I play games in school, but that's too risky, parents can walk in anytime, I also just watch youtube, not pay attention, and get good grades :)

Getting good grades isn't all you need to do. Make lots friends and get a very important skill you'll need later in life. Try and make your studying fun, turn it into a game. For example math, try imagining that the problem you're trying to solve is needed by a captain in a spaceship in order for him to get across a wormhole. And one last thing, Don't lose your creativity in the process and learn to code.
