This is an incomplete set of lists that I am creating for GCSE and A-level students who want to find resources to improve their problem solving skills. Feel free to bookmark this page (with today's date to compare to last updated) and come back to it regularly to see any changes.
I would highly recommend checking the relevant sections of the Art of Problem Solving Forums that you feel just a little uncomfortable doing.
You can find my GCSE problem-solving recommendations here.
You can find my A-level problem-solving recommendations here. If you want resources a little more directly related to admissions tests, look at my list here.
