Last year I had 7 AP classes and still managed Robotics.
It's not impossible at all.
What makes it hard is learning how to manage your time.
Obviously, you have 24 hours in a day and school, robotics, homework, etc. to attend to. (I was "oh so lucky" last year and had all this plus tennis team...where I was #1 and Envirothon where we were going to states).

24 hours is a lot. You may end up cutting up on a bit of sleep but you dont' have to go crazy. Just don't waste your time. Do you have time during transportation? Use that time as your unwinding time or work on something else. You can easily get in a few math problems or think about the next essay you want to write.

It's all about being on your toes and not overthinking things. Thinking about what you have to do will stress you out. Make organized lists and if anything, schedule out your time. And leave time for de-stressing yourself, it is important to take care of yourself just as much as it is to take care of anything else.

If you have any personal questions or want advise or just want to hear a good story, don't be afraid to PM me. Good luck =)
