Permutations and Combinations Resources? (1 Viewer)

I just saw the circle geo thread and thought it would be a good idea to post this. The only ones I can find online are really easy, much easier than any tests in actual exams. Does anyone have a good amount of hard permutations and combinations questions.

Buy a 2nd hand book....there are too many questions to do that it will be sure to take up your time. (if your own a lower budget I recommend searching up on Gumtree for books)

Plus there are enough exam papers floating around for you to work on.
