GCSE prep that already knows where the gaps are
Adaptive GCSE Maths and English Language practice for Years 10 and 11 — paced by the FocusPlan engine, with indicative 9-1 grade feedback on practice mocks. More subjects coming.
GCSE Maths and English Language prep for Years 10-11 — adaptive practice and mocks with indicative 9-1 grades, paced by the engine that already knows them.
What you get
- GCSE Maths and English Language practice — Questions built around the 9-1 courses your child is taught in Years 10 and 11. Maths covers number through to statistics; English Language covers reading, creative writing, transactional writing and language analysis. More subjects are on the way.
- Revision paced by FocusPlan, not panic — FocusPlan decides what to practise next based on where the marks are weakest — so your child just opens the app and works on what actually moves their grade. No revision list to build, no topic lottery.
- Practice mocks with an indicative 9-1 grade — Timed GCSE-style mocks return an indicative 9-1 grade and a breakdown of where marks were lost. Indicative means a guide to where your child stands today — not an official predicted grade, not a school forecast.
- GCSE prep starts from years of evidence — If your child grew up on GrammarPrep, the engine already knows exactly where their gaps are. GCSE prep starts from years of evidence, not a blank page — every strength and gap the engine has mapped carries forward.

How it works
- Set up or carry over your child's profile — If your child practised with us through KS3 or earlier, their profile carries straight into GCSE — no setup needed. Starting fresh in Year 10 or 11? Tell us their year group and the engine runs a placement to find their level.
- The engine targets the weakest marks first — FocusPlan identifies which GCSE topics are costing the most marks and sequences practice to address them. For children who grew up on GrammarPrep, this is instant — years of data already show exactly where to focus.
- Daily adaptive practice — no revision plan to build — Each session is a focused set of questions at precisely the right level — challenging without overwhelming, short enough to be sustainable through Years 10 and 11. The parent dashboard shows progress by topic and grade band over time.
- Mock exams with indicative 9-1 feedback — As the real exams approach, timed GCSE-style mocks give your child experience of exam conditions and return an indicative 9-1 grade with a topic-by-topic breakdown. These are practice guides — not official predicted grades, not school forecasts.
Grew up on GrammarPrep? GCSE is where it pays off.
If your child prepared with us for the 11+ or kept practice ticking over through KS3, the same profile carries straight into GCSE — every strength and gap the engine has mapped keeps working. New here? You can start at any stage.
Frequently asked questions
Which year groups is Frettle GCSE designed for?
Years 10 and 11. The engine adjusts pacing based on how much time is left before the exam series — Year 10 has more runway to build foundations; Year 11 shifts towards exam-pace practice and mocks.
Which GCSE subjects does GrammarPrep cover?
Right now, Frettle GCSE covers Maths and English Language — the two subjects every sixth form, apprenticeship and employer looks at first. More subjects are on the way. If a subject you need isn't listed yet, you can register and we'll notify you when it launches.
Are the 9-1 grades official?
No — they are indicative only. Our practice mocks return a 9-1 grade band to give your child a sense of where they stand today, based on how they answer timed mock questions. Official predicted grades come from your child's school; official results come from the exam board (AQA, Edexcel, OCR etc.) after the real exams.
How does the adaptive engine work at GCSE level?
The FocusPlan adaptive engine tracks performance on every question — accuracy, time taken, and the kinds of mistakes your child makes. At GCSE it works out which exam topics are secure, which are weak, and which are completely untouched, then puts practice time where it will lift the grade most. For children who have been on GrammarPrep since primary school, it also knows the long-term patterns — where they have always struggled and where they tend to fade under pressure.
My child grew up on GrammarPrep — is the data actually carried forward?
Yes. One profile spans every stage. The engine that knew your child at 10 still knows them at 13 and at 15. Every strength, every gap, every topic where they have historically needed more time — all of it carries into GCSE prep. For families starting fresh at GCSE, the engine builds the same picture from scratch over the first few sessions.
How much does it cost, and is there a free trial?
GrammarPrep starts at under 66p a day on an annual plan — a typical £40 one-hour tutor session costs as much as 60 days of GrammarPrep. Every new account gets a 7-day free trial, no card required. We'll email you on day 5 so you can decide before anything is charged. Every paid plan also includes a 14-day money-back guarantee.
How does Frettle GCSE compare to a private tutor?
A skilled tutor brings conversation, motivation and in-the-moment insight that software can't replicate. What GrammarPrep adds is unlimited practice volume at any hour, precise topic-level tracking, and a cost that's a fraction of one-to-one tutoring. Many Year 10 and 11 families use both — a tutor for the human side, GrammarPrep for daily reinforcement and mock practice between sessions.
My child is in Year 10 — is it too early to be thinking about mocks?
It's never too early for low-stakes practice mocks — especially in Year 10, when there's still time to act on the feedback. A Year 10 indicative grade isn't a prediction of the final result; it's a diagnostic that shows where the syllabus gaps are while there are still 12–18 months to close them. The families who find Year 11 least stressful are often the ones who started practice mocks early.
