What rating should I practice after seeing this?
By siddhantchimankar, history, 2 years ago, In English

Hi guys, I'm new to CF. I try to give all the Div 2, 3, 4 contests but have managed to only become pupil till now. I was trying to analyze my profile using this tool : Codeforces Analyzer : Link and saw something strange.

In my first 5 contests I have performed really well, 2 contests have performance rating around 1800, 2 have around 1500 and one has around 1600 but the next 5 contests after that, I have performed poorly with an average performance rating of around 1200.

Because of this I was practicing questions of problem rating 1200 for some while. But now I'm confused, what do these rating show and what is my actual level and most importantly what problem rating should I be practicing?

Thanks.

The performance calculation in that website is wrong for the first $$$6$$$ contests, because it doesn't consider the new rules for rating calculation.

You could try to find the performance formula (it's not difficult). Then, you can calculate the performance in the first contests by replacing the displayed ratings with the actual ratings.

    Okay thanks. So I make that I should be practicing 1300, 1400 level problems at the moment right?

      I'm not a huge fan of practicing on codeforces (the recent problems are quite adhoc and it's not easy to actually learn something from them, the older problems are more useful but some of them are quite bad). I recommend USACO Guide.

      Of course, that's subjective. Since there are a lot of blogs asking for advice on Codeforces, I would also recommend reading some of them and trying the strategy that fits you best.

    Yeah, if you (siddhantchimankar) wanna see your actual performances I recommend the carrot extension

In my opinion, you will solve 1200-1300 tasks faster if you participate in contests. So forget and solve 1400-1600

Your actual performance:

It's quite not bad for someone new to cf, i would recommend you doing VC's (virtual contests) of latest contests if you want to perform better and solving problems of range 1600-1800. But actually doesn't exist secret formula of best problems to practice, what I did was just open a problem and solve it, independent from it's rating (obviously those weren't 800-1300 rated problems, but sometimes I met very interesting even 1400-rated problem, which also were "yusful").

    Hey, but while practicing I notice that a lot of times i'm not able to do even 1300 problems, like 30, 40 percent of time, so would it be wise to practice 1600-1800 problems?

      Well, then lower difficulty — practice 1200-1400 problems, or as the comment bellow noticed, combine easy and hard problems.

      And don't forget to do vc's, that's my personal advice ;)
