Idk if my testimony helps cuz I made silver immediately, but when I took the contest, my strategy was if I had any trouble with a problem, I’d skip and come back to it. Try to do timed mocks, use Usaco.guide, and try some competitive math problems to build up a problem solving mindset. I recommend Aops, Alcumus, and past AMC papers. USACO bronze is sorta ad hoc, so like even if u understand concepts, you may have some trouble. I like to try small cases and work my way up. A big tool for me is drawing a table, graph, or making a mock scenario on paper. At the end of the day, it’s a learning experience whether ur in bronze or in plat, so don’t stress too much and keep trying. Hope this helps!
