Full access to all four courses, notes, flashcards & AI grading. Year 12 (DP1) only.
IB Math RevisionA dedicated practice platform for IB Diploma students taking Mathematics: Applications & Interpretation Higher Level. Attempt real exam-style questions across all five syllabus topics (plus HL extension material), get instant AI feedback on your written working, and watch your mastery grow — one confidence-weighted percentage point at a time.
Start Revising → How it works ↓Each syllabus topic has its own standalone practice engine. Questions are drawn randomly from a bank covering every sub-topic, presented one at a time — with worked reasoning behind every answer — so you actively build understanding of a specific weakness or work through all five topics in sequence.
SL content plus complex numbers, matrix algebra, systems of equations, and further sequence and series.
SL content plus composite & inverse functions, further modelling, and advanced graphical analysis.
SL content plus vectors, lines & planes in 3D, matrix transformations, and graph theory basics.
SL content plus Poisson & geometric distributions, expectation algebra, and hypothesis testing (chi-squared).
SL content plus partial differentiation, first-order differential equations, slope fields, and numerical methods.
Three things separate this from a generic problem set — and they're the same three things that separate a 6 from a 7 in the real exam.
Type your workings and Gemini AI compares them line-by-line against the official IB mark scheme. You see exactly where each method mark was earned, where the accuracy dropped, and what an examiner would have circled in red.
Try it →Every question hides a fully worked solution with method marks broken out, alternative approaches marked as accepted, and the accuracy tolerances that quietly decide grade boundaries.
Peek inside →Your topic mastery bar only fills once you've genuinely proved it — twenty questions per topic is the confidence threshold. No inflated 91%-after-three-questions nonsense.
Check my progress →Your final grade comes from three pieces: two calculator-assumed written papers sat at the end of Year 2, and a written investigation you complete during the course. Here's how the weighting breaks down — so your revision matches what actually earns marks.
120 minutes, GDC required. Short questions worth 5–9 marks each, drawn from anywhere across the five topics.
120 minutes, GDC required. Extended questions of 14–18 marks demanding modelling, interpretation and communication.
60 minutes, GDC required. Two longer problem-solving questions requiring extended reasoning and mathematical exploration.
A written investigation on a self-chosen mathematical topic. Marked internally, moderated by IB.
Every year I watch two students with the same ability get two different final grades. The gap almost always comes down to these four habits.
Advice that actually helped real students during their revision. All quotes are from students taking this exact course in the current academic year.
Paper 3 is essentially a 60-minute IA. Don't rush it — the marks are for exploration and justification, not just a final number.
Matrices come up more than you'd think. Get comfortable with matrix multiplication and inverses on your GDC — you don't need to do it by hand.
Graph theory is the friendliest HL topic. If you understand adjacency matrices and shortest-path algorithms, you're already at a solid 5.
Markov chains scared me until I realised it's just repeated matrix multiplication. Practise five of them and it becomes automatic.
€49 one-off · a full year of AI grading, mark schemes, and progress tracking · 7-day free trial to try before you buy · no auto-renewal, no surprises.
Start free trial →Any IB Diploma student sitting Mathematics: Applications & Interpretation at Higher Level for the May 2024 exam session onwards. HL AI is one of only two math courses (the other is HL AA) that lead to the "Mathematics HL" credit universities value most for STEM applications.
Pick a topic from the tiles above. A randomised question appears — attempt it on paper or on-screen. When you're ready, either reveal the worked mark scheme, or paste your workings in for Gemini to mark them against the official rubric. Whichever route you take, your marks are silently logged so your progress bars stay accurate.
No — sign in with any account (Google, Microsoft or email) and you get seven full days of everything, including AI marking and mark schemes. If you decide it's worth it after the trial, a one-time €49 payment gives you a full 12 months. There's no auto-renewal.
Regular percentage scores lie when you've only tried a few questions. If you get 3 out of 3 correct, that's technically 100% — but you clearly haven't proved mastery yet. This platform waits until you've attempted 30 questions in a topic before your bar can hit its true percentage. Below that, the bar shows a scaled-down "provisional" mastery — an honest picture of where you actually stand.
Because it's a single payment rather than a subscription, there's no auto-renewal to cancel. If you've paid and hit a genuine problem, click "Manage Subscription" once you're signed in — the two-button menu that appears will let you email pbromfield@ibmathrevision.com directly to sort it out.
