What’s the next step after finishing my first course?

Question

I just finished Python on Sololearn. Should I jump into another course? I could go back and review a few topics that I didn’t quite understand. I plan to dig into the challenges a bit more as well, now that I’m a bit better equipped. What did some of you guys do after finishing your first course? And what would you guys recommend as paths to take on my road to becoming a programming master?
