How to train (I am parroting what Colin says in his video):

• don't burn yourself out
• practice in a challenging, but fun way
• value learning essential topics to your rating, over everything else
• there are many optional topics, like game theory. You can freely decide if you want to learn them or do other stuff
• solve random problems around and above your rating (between 0 and 500 ABOVE your rating)
• try to improve your skill rather than your rating and don't get discouraged by short-term fluctuations. Skill changes take month to be seen in your rating-graph
• roadmaps don't work because they are not personalized. But feel free to use them to build your own plan.
• Mix stuff up and make sure you don't force yourself into doing stuff you hate
• don't learn useless algorithms. Rather go solve random problems

Learning sources (this is my list, feel free to use or discard parts of it):

• https://neetcode.io/roadmap (its a leetcode roadmap. What I love about this are the explanation videos. They are 10/10)
• https://acodedaily.com/ (my default place of finding random problems)
• https://clist.by/ (the site I am using to find upcoming contests. Codeforces/Leetcode/Atcoder/Codechef is what I prefer)
• https://kenkoooo.com/atcoder/#/table/ (A list to find Atcoder problems)
• https://cp-algorithms.com/navigation.html (a lot of good algorithmic explanations)

You can do it bro.. just keep up the good work :D

It took me seven months to achieve it since I the first time I reached Specialist, so be patient and continue to train

and i want to reach pupil x(

Orkhan is a Turkish name. Are you Syrian or Turkish ?

Keep up the hard work !!

just practice more and more and more .......

If you only want to be an Expert:

In codeforces,speed is very important.Performance between accepted 3 problems fast and accepted 3 problems slowly sometimes may very huge.So you can try to do some more exercises on problem of 1400-1800 in 30 minutes.

If you want to improve higher:

I think you'd better stop learning useless algorithms,learn how to use binary search,dp and a lot of useful algorithms.

I also want the same .Lets us see who achieves it faster .

i want to reach specialist what should i do

study hard in the group

Thanks forr every body ..the all give me nice advises thanks for all

You shouldn't cheat

keep going and you ll be expert or even cmaster

I just participated in contests and solved one of the problems that I could not solve during the contest (maybe with help of editorial)

I explained some basic topics on my YouTube channel (in Arabic), check this link for example. They will help you improve your skills.

Before becoming an expert, learn English.
