I'm a sophomore and I'm currently doing my last year of Spanish (the college I plan on going to only requires 2 Foreign language credits, so I'm finishing up those). Spanish is a cool little language to learn once you get the basic 'rhythm' down.
For my recommendation, I would honestly say to start by researching what college you plan on going to (if you do plan on going to college). Most colleges require 2 credits in any Foreign Language class during High School, but there are some that don't require any (but you reap better rewards for learning it) and some require you to take a class all throughout your High School career.
So, bottom line, just be aware of how many foreign language credits the college you (might) plan on going to requires, and pick the one you think will not be as troublesome to you.
