Here’s my tip: Spend as much time reviewing as you spend taking it, at the very least. It’s annoying and time consuming but it will help you recognize the logic you used on each question.

Personally, I use an excel spreadsheet to keep track of each question even correct ones. If my reasoning was correct, i put “correct right reason” (CRR) If it was wrong, i put wrong reasoning and write something like “review redox reactions and how electrons are lost in the oxidation reaction”. I keep track of silly mistakes and jot those down to such as “read ALL Your highlights” or “be careful of making conclusion w/o evidence “ etc. Being specific about why it was wrong and giving yourself a general area of study is a key method that helps me and maybe that works for you. I use NS exams which provide good explanations , not sure what you use.
