I have set up a training for beginners, The training focuses on solving various problems on Codeforces. Training that contains: 100 Problems (A) and 100 Problems (B). and 50 Problems (C). Tags of problems in the training: Spoiler. Problems Difficulty: from 800 to 1500.

- If you are a beginner in competitive coding then don’t directly jump into the contests. First, go into the PROBLEMSET option and set the difficulty level from 800-1000.
- Try giving all the contests (there are 2-3 contests every week). Initially, it is possible that you might solve 1 or 2 problems in the contests, or it also might happen that you were not able to solve even a single problem, but you don’t have to lose hope and keep practicing the problems.
- As contests are time-bound, so you also have to focus on them and should try solving problems as fast as you can.
- Watch editorials only if you have given sufficient time to that problem and don’t watch editorial completely, first see the tags and then start thinking about the problem again.

This is a post on how I believe is the best method to practice modern day competitive programming based on my experiences. I assume you already have some knowledge and know simple things like binary search and dfs/bfs, but read the footnote if you are complete beginner(never code, solved <50 problems, div2 A/B too difficult, grey or stuck low pupil...
First off, what is the main goal in practicing efficiently? I would argue you want to come across as many subtle ideas and concepts as quickly as possible and learn to intuitively realize when to apply them and what they have in common.This is what my practice method is centered around. Another important goal is you should also feel discomfort in e...
So, why only codeforces? Well, recent codeforces problems do a decently good job of introducing a large variety of concepts, particularly in the 2000+ rating range. Thanks to the large standards of wanting non-standard problems each contests, many small math tricks and greedy techniques are introduced, along with standard algorithms and data struct...
Alright, so codeforces seems good. Why only a rating range where you can solve ~30-40% of the time? Shouldn't you be practicing coming up with solutions on your own? Well, like I said earlier, you want to come across as many concepts as quickly as possible. If you're able to solve ~80%+ of the problems you're doing on your own, even if it takes a w...
Next thing to come up is when in this am I supposed to learn new standard algorithms and data structures? I advise when you come across an algorithm or any other concept (maybe math idea) in an editorial you don't know about to immediately find and read an article about it, implement in the context of this problem, and then continue just moving dow...
The number one thing that probably looks wrong with this practice method, despite the reasonings I gave earlier, is that you seem like you are not practicing solving problems on your own often enough. This is where live contests come in. It is important to take part in as many live contests as possible from every judge you can (except ones where ev...
This is less important but more just some pointers on scheduling time to practice consistently. I think it is obviously best to practice daily, and it isn't as hard as you may think it is if you build up good habits. I think it is good to have a regularly scheduled time where you can practice each day, as this makes it more of a consistent habit. S...
If you are training for some main goal (hopefully for the past several months at least, following above methods), when you are within a few weeks away of big contest, start spending more practice time on vc's for that contest, and look over the syllabus/relevant ideas for that contest if list exists. Also consider if you are in these pitfalls: You ...
Hopefully this was somewhat useful to some of you, and gives you a comprehensive guide on how to practice for USACO and competitive programming in general. Please share this with others if you think it is useful. For any more experienced people, let me know if there is anything you strongly disagree with what I said, I'd be interested to hear your ...
**I recommend the beginning of the usaco training page to complete beginners. I think it is a good way to start out as it guides you on the basics, and you should be able to start as soon as you know the very basics to a programming language, preferably c++ (you can use codeacademy to learn basics, it should take only a couple days max. you learn o...
Yes, you need to get what is the problem about, unravel some layers of reductions and implement the solution, but in a nutshell you know how to do every small part of the problems you will solve in the contest before the contest even starts.
Jun 20, 2023 · Here are the steps I follow for up solving: 1. Make a genuine attempt to solve the problem (allocate sufficient time). 2. Review the topic tags for hints and read any available hints. 3. Seek...
In this blog post, we will explore effective strategies and techniques to tackle questions on Codeforces and improve your problem-solving skills. 1. Understand the Problem:

What should I do if I'm New to Codeforces?
Why should I use Codeforces instead of other sources?
How to start with Codeforces?
How good are Codeforces problems?
Many people new to Codeforces seek advice about how to get better / which problems to try. Other people are stuck on gray / green even after solving a lot of problems. This roadmap aims to be a solution. My take: to be good at competitive programming, you have to know "what to think" and "how to think" when you try a problem.
