Homework is your priority. Get your homework done first, Study a couple hours for tests, and then spend the rest of your time on CD, doing robotics and playing video games
You will have a great life, then!
During build season, many more hours would be spent in robotics. Talk to your mentors if they can have a set amount of Homework time, where you are supposed to be doing your homework. Or even better, if the student finishes whatever homework is possible for them to finish (because some will need textbooks that aren't available), then they should be allowed to do robotics
