Free Revision Resources - FAQs
Last updated April 2026
Are these study notes really free?
Yes. Every chapter on thinka.ai is free to read, with no signup or paywall. The AI practice questions, instant auto-marking, and progress tracking live inside the thinka app, which is also free to start with sample questions each day.
Which exam boards and curricula are covered?
thinka supports Key Stage foundations, GCSE and A-Level pathways alongside Cambridge IGCSE & A-Level, Pearson Edexcel IGCSE & A-Level, Oxford AQA IGCSE & A-Level, IB Diploma Programme, junior secondary and primary programmes.
How do I turn these notes into exam practice?
Open any chapter on thinka.ai, scroll to the bottom, and tap the practice CTA. The thinka app generates unique exam-style questions on the same topic and auto-marks your answers with detailed feedback. No two practice sets are ever identical.
Can teachers use these resources with their classes?
Yes. Teachers can share chapter links directly with students, then assign matching AI-generated worksheets through the thinka teacher dashboard. Marking and progress tracking happen automatically.
How are the notes kept up to date?
thinka monitors official syllabus updates from each board (HKEAA, Cambridge, Pearson, Oxford AQA, IBO) and refreshes affected chapter notes when specifications change. Each chapter shows a 'Last updated' marker.
