I do USACO now, and I am preparing to take Bronze in January 2026(apparently not December 2025). This is a collection of all the problems I've done to improve my competitive programming skills. I did a class on USACO and some of these are the homework. There were 8 or 9 homework questions a week. Those homework qusetions were very hard for me. Dad helps me with the problems a bit(definitely not an understatement), and he always finds time for it somehow. I do USACO to prepare for Singapore's NoI, and possibly the IoI, so it's good it's a challenge. I have finished preparing for Bronze, and I am learning some Silver. https://usaco.org/ The website
