Course Selection for Junior Year

I was wondering whether I should take AP Comp Sci Principles or AP Comp Sci A as an elective.

This would be my first Comp Sci class, but both of them require no previous comp sci experience.

My other classes will be
APUSH
Honors Precalc
Honors Physics
Honors English 3
Honors Spanish 4

I am currently enrolled in AP Principles but this can be changed.
Any advice would be appreciated.

I think AP Comp Sci principles is exactly for people in your situation.
