Which Class should drop

By the end of February, I have to pick my classes for next year and I have to drop an elective but I don’t know what is better to drop.
My schedule for next year includes
LA Honors, Ap Gov, Ap Calc AB, AP Environmental Science, AP Psychology, and Orchestra
Out of AP Environmental Science, AP Psychology, and Orchestra should I drop one for bioengineering. Right now I’m leaning towards dropping orchestra for bio eng. but the only thing stopping me is my mom thinks I should stay in orchestra because I’ve been taking it since middle school and it’ll show colleges is dedicated.But at the same time, it does not count towards my GPA. Or should I keep orchestra and drop another class.What would colleges like to see? Also, if you have any tips on any of my other classes please share.
Thanks

Actually, Should I drop Orchestra for bioengineering

You should forget AP ES and take Bio, CHem, Physics or an AP Version of one of those.

I would keep Orchestra if you enjoy Orchestra. Don’t worry about what colleges think as much as do you enjoy it and all the friends you have there.
If you want to take Bioeng too, I would drop AP Psych.

If you really want bioengineering, drop AP psych.
Do you enjoy orchestra? Are you good at it?
Did you reach level 4 in a foreign language?
Do you have one year each of bio, chem, physics?
