still matter.

Keep some practice calculator-free

GCSE Maths papers include questions without a calculator. For example, AQA's GCSE Maths is three papers of 1 hour 30 minutes each, and the first is sat without a calculator (AQA specification). Some calculator-free practice each week gives written methods regular use.

The summer exams usually run from May into June. For 2026, Ofqual's student guide gave the dates as 7 May to 23 June (Ofqual student guide). The school will share your teenager's own timetable when it's ready.

Keeping it calm at home

Agree the routine together, and let your teenager lead on which topics come first. Notice the effort and the routine more than the marks. Keep the talk about their own progress, not how friends or siblings are doing. If they seem stuck or worried, ask the maths teacher about support at school.

Practising with NextJen

NextJen's GCSE Maths practice fits this kind of plan. There are short lessons with worked examples and common mistakes, and practice questions come with typed answers and a worked method that uses the question's own numbers. Each practice paper shows the mark and an estimated grade, always labelled as an estimate.

You can try a question to see how the typed answers and worked steps feel, or see what's included in GCSE Maths. GCSE Maths on NextJen is £25 a month per student (£20 a month for founding families), paid monthly. You can cancel at any time and keep access to the end of the month you've paid for.

Questions parents ask

How long should each session be?

Most families find 20 to 30 minutes, four or five days a week, easier to keep up than long sessions. Short and regular is the aim.

Should we start with full past papers?

Usually not. Full papers are most useful once a few topics feel more secure. Start with topics, then add one timed paper near the end of the eight weeks.

Do students still need to learn formulae?

No, not the formulae on the sheet. Exam boards give students a formulae and equations sheet in GCSE Maths exams, and Ofqual decided in May 2026 that this continues from 2028 for as long as the current courses run. Students still need to know when and how to use each formula.

What if my teenager doesn't want a plan?

Let them choose the topics and the times. A plan they've shaped is often easier to stick to than one handed to them.
