How to study for USACO, USNCO, & AMC 10?Answered
Hey! I鈥檓 a rising sophomore and I鈥檓 planning to take the USNCO exam (US National Chemistry Olympiad) in March 2023. I鈥檝e reached out the coordinators and will reach out to my chemistry teacher before the school year. How do I study for it? I know I need to buy textbooks and do practice problems like crazy, but are there any tips I鈥檓 missing?
I plan on doing USACO (USA Coding Olympiad) in my junior year because it starts in the winter and I don鈥檛 think I鈥檓 prepped enough for it this year. I鈥檓 building coding projects and doing Harvard CS50. Are there any tips or tricks for USACO?
I鈥檓 debating whether to do the AMC 10 because I checked the past year鈥檚 practice problems and they鈥檙e way out of my league. I want to pursue it, so how would I go about that. Any tips/tricks?
Thank you.

Yes yes yes to the textbooks (I鈥檇 argue those are the BEST resources for olympiads) and practice problems!
For AMC 10, I鈥檇 recommend The Art of Problem Solving Vol. 1 (or 2)! There are probably free pdf鈥檚 somewhere, but here鈥檚 a link:
AoPS also has a huge library of practice problems called Alcumus, where you can work on your weak areas. Also, I really love the Mathcounts Mini worksheets & videos鈥攖hey鈥檙e pretty much the foundation of my AMC abilities.
ALSO鈥攜ou might want to join some of the olympiad discord servers! will connect you to all of them.
I think that you are doing the right things to prepare for these exams. Like any test, the key to a high score is to simply spend a lot of time doing practice problems and understanding the skills you will be assessed on. has some more tips that will help you.
