5 C Problems for every day

If you can do that , You deserve to be 1700+ (given the problems are DIV 2 . C) , because as of now , I can barely do 4 or 3 C problems a day , despite doing them for 5+ hours

    The quantity doesn't really matter. If you solved 3 C problems but within 30 minutes each you would definitely do better than the person solving 5 problems in 3 hours each.

    Don't get me wrong. The person who who solves 5 C problems a day on their own definitely deserves it but it just doesn't happen right away.

    I do not think solving C so much would be good. I prefer to do virtual contests or solve the problems by yourself. Try and practice like you are doing the real contest. When you really can’t solve a problem, check the editorial and try to solve what you are capable to solve. After few times of doing this, you can improve a lot.

              You are just another all talk when it comes to doing something , I bet you are one of those people who ask how to become green/cyan any tips? I know your kind boy , those who are genuinely interested in cp and don't put up a show don't really care if they are green or grey , all they care about is solving problems

    No. You just didn't practice enough. I'm pretty sure that someone 1700+ loses lots of rating (closer to -100 than -0) if that someone doesn't solve C or solves it late into the contest.

    For you, problems ranging 1200-1400(don't train by letters, train by rating as letters is usually ranges a lot. Div 2 A can be as easy as a newbie and as hard as an international master difficulty(very rarely happens though)). If you are confident, move on. Otherwise, decrease the rating range. Training on too easy problems only improves your thinking speed. Which is good on CF so you can train a bit but don't waste time on it. But in some competitions such as IOI which is 3 problems for 5 hours, doesn't require fast thinking. Instead, it requires deep thinking.

    Well if you solve each and every problem with dedication , you can go upto expert

    They will increase your speed , so they are good for competing on codeforces , I can't comment about other platforms though .

Hey.I want to do the part 2 from it.Few questions.- - Is it possible to see the solve or tutorial if not succeeded? - After 10 days can my rating go upward if I follow every steps thoroughly? - What is the maximum time should I spend for a problem if my total coding schedule is 6hr/day.

thank you.

    This is a great idea, but I cannot implement it because I do not solve a lot of difficult C problems and also I can rarely solve D problems, So it will be difficult for me to choose problems.

        Hello, I don't know how to create mashups with A20J problems. I just know how to create mashups with CF problems only. You need to go to "gym -> mashups -> create new mashup"

        UPD: but maybe you will not be able to create a mashup if you haven't participate in enough number of contests. Try to google some information about CF mashups

I think we should choose the topic according to rating rather than the order.

Because the order is the relative difficulty in the competition, but not in the problem set.

For what sort of beginners? New comer to CF or to CP? See, if you've been keen on CP for years, it doesn't take long to reach Grandmaster even you just came to CF.
