my advice is to practice and read solutions after 30 minutes to an hour of thinking if you get stuck, increasing the level slowly, and read articles online on what you are solving if you want extra knowledge.

If you get stuck on a problem, set it aside for a moment and come back to it later.

As a USACO Gold competitor, think of binary search as a series of 0s(invalid answers) followed by a series of 1s(valid answers). This advice gave me a lot of insight when learning binary search.

      Codeforces has tags :), I'd recommend that you start from 1100 and progress up by solving 3 in each level until you can't solve without editorial. Then, use the advice above "to practice and read solutions after 30 to an hour of thinking". Good luck!

      I often just practice USACO problems and CSES problems.
