Learn by doing

# 1

Apply knowledge into practice

You already know the theory. Now it's time to code like you do at work—in a professional IDE, with real project constraints, solving problems that actually matter. Welcome to software engineering as it should be.

# 2

Navigate complexity with surgical precision

Most developers waste months learning random concepts without seeing how they connect. Our interactive Knowledge Map fixes this. It shows exactly how every programming concept relates to others, helping you build a structured mental model of coding.

# 3

Copy the best. Then improve.

Here's what top engineers do that others don't: they study other people's code obsessively. When you get stuck on Hyperskill, you can explore solutions published by other developers. See their exact code. Understand their approach. Learn their tricks.

# 4

Code review that actually makes you better

We stripped code review down to what actually matters: does your solution work? Have you handled the edge cases? Is there a cleaner way to write this? Hyperskill acts like a competent reviewer who actually tests your code. Not genius-level analysis, not architecture debates — just solid feedback on making your code better.

Elevate your engineering mastery through real-world challenges

Master advanced engineering concepts through ambitious projects. Each project deepens your expertise and transforms you from an experienced engineer into an exceptional one.

Desktop Tic-Tac-Toe

Everyone is familiar with Tic-tac-toe. Create a version of this game using the Swing graphics library. Teach a computer to play this game and compete against both your friend and AI.

SQLite Viewer

Sometimes we need a tool that shows the database contents — tables and the data inside. You can write an application that will allow you to look into the abyss of your database.

Text Editor

Looks like you like challenges! This project, however, is not too tricky if you’re feeling like an advanced learner. A text editor you’re going to write allows to search for specific files and open them. Check out the prerequisites, and if you’re ready, let’s roll!

After completing this track, I learned a lot about multithreading, the GUI libraries AWT, Swing, event processing and much more. In general, a very useful track for those who want to master window interfaces. The only thing is that the tests are very strict and not very informative, forexample: Test ...
