Most Rigorous Schedule vs. Follow Your Passion - What do colleges really want?

Yeah, my D (who is a junior) is currently doing very well in Spanish 4 Honors, but she’d much rather double up on AP math next year (calc & stats) vs taking AP Spanish, as she just doesn’t enjoy it very much, excellent grades notwithstanding.

If her HS considered her 8th grade class Spanish 1 for placement, and she took 2,3, and 4 through HS junior year, do colleges view that as 3 years or 4? Now I’m a little concerned, actually, as she is going to be looking at some quite selective schools.
