My Competitive Programming Journey (and how to practice)

Here's the stuff I mentioned in the video:
USACO: http://www.usaco.org/current/index.php
USACO Training: https://train.usaco.org/usacogate
Codeforces: https://codeforces.com
CodeChef: https://www.codechef.com
AtCoder: https://atcoder.jp
And a cool site that lets you see difficulties and stuff for AtCoder problems: https://kenkoooo.com/atcoder#/table/

This is a special video for reaching International Grandmaster on Codeforces. I'll probably do more of these for some sort of milestone special, so the best way to see more is to subscribe :)

By the way, we're hosting the Montgomery Blair Informatics Tournament on November 14! It will be much like the contests you're already used to, with problems authored by my school's programming team. Registration is open now, and you can see the competition's rules, format, past problems, and info for registration at https://mbit.mbhs.edu/
