Combinatorics for AIME / ARML Prep

Hi: I am looking to get better at Combinatorics on the computational level (AMC / AIME / ARML). I think it's my weakest subject in Competition Math. Besides doing Brilliant problems, does anyone have any suggestions for learning and practicing Combinatorics? Like books and websites?

Hi, I suggest you participate in Proofathon. :)

Hey AK! I just saw you at States! Great job, by the way, in the Countdown round. I also just saw you while watching streaming of last year's Nationals! I was the tall guy with brown hair from Berkeley, the team that got 5th. Do you remember the host? He was stalling for, like, 50 minutes about his stupid honeymoon and architecture in Barcelona. So stupid. I wanted to ask you: how do you get so insane at math? I have a discussion for it, but if you could just give a couple of tips and resources, that would really help me when I try again next year. :D
