Built from data. Not guesswork.
Every Edexcel A-level Maths paper from 2018–2026 has been catalogued question-by-question, alongside the specimen and sample papers. The Predictor weighs frequency, recovery (how long since a topic last appeared) and average marks to surface the topics you can't afford to skip.
Frequency-weighted
Topics that show up year after year get ranked first. The score adjusts as new papers drop.
Recovery-aware
Topics that haven't appeared in 2+ years climb the list. Edexcel cycles content — we track it.
Post-Paper 1 Mode
After your real P1, tick off what appeared. The Predictor instantly re-runs for P2. Unique to Pro.
How accurate is the model?
Back-tested against the real 2024, 2025 and 2026 A-level papers — using only data from before each exam.

How it works
- "Applied" = Statistics + Mechanics topics combined (Paper 3).
- Each prediction uses only data from years before the exam being predicted.
- Formula (Model M15): 40% frequency · 30% recency (exponential decay) · 30% avg marks/year · 10% overdue-gap bonus.
- Trained on every released Edexcel A-level paper (2018–2026) plus Sample & Specimen.

Honest answers
Is this just guessing?+
No. Every prediction is backed by the actual frequency of every topic across every Edexcel paper from 2018 to 2026. The scoring formula (Model M15) is transparent: 40% frequency, 30% recency (exponential decay), 30% average marks, and a 10% bonus for topics that are overdue based on their historical gap.
Why is Pure 'Paper 1 + Paper 2' combined?+
Edexcel doesn't reserve specific topics for P1 or P2 — they're drawn from the same pure pool. Any pure topic can appear on either paper. Predictor Pro adds Post-Paper 1 Mode: after you sit P1, tick off what appeared and the Predictor instantly re-ranks for P2.
Is the £29 really one-off?+
Yes. One payment, no subscription, no renewals. You get full Predictor Pro access until 7 days after your final exam. We'll never charge you again.
Does it work on my phone?+
Perfectly. Built mobile-first. Add it to your home screen and it opens fullscreen like a native app — no app store needed.
