Hi all 👋 I'm a physics and maths tutor, and over the past months I've built a free site for IB Physics and Maths AA/AI (SL & HL), focused on topical practice: - 📚 **Question bank:** ~4,500 Physics and ~8,000 Maths AA/AI questions, all original and written in IB style. You can filter by topic (A.1, B.3…), difficulty and skill (e.g. "graph interpretation", "show that", "multi-step calculations"). Each question has a full worked mark scheme. - 🧩 **Concept clusters:** long multi-part questions that take one concept (e.g. inclined plane, charged parallel plates) through a whole subtopic. One question revises the entire unit. - 📝 **Test builder:** pick topics and length and you get a printable test with a separate mark scheme in about 30 seconds. Handy for mock prep. - 🎯 **Diagnostic test:** about 15 minutes, shows which chapters are secure and which need work. - 🔬 **Simulations:** 180+ interactive Physics and Maths sims for the topics that are hard to picture (fields, SHM, waves, calculus…). - 🧮 **GDC guides:** exam mode and key sequences for your calculator. - ⚛️ **Physics extras:** equations you need that aren't in the data booklet, flashcards, and notes for every topic. - 🗓️ **Mock revision planner** for the weeks before mocks. I used AI to help draft questions at this scale, but every question is solved independently and checked before it goes up (the site explains how). ✅ Everything is free until 31 December, no account needed: examinerprep.com It's an independent site, not affiliated with or endorsed by the IBO, and these aren't past papers, so keep using your school's ones too. If you find a mistake or think something's missing, tell me 🙏 I'd rather fix it than have you learn it wrong.   submitted by   /u/AggravatingBed7135   to   r/IBO [link]   [comments]
