The interactive self-paced web development course comprises 48 levels, covering all the basics and several critical topics in web development. The course includes mini-lectures and many practical tasks, making it suitable for beginners and more experienced programmers.

We teach students to work with professional tools for development. We created the CodeGym plugin for WebStorm and IntelliJ IDEA to make it more comfortable for you. With the plugin, you can get a task in two clicks and submit it for verification in one!

What’s wrong? Where is the error in the solution, and why does the program work incorrectly? You’ll find the answer to this question in the requirement statuses. After submitting the solution for verification, you’ll see which requirements for the task have been met and which have not.

When you submit a task for verification, many tests run to find known standard errors. If such errors are found, you receive a recommendation from the task’s developer on how to fix the error best.

The best way to master new material is to practice it. But how do you know if your program works correctly? Someone has to check your tasks! On CodeGym, your code is checked instantly and automatically. You just need to click once, and if your program (solution) is correct, you’ll know it immediately.

In the "Help" section, you can post your non-working solution and ask for help or advice. You can also help others find errors in their programs. You can access "Help" directly from the task, and within the section, it’s easy to find discussions for the needed task by its ID or name.

We save your learning progress. If you need to take a break from solving a large task, that’s okay: you can finish the code when it’s convenient. Just submit the code for verification, and we will save it on our servers. You can return to the task from any device by logging into CodeGym with your account.
