High School Class selections

I am going to be a junior next year and I was wondering if this schedule would work for me:
AP Biology
AP US History
AP Calculus AB
Spanish 4 Honors
Physics
I play volleyball and run cross country
I tutor kids and I run the MUN club at our school
Our schools has a block schedule so should I consider taking another class such as an elective?

English course?

If your school has block scheduling, what would you take semester 1 and what would you take semester 2? Does AP bio get a double block?

I think you should take an english course.

Sorry i forgot to list that i was taking English 3 Honors

Why double up on sciences?

Get rid of physics or bio.
