Good track to learn a little bit more than kotlin basics. Well structured, with many topics. Good for searching specific subjects even after completing the track.

I have gone through the basics of programming. There was one question that needed more than one answer but I thought I needed to select only one. So this question took me many tries before I got the correct answer. Perhaps such questions could have more visual cues to indicate more than one answer is required.

So far, I have learned how to apply basic data types and how to convert certain types into each other. By means of the implementation of a "Connect Four" game, the knowledge about loops, "if-then-else" branches and lists from the individual lessons was deepened, among other things. It is a great feeling when after all the exercises the first "own game" works properly.
