Should I take AP Biology for 10th Grade and wait until 11th Grade to take French 1 or vice versa?

My current schedule (with AP Biology) is : AP Bio, Honors English, Honors Chemistry, Honors Geometry and Honors Algebra 2, World History, and Study Hall. The schedule with French 1 is everything except AP Biology. I really would like to take both subjects in the same year except there are scheduling conflicts in doing so.

You need a foreign language more than you need to double up on science. Save AP bio for a later year.
