Hi Everyone

If you train regularly on Codeforces, you’ve probably faced this

You open a gym
You see a long list of gyms
You spend time deciding what to solve

Is this too easy?
Is this too hard?
Is this even useful?

This step wastes time and breaks your focus.

Most people don’t struggle with solving.
They struggle with choosing what to solve.

The Idea

I built Upsolve.it

A tool that gives you a structured way to train based on your level

• No random picking
• No guessing
• No wasted time before solving

How It Works

1) Level-based training

• The system reads your Codeforces rating
• It assigns a training level automatically
• Each level gives you 4 problems with increasing difficulty

You can also

• Adjust the level manually
• Filter by tags
• Keep it fully random

Problem difficulty stays hidden during the session You focus on solving, not judging

2) Training session

When you start a session

• 2-hour timer
• Solve problems directly on Codeforces
• Sync your submissions with one click
• Track accepted and wrong answers

It feels close to a real contest

3) Upsolving

This is the core idea

• Every unsolved problem goes to your upsolve queue
• You return later and solve it properly

This step builds real skill

Tracking Progress

The platform gives you feedback over time

• Activity heatmap across the year
• Session history
• Performance trends
• XP system and levels
• Recommended difficulty for your next session

You can clearly see if you are improving

New Updates

I’ve recently pushed a set of updates to make the training more structured and useful

Streak System

• Daily training streak
• Upsolve streak
• Consistency score

Time Tracking

• Time per problem
• Detect slow solving
• Feedback after each session

Session Review

After each session, you now get:

• Where you spent too much time
• Which problems were easy
• Which were above your level
• What you should focus on next

Training Modes

Different ways to train:

• Ladder mode
• Weakness mode
• Speed mode
• Contest simulation
• Endurance mode

Friend System

• Send friend requests
• Connect with other users on the platform

Why I Built It

I kept seeing the same pattern

• People jump between problems
• They skip upsolving
• They don’t track progress

So improvement becomes slow

This tool fixes that
