Pupil to Specialist !!!
By srijon_32, history, 29 hours ago, In English

It took so long for me to become a pupil. How can I grow faster, and which topics must I cover as a pupil?

      1 Huge thing on CodeForces is speed. Make sure to sharpening your instinct and cutting edge thoughts about edge cases (I'm still getting trapped everyday and got slowed down... sadge)

        I'm also facing this problem. So many thoughts run on my mind while solving.

    I'm from Bangladesh. These contests  held at 8:35 p.m. in Bangladeshi time. So I've got no problem with my sleep schedule.

  1. https://mirror.codeforces.com/problemset?tags=1300-1700
  2. uncheck 'Show tags for unsolved problems'

solve problems of rating 1300-1500, try solving C of every div2 and upto D-E of div3 and stop solving those 800 rated now

    Ohh Thanks. Last few contests I solved C in div 2. But it isn't consistent.

there really arent any specific topics, you just have to solve div2 ABC decently fast, which usually doesnt require any advanced topics. sometimes graphs or trees show up at C, and rarely DP but generally, its just regular problems that dont require advanced techniques.

tldr: just solve more problems

If your goal is to reach specialist, there is no need to go topic hunting.

Just practice a lot of binary search problems learn basic math algorithms like sieve, mod arithmetic, gcd, divisors and prime factorization, understand basic bitwise operations. Basic dp would also help in some dic 2c and div3e problems, although not essential.

To sum up, just focus on your speed and practice greedy and basic math problems. Also I would suggest to focus more on div 3 and div 4 to gain speed and greedy problems intuition.

Is it possible to reach Expert with just solving A and B in div. 2 or div. 3? My first attempt in Codeforces long ago was very bad, but I’m thinking about coming back.

    Do tell please. Kinda hard stuck on 1200-1300, what rating range and topics should I practice to make the jump to specialist? Should I put more focus on speed or quality of problems? What strategies helped you?

Ig Binary Search on Answer and Variable Size Sliding Window is good to go for most of div 2Cs (currently strengthening them and I can notice better strike rate at 2Cs)
