It prob depends on the person, but you could prob go either way. I think if you dropped world music and picked up physics, it would not be a horrible 17 hours. The pre cal is prob easier and the American history probably isn't a huge time commitment.
However, may not be bad to chill and take physics next semester, which would not be bad for your prereq schedule if you are starting sophomore year this fall. This way your GPA won't be threatened by something you could have put off anyways. You could use extra time to get involved with some weekly nonprofit volunteering if the schedule ends up too easy.
It's probably a question of how easy the math in physics would be for you. As a sophomore myself, I get trying to get more done but it may be nice to protect the GPA and do some other activities instead, especially since Organic may suck. Either way, good luck! You have options
