Saw a thread saying you should get IOs and IAs + EE done /somewhat outlined and easy to plug in to finish during the summer if ur junior going into senior year. Any tips on doing this? I took yr 11 HL chem and My teacher said we need to approve the topic with them before we begin… should I just find a generic topic on the internet and base my stuff a little off of that in the meantime? Also any resources u guys have in preparing for The IOs and IAs? Ex like the official criteria?
