What can you study before going to college?

Question

Android

I am 15 years old. I decided that I want to become a programmer in the field of IOS and Android and I think that I will not change this decision. I already know at least something in Java. I wanted to take courses on GeekBrains, but then I read the reviews and somehow got sick of it. What should I do, where to start and how best to do it. And are there similar programming services like GeekBrains? It seems to me that if GB gave quality courses and did not lie, then this would be a very good start. Thank you.

I would not be so categorical. As I understand it, you are just coming into the world of software development and have not tried much yet. I also once thought that I would be engaged in low-level development in C (well, there are system utilities, firewood, microcontrollers ..), even something worked out, and then I tried different directions and realized that interface development is much closer to me.
Since you yourself are interested in the topic, the institution will not become some kind of threshold to which the words "before" and "after" apply. You just keep doing what you are doing.
If I were you, I would pay some attention (it doesn’t make sense to give up everything and do only this, namely, in addition) to algorithms, data structures, issues of code organization and application architecture as a whole. This is general knowledge that will then be with you for a long time, no matter what you do later. The toaster has repeatedly asked what you can read on these topics. Well, so, they said right above: programming is a craft, here you can’t listen to a theoretical course and learn everything, so practice, practice and practice again.
