Should I drop Spanish for Latin?

I recently dropped Spanish III Honors for Spanish III because of the intensity of the class. I simply could not understand a word the teacher was saying. However, I am currently enrolled in:
AP Computer Science A
AP Human Geo
Honors Chem
Honors Alg II/Trig
Honors Choir(involves tons of extra work)
Honors English
Actor’s Workshop
and of course
Spanish III
I heard that taking Latin would help me on my standardized tests, but I would obviously have to start from the beginning.
I have lost all interest in Spanish and Latin sounds much more interesting, but I am wondering if having inconsistent languages would raise a red flag to collages.
I am a sophomore.
Should I change languages this or next year? I take my SAT Junior year.
