In Codeforces Round #604 (Div. 2) I was able to solve A,B and C problems and I received 1314 rating.

I have given total 3 contest on codeforces.

  • contest 1 — solved only A, rating — 1370 , rank — 5680
  • contest 2 — unable to solve any problem, rating — 1255 , rank — 4168
  • contest 3 — solved A,B and C, rating — 1314, rank — 2165

Despite solving more problems and getting better rank in contest 3 than in contest 1, why my ratings are less than that of contest 1 ? __

Rating is an accumulative metric of how well you're doing. You start at 1500 when you create your account. Your first contest resulted in -130 drop. Your third contest resulted in a +59 increase. Your rating change can be a metric of how well you did in a competition, not your rating's absolute value.

      its because of new rating system . your new account rating will be 1400 . but you will get that after finishing first 6 contest . ( in every contest in first 6 you will get some rating from 1400 )

      here is the detailed post about new rating system : link

          in your first 6 contest you will get some point ( which total sum id 1400 ) 500,350,250,150,100,50 (in total exactly 1400)

          you have to attend at least 6 contest to get that … ( you may loss or gain some more rating depends on your performance )

      It's because of the new rating system cf introduced. See [this].(https://codeforces.com/blog/entry/77890)

I think you need to solve 4-5 problems per raund. It depends on the number of problems and how many participants solved it.

    I think solving 4-5 questions in a round would make you candidate master

4 problems in 1-1.5 hour. 5 problems in 2 hours to become purple

To answer the literal question in the title, you can use the Virtual Rating Change Calculator to compute what would be the rating if you have the approximately same performance over something like 10 or 20 contests. (however there may be some bugs in the code — check out https://github.com/sjsakib/cfviz/issues)

Solving A,B and C below an hour should increase your rating, or at least wont lower it, however doing A,B,C and easy D is when you really climb. Also your rank is lower, because rank is acummulative, and before ranking you always start at 1500 rating
