💻 Learn By Doing

In this course, you learn by doing! Each concept has several interactive challenges that you will solve to pass on to the next one. We believe that hands-on learning is the best way to get in-depth knowledge. Here you will have many challenging and at the same time interesting exercises to practice each and every concept that is covered.
You will study at your own pace. You can go hard and complete several levels in one week, or take it slow and focus on each concept for longer.
There is a forum to ask questions and get unstuck. You can ask or answer the questions of others under each challenge.
