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?

Thanks in advance!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

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
