How to become Candidate Master
By PR_0202, 4 years ago, In English

Hi,

From the previous 5 months I gave about 40+ contest and I am still stucked at Expert everytime I hit 1800+ rating it falls down again and again....

Please suggest me some strategy to become a Candidate Master on CF.

Thanks in advance...

UPD 1: Finally after 7 weeks of this blog I became CM :)

many of my friends were asking for suggestion. so, here are the few of them.!

  1. Errichto, Aman Dhattarwal and Love Babbar (in hindi) playlist if you want to step into CP or you're a beginner.
  2. If you want to be rated X, then you must be able to solve problem with rating X+200. And try to solve every problem within a short time as you're in competing.
  3. Whenever giving a contest, don't care about falling of your rating, your aim should be to solve as many problems as possible, it really helped me to improve my performance in the contest.
  4. Up-solving (Atleast problems till 2000 rating).
  5. Try finding weak areas and start solving those problems.
  6. Try to make friends who are having rating +(100-200) of your current rating and who gives contests frequently.
  7. Most important Don't Give Up.

UPD 2: After continuous grinding of about 7 months of last update I finally became Orange :)

    For becoming Expert on CF I would suggest do 10 random 1600+ questions per day ans see the result in a month :)

    And never miss any contest..(must)

      Why don't you apply the same with little change(solve 1900+).

        Solving random topics won't help much in my case ig.

        You must have sufficient practice in each topics..

          Not really, that works for CM as well in my experience. There aren't really many "topics" that appear below 1900 (or 2100 for that matter). There might be a few such ideas but you'll mostly likely come across them while solving problems.

            In fact, That's work till GM

            I never learn any particular "topics". Just randomly solve problems with 2100-2800 difficulty

      if you never mind, please tell me how you managed time to solve 10 1600 rated problems in a day. what is your approach to solve a problem? how many time do you give per problem? I am asking because I can't manage to solve 3 problems(1500 rated) a day. I spend about 2-2.50 hours per problem. what will be more efficient as your opinion ?

        Don't jump directly to 1600 just solve problems with your rating+200 then you will see the result. Every day make sure that you are doing better than the day before.

      10 random problems 1600+ questions what the heck? When I practice 2200 problems, each problem can take me 2 hours(if I still have ideas). Lets say if I am 100% concentrated, 1 hour or I read an editorial. I cannot have 100% concentration for 10 in a day basically.

          Everybody I know has alt accounts. There shouldn't be a restriction for anyone taking part in a contest from secondary account as long as he is not cheating. The reason for a rule against such wouldn't be an ethical one, but might be a technical one. It makes sense that people taking part in contests from alt accounts might disrupt the rating system. But nonetheless, it is inevitable that there would be some inaccuracies in the rating system. A rule that can't be applied is one that shouldn't be tried in the first place.

          Regardless, that's not my question

You should try:

  1. Upsolving(Atleast problems till 2000 rating).

  2. Try finding weak areas and start solving those problems.(Like for me its generally implementation.)

  3. Try to make friends who are having rating +(100-200) of your current rating and who gives contests frequently.

  4. You can give older(unattempted) virtual contests.

I have not downvoted your blog, but are you really surprised about downvotes? Just google 'how to become Candidate Master codeforces' and you will get at least 5 similar blogs. I don't see the point of making a new blog on a googleable question.

About your question: solving Div2D consistently should be enough to cross 1900.

See I will tell you what I did, or to say what changes I made in my practice strategy to become a candidate master.
You can see my graph, initially after giving 80+(which is double than yours) contest, I was not able to cross even 1800, but then in the last 3 — 4 months I changed the way I used to practice, and you can clearly see the result.
1) First of all, always solve the problems which are always at least 100 or 200 higher in rating you are aiming for. In your case practice problems in the range of (1900 — 2100).
2) Try to learn new techniques, Like in the past 3 months I read about treaps, hld(heavy light decomposition) in trees, centroid decomposition, game theory, etc. This will give you confidence and will keep you motivated (At least it helped me).
3) Whenever giving a contest, don't care about falling of your rating, your aim should be to solve as many problems as possible, it really helped me to improve my performance in the contest.
4) Enjoy solving problems.
Try this practicing strategy, and Hope to see you become a candidate master very soon :).
Sorry for my poor English.

    you don't need anything mention in number (2)

    problems involving HLD, treaps, centroid is easily 2500++ which is not required to reach CM (i never solve those kind problems in live contest)

    Thanks for your comment . I have 2 fake accounts with more than 80 contests (48 + 25 + 29) and the 3 are in cm. I've been following those tips for a few months now and I don't feel much progress. I learn slightly more advanced topics, I train with 1 or 2 daily problems from 2000 — 2200 to stay in shape, but I have become even slower to solve problems A, B, C div2 (the goal is to solve all 3 in less than 25 minutes) try D in half an hour and E in one hour. but I do not meet the times. What would you recommend me?

    Sorry for my poor English. xd

    To this, I would like to add something.

    I try to solve problems on my own, and If I fail to do so and read the editorial, I write it down the whole editorial on a paper as my punishment (No matter how small part I missed initially). Doing this forces me to think a little more before giving up :P

In practice dont waste time on problem with rating below certain lvl (like ur maybe 1900... I prefer try to push that lvl to 2000, 2100 ... some topics like game theory can be exception but for rest u have to follow that strict lvl)... U cant be CM with practicing below 1900 only, as general ur rating = Lvl of questions u practice — 200.

PS: I tried solving lots of virtual Contests, solving lots of problems of my rating +-200 even sometimes +300 or +400. I solved random problems + topic-wise also, still not able to improve.

For those writing shits about the line in which I mentioned love babbar and Aman Dhattarwal, I would suggest them to read the line again.

" ...if you want to step into CP or you're a beginner "

This is totally based on my experience, I personally watched their videos in the starting to learn c++ and have some basic understanding of it.

Most of the beginners jump to Codeforces directly without any implementation stills and can't even solve A. You must know about basic things like time complexity and loops.

Again I'm saying it's my opinion, and I mentioned those points because some of you had asked for it, if you have any problem just dislike the blog.

    You're right about that part, but I think the problem lies in their other videos like in which they make it seem a great deal to be 5* on codechef, and say that this will directly help you in cracking coding rounds. It's really misguiding for beginners who assume that rating is everything. Specially when they themselves have no proper CP background, such guidance has no weight. That's probably the main reason why people are complaining.

            It’s just his opinion He is only stating the resources he found useful. If you find something better, use that instead of questioning others about the credibility of the resources they have used.

      Take part in a contest and get a bad rank(1k+ is enough).

      Tomorrow morning, you'll find you're purple.

      P.S.Don't get a too bad rank, or you'll drop to blue.

I have been struggling for making Master for a year. After I retired at 2017, I really don’t have enough time and motivation to actively dedicate to CP. However, I have been always thinking I am in the master level, it is not that hard even if I dropped to Blue.

Then I jump from Blue to Yellow with like 4 contests, so please keep confident always.

I have seen many people struck in expert range for a long time. What is the mistake they have done which can be avoided? Or reason is experts to cm tack time for more knowledge and practice?

    There's no secret trick, you will be stuck in some range it's just that less talented people reach this point in specialist-CM range while more gifted ones rush to M-GM and get stuck there. There's no secret, it's just about practice and your potential.

    It sucks to hesr but there is certainly a huge genetic potential role in terms of mental capabilities, there are many people who test different strategies for 4-5 years yet fail to reach Master or higher, whereas some fresh coders rush to Master in a smaller timeframe e. g. 10-12 months.

    Were it possible for everyone to reach LGM with sufficient amounts of practice you wouldn't see hundreds of coders stuck at GM-IGM for 5-6 years. They can't be insane to practice the wrong way which gets you to 2500-2700 but not beyond. We all know it is not likely for someone to practice easy problems or not expand their thinking ability and rech 2500 rating, you have to be doing something right.

    Just don't overthink it, try your best and enjoy the journey.

I wonder why you didn't receive the rage from the lower-ranked users unlike me.

Have you gave up competitive programing? Because I don't see submissions for the last year
