Spanish (LISP) at UCSD

I am currently deciding whether to take Spanish along with CHEM 6B or whether to keep MATH10C with CHEM 6B.
At this point I am trying to take which ever class is easier, and would give me a better chance at getting a higher GPA. I am a native spanish speaker so that would definitely give me a better chance with the Spanish course.

Does anybody have an info on the Spanish courses at UCSD? I tried looking into them but couldn’t find any feedback from students. Thanks for your advice in advance!
