How hard is it to become red in CF
By solvemproblr, history, 5 years ago, In English

Hi!

I'm just university freshman and I've been doing cp for 2-3 years. I'm planning to spend my upcoming 3-4 years for learning cp. My current goal for this period is to reach grandmaster. From one side, for me it seems it's somehow possible, by working hard and also considering I've 3-4 years, but from the other side we can see so many people struggling in orange or purple for many years and also considering I'm not good at math and I don't have special skills.

So I want to ask you how hard is it to become red? Is it somehow possible for me or do I need to change my goal? Also it would be perfect if you (I mean red guys) shared your stories on making red(how much time did it take, how hard it was, etc.).

Thanks in advance)

P.S I'm not asking about how to become red because it's asked before in so many blogs, I'm asking about how hard is it to become red.

    Hi
    Yes I need to practice to become better, but I'm not asking how to be red, I want to know how hard it is or how much time does it take.
    And also wait, are you bot, my blog got 9 downvotes in 5 mins, whille yours get 7 :thonk:

      Like I first said, all the grandmasters will say: "it will take a lot of time, as one needs much practice"

      and FYI I'm not a bot :)

    When you say 3-4K hard problems, do you mean hard for your current level or hard at whichever level you were at the time ?

    For example, when you were $$$1500$$$ a problem rated more than $$$1700$$$ might have been hard :)

      3K problems hard != 3K hard problems

      Reading comprehension is also important :)

        Nah, that sentence doesn't even make sense. You're not gonna become orange if you solve thousands of div 2 A or B. That's why using the number of problems as a metric is foolish. Look at how people went full ratism and downvoted ghoshsai5000 for asking a sincere question here. That's disgusting.

          Almost all people (who are not fool ofc) know that it's not possible to achieve it by solving thousands of easy problems and TripleM5da didn't say if you solve 3K-4K problems you will be grandmaster, he just said he got it in this way. Also personally I didn't take this comment seriously because it was more likely written for motivating.

          But I'm agree about ratism thing

          Actually you kind of can what I meant was imagine taking time to solve 3K-4K problems averagely your level that's how tough it is. It might be less hard for people with better education thou, since I never went to school and started practicing from college. But you can kind of factor in that time in your education too.

            I would prefer something like an estimation of number of hours spent practicing but it's still fair if you mentioned "averagely your level" in your initial comment.

          Number of problems is just thrown around as a metric because it's easy to measure -- just go to a bunch of online judges and sum up how many problems you solved.

          I believe my count was easily over a thousand when I got red as well, though since I solved contests that necessarily includes several easy ones. As long as you aren't specifically looking for easy problems to inflate your count I think it's a reasonable stat since it's hard to know if a problem is at the right level before solving it.

Just stop taking this too seriously. From what you mention you seem to be thinking about whether it is possible for you to get red, but i think that is not important. What you should think of is how you can get good instead. Also, I see a lot of people that get very focused on one thing and cannot do it good. Btw, maybe you should have a hobby or interest, for example, listen to our songs :) You can avoid your brain always working in the same way, and thus acting like a robot, which is bad because CP is about creativity.

    I believe, the question "how hard it is to become red" is quite similar to "how hard it is to become a millionaire". Yes, hard. But the biggest difficulty here is not the hard work. Count (approximately) how many people aimed to do this are as determined as you are (or more), count the probable percentile you'll get into (taking into account talent, teachers, parents, age, work etc.) and count how many grandmasters+ there are and cry. You may train the hardest but still not be the best. Even more subjective opinion (and controversial, probably) is, 2400 is the kind of a cutoff, where the hard work only won't usually pass because there are lots of hardworking people but competitive programming is competitive. I don't think just being a grandmaster is the best aim also, it's mainly about being fast and efficient in 2 hours. You can be an experienced coder, a walking algorithm library, a program architect, a mathematician, a teacher, etc. There are tons of directions to follow, make sure you won't regret doing competitive programming all your best years.

      Well, I'm not doing cp to be experienced coder. If I wanted that, I would just learn some algorithms and focus on work. I'm doing competitive programming because I need this competition, it's ok if I can't be the best. It's ok If I stay at the same level after 3-4 years, I won't regret. For me it's much better than practicing for being program architect, mathematician, teacher...

Though this may be cruel, existing results shows that your personal features matters a lot. For some who are gifted, reaching GM could be much easier. There are LGMs who are very young, while there are also who have devoted their whole time to competitive programming and still struggles at a certain level. Becoming someone with extremely high rating is desirable, but what is more important is that you enjoyed the process of learning and competing. Wish you good luck!

      I think you should abandon the idea of being "good" or "bad" at math, or anything similar. There probably is some notion of innate talent, but I think people can go much further than they realize with deliberate effort.

      This always works handy as an excuse. It is very reassuring to think that people doing well in competitive programming are doing well because they have talent or gift or whatever.

    I assume those young guys, that have reached LGM are not just gifted, but they spend much more time practicing than others, also probably they have better way to do that, as I know that you can spend your time uselessly while practicing, for example it's easier with a teacher.

      Yes, you are right. For example, djq_cpp, the 14-year old LGM, is from Nanjing Foreign Language School in Nanjing in Jiangsu Province, the school is one of the best schools in China in OI, and Jiangsu Province is one of the provinces where many students study for Olympiad in Informatics, many of them in order to get into better universities. They have very intense and systematical training in schools and students typically start at a very young age, with many starting in primary school.

      I was once a contestant from Jiangsu Province, and competed with students there. I also went to prestigious schools for training, so I know a little about it.

        Can I read about it somewhere in more detail? I'm now curious, because my knowledge matches what never_giveup said — there are no such schools in my region (Ukraine, Russia, Poland etc.), unless we have very different views on what "intense and systematical training" means (based on how strong Chinese contestants are, I wouldn't think so).

If you achieve a 2100 rating, then you have 15% chance of becoming a red.

If you achieve a 1800 rating, then you have 33% chance of becoming a 2100 rating with just time and practice.

If you become 2100 rating then tried hard to become red for 2 years and failed, then It's impossible to become red unless you find one magical pill. There are only 7 of them. Each of them can be used exactly one time. It's unknown how many out of 7 is not used yet. So, GOOD LUCK.

Here is the truth.

+140 iq and yes It's f**k**g related to this.

strong math, technical aptitude.

extensive training for at least one year.

but for the inspiration part. Man, it is unnecessary to become red, just become expert.

    I believe, everyone can improve a LOT more than we expect or think. IQ doesn't matter that much. Mostly, people who say they can't improve because of low IQ, I have noticed that the problem doesn't seem to be their IQ or anything, the problem is that they think they work hard a lot whereas actually they didn't practice much. For example, they might say that they solved 100 Div2A/2B, why are they still specialist/pupil. It is because solving 100 Div2A/B is not the end, but the beginning of competitive programming. I_love_Tanya_Romanova at one point studied 20 hours/15 hours PER DAY!! I don't think most people give that much dedicated time per week, as much he was once giving in A DAY, so clearly he is a very strong coder.

      While I agree with the overall idea of the comment above, I should add that the context I'm mentioned there is highly misleading: I've never done consistent training/preparation at the "15+ hours per day" level, and I don't even think it is sustainable. Moreover, trying to do something like that would most likely be counterproductive, and dangerous to your physical and mental health.

      I do believe that I would've performed significantly better if I've practiced more :)

    I guess it's not just about math, it's about mathematical thinking, you learn math and stuff, but you may never use math formulas while solving problems, but if you know math you solve particular problems faster or just solve.

    But idk this maybe wrong, cuz I'm not good at math...

    Sometimes I observe even the opposite effect. People without strong CS background or language knowledge are gaining rating pretty fast because of being strong mathematicians. Of course by that I don't mean being PhD at Calculus or Linear algebra but being good at mathematical olympiad and/or discrete maths problems because it assumes you have a strong analytical mind in discrete structures, good math induction, etc.

    Take an IOI list and an IMO list and count similarities.

I think the question should be "how much time am I willing to spend?" instead of "how hard is it to become red?", and the time needed isn't trivial. For me, during the weeks before I got red, I spent at least 1-2 (sometimes up to 6 ish) hours per day solving problems that I wasn't able to solve from some contest or other.

Just click on your handle, then choose "magic", then you can become red in seconds.
