Course help?!

I am taking anatomy and physiology as a sophomore in high school. I thought it would be an interesting and fun class to take. Turns out that I need to divert a lot more attention to it than I thought. I get home everyday at around 6 o clock and don’t have much time for homework. I am taking all honors and an AP. I can tell that throughout this year studying for anatomy will take away studying time from my other non elective and ap classes. I also think it will lower my gpa. Is this class worth my time? What do colleges think about taking a and p as a sophomore as well.
