Maybe div2 AB (difficulty 1100~1300) is enough. You can join in virtual contests and try to solve them.

      Everyone's journey is different. A lot of people practice on different platforms before joining Codeforces. Some have a decent programming/math background so they don't need to solve a lot of easy problems.

Start Solving 1400.

"Shoot for the Moon, even if you miss, u will land among the stars." — was my motto and I reached pupil just by solving 1300-1400. While doing 1300-1400, u will automatically become good at solving 1000-1200.

Your hit-map is very Well but You have to solve more standard problems like 1000 to 1300 rated problems.This makes you more confident.

  1. solving A and B in div 2 is enough to become pupil.
  2. For that I will recommend you to solve problems of rating 1200-1300. Generally A is most of the time pretty straight forward and for B it require some little observation which you can practice on these 1200-1300 rating problem.
  3. The topics you need are mostly: greedy, number theory,sortings,binary search (basic), pref sum (basic and very rare).

stop solving 800's.. start solving 1200,1300,1400 learn bit manipulation, dp, binary search, some number theory related to modular arithmetic, also start exploring standard greedy algorithms.

you need to do AB div2 fast, 5 div4 problems and 4 div3 problems. The E div4s and D div3s were usually 1400.

      Just simple algorithms like greedy, binary search, sortings

4 things

  • Stop solving 800s immediately
  • Start doing 1000....try to do a 50 of those
  • move on to 1100(50)
  • After that do like 100 questions of 1200 Do 100 of every difficulty from 1200

Don't stress about ratings... It's like that saying "You have the right to work but not to the fruits of the work, if it chooses you good, if not keep trying"

Keep in mind that one of the mistake that most beginner has is that they find it interesting to do bunch of easy problems but try to avoid strange topics or harder problems. Obviously if you want something, you have pay for it. So try harder and do more complex problems. My recommendation is not just for reaching pupil but higher ranking as well.
