  • I am stuck!
    Have you heard of CheckIO (https://checkio.org/)? They have a gameified "Mario world" of coding challenges that are smaller and come with more explanation, tests to guide you through edge cases and provide hints. The challenges start from total beginner and progress to more advanced. And best of all, after you solve a problem they show you what other people do. I highly recommend this for you.
