I am a freshman in college.
Is there any advice for approaching undergraduate level math competitions despite a lack of extensive high school math competition experience? My participation in high school math competitions started to wane over the years, not reaching very far in the AMC and other regional competitions.
However, I was hoping to make more time for competitive math in college, but I feel (knowing I would not do so well in competitions such as the high school AMC, AIME, USAMO, etc.) that I would only get very lost just trying to look up past college competitions and making sense of the questions and answers. How should I approach catching up? Should I just start with these high school competitions, or is there another way? Any advice would help.
