I found the radio button on the left side very confusing (see for example https://www.notclass.com/path/generative-ai/beginner https://www.notclass.com/path/generative-ai/beginner ). I expected each circle to be an option/question, not a different video. Now it's too similar to a curated watching list in youtube. It's nice that you can mark a course as completed (and unmark it). But I think you should add quiz (or something) as the sibling comment suggest. (You may write the quiz if you want to keep it B2C.)
