Welcome all suggestions for improving training!
Good luck everyone!
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
+1
I have selected 50 problems easy from type C.
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.
Nope , virtuals just don't suit me ... Don't get me wrong but I believe everyone have a different style to progress and yours is quite impressive ...
Ignore this comment. IDK how i offended someone. Anyways sry
I genuinely can't understand what's there to laugh about his username
Your color explains your useless comment tho
And even though I'm a pupil I can clearly see why you are grey
Rating : 844 lol , how low can somebody get i wonder
even if i get -3k rating but i will never stop doing cp. CP=interest
Lol
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
ok :(
continue the fight 🍿
Greenian vs grey fight. Haven't seen one for a long time.
I have nothing to say. He kinda makes sense. I'm just a newbie. lol
And he is just a pupil lol. Doesn't mean he has a higher rating thank you, so he is better than you.
Imo, it definitely should be $$$gray$$$ because US spelling is better than all other spellings.
Shaming someone based on his rating is an incredibly cowardly move
But when I was blue,I can do 3-4 div.2D in 3 hours.
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.
GoOd Initiative, But why not B's Edit: Thanks!!
I just want to ask the experienced coders, Is it effective to gain cyan if I follow this training very well?
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.
Thanks.
You're welcome!
Is it effective to gain cyan if I follow this training very well?
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 .
Thanks. I will try to solve as much as possible.
What should a guy like me do given that I can't give more than 15-20 hours a week?So, solving 5 C's everyday is just out of question.
50 problems C is a very easy problems, and The second part of the training is only 10 days, and not always.
Well, I guess I will give it a try. I am randomly solving C and D anyway including upsolving from contests:) and I think I have solved enough B's and A's for now.
Thanks a lot for this list. Will you make one for medium-level programmers also? Like maybe a mix of hard Cs and Ds. Would be very helpful to a lot of people I'm sure, including myself.
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.
Ah well. Thanks anyway!
What to do if I already solved most of the problems? :(
I think then you would know better than we do what you should be doing :)
you are a red Wild_Hamster, you are need is a list of 100 problems (F) from Div 1.
/rwhoosh
Does anyone have a list of good problems in the range 1500-1800?
You can use this one too.
Are these questions latest ones?
they are updated every second :) .
this is ontime site
the information will be fetched when you request to site.
Nice site. The only issue I feel it doesn't mark the problems already solved by me
Are you sure that you logged in ?
UPD : it doesn't show your solved problems
May be you dont need to do that much hard work for selecting problems.. You can find categorized problems, sorted by difficulty in A2oj .
5 problems a day sounds impossible
I am chose 50 easy problems C that anyone could solve +5 per day.
Sounds impossible for anyone at school(but accessible for one's who failed university entrance exam lol).
I solve A2OJ ladders for practice and I have already solved, won't say all, but a good bunch of C questions. I am still Cyan :)
Where am I going wrong? Pls help.
Started solving them.After a month i will be solving 250 problems. Thanks for making this ladder.
why do not you create a mashup for that.
Okay, I did it (created a mashup for the first two days). Here is a link to a group with mashups: https://mirror.codeforces.com/group/zMOq8sIMJT
Nice , your work is appreciated !!
Hello, can you tell me how to create these mashups please? I did your Day 3 mashup, and now I want to make some daily A20J mashups,I am a n00b sorry.
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
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.
I have solved 50 Problem A's and I could do them quickly
Should I move to problem B or complete the rest of A's list
move
Thank you so much
very helpful, thanks :)
Thanks for the list :)

thank you brother
Thank you sir...
I've selected to go with 1 A problem,3 B problems, and 2 C problems every day.
This is very helpful for me.
