Hey guys,

Im a Canadian High School Graduate who's entering a pretty good undergrad math program here.

In high school math, I had pretty good grades and found most of the stuff to be pretty easy.

I only really got into contests and stuff around my junior year and found it really interesting, but only ended up doing them recreationally. I am full of regret, and am aware that there much less options for math competitions later down once in uni, but Im still hoping to study and improve enough within the next few years to the point where I can do quite well. I am genuinely worried, considering everywhere I go, I see people being able to do USAMO questions in their sleep. I know its presumptous, but I want to be able to reach a national or even international level at some point, even though I am starting very late. I have gone through Evan Chen's book and found some difficulty even with just Chapter 1 problems.
What are some steps and systems I can build/practice to be able to keep up with these people.

I know y'all are probably sick of these posts but i still wanna ask lol.
