Practice & exam prep

Practice questions Exam-style questions by syllabus point — mirrors real IB command terms and mark allocation. Pick a topic, or assemble a full timed paper from the bank. Topic summaries Compact, exam-focused revision sheets — formula, method, common exam pattern. Formula booklets The official IB formula booklet, plus reference documents. Past papers & examiner reports my school only Real IB and Cambridge papers, gated to a verified school email. Study planner Spaced retrieval — resurfaces weak topics before you forget them. Mastery tracking Exactly where you stand, topic by topic — not one vague overall score. That's what builds real exam confidence, not guesswork.

Real ideas from the library not placeholders

Geometry Is a Snail Shell Archimedean or Logarithmic? Measure a real shell, fit both spiral models, see which one actually wins. Optimisation Optimising Fences Fixed length of fencing, maximum enclosed area — the classic, done properly. Statistics Do Richer Countries Win More Olympic Medals? GDP per capita vs. medal count — correlation, and where it breaks down. Modelling The Freddo Index In 2000 a Freddo cost 10p. Track what it costs now, find the growth rule hiding in the wrapper. Probability Stuck at Deuce You win 60% of points on serve — how often does a deuce game actually go your way? Data collection Why Won't My Phone Charge the Last 20%? Collect your own phone's charging curve tonight, find the model hiding in it.

Enrichment

Science — "How Do We Know?" Mostly there A branching story of how we found the atom — every scene ends in a question worth chasing, asked by the scientist who first asked it. History of Maths Mostly there Same idea, for mathematics — from al-Khwarizmi's algebra to why zero needed its own symbol.

Interactive apps 53 tools Experimental Derivative tracer, Bayes' theorem, Voronoi builder, Argand diagrams and more — still being refined for pedagogical soundness, not fully polished yet. Activities 38, across 6 categories Worksheets, investigations, quizzes — and live games like Efron's Dice, no login needed to join. Timeline The mathematicians and scientists behind these stories, laid out in order.

For teachers — set work, keep track

This isn't a business — it doesn't need to make money. What it does need is to cover its own running costs: PDF generation, hosting, storage, and the AI credits behind the Coach and the dev team that builds this (that's Claude, in the interest of full disclosure).

Fair usage limits apply — nothing here is metered to squeeze you, just to cover what it costs to run.
