Contest math - books, problem sets, videos, etc..

[Heisenberg7]

Hello,

I am looking for contest math books, problem sets, videos, etc. I'm quite good at algebra, but I'm not so good at geometry, counting, probability and number theory. I know a few resources such as aops, AMC, AIME, local competitions and a few books. It would be great if you could suggest me a few more books or resources so I can choose problems that are up to my level.

Cheers

Was never into contest math nor care for it. But for Trigonometry,

I recall students may use Loney Trigonometry.

What level are you at relative to the AoPS introductory geometry, number theory, and counting& probability books? They're a good place to start

I am using those at the moment. I suppose I am on their level, but I am looking for something to upgrade to after completing the intermediate versions.
