hi! If I were you I would do as many languages as I could. They are fun and the more you do the easier they get (although continuers courses are more fun than extension courses as the literature can take your focus off the actual language learning.) Do whatever your school offers and then Open Highschool - there's beginners levels for like 10 different languages.
I don't know why more people don't use this opportunity. If I could do it all over again all my subjects would be languages. People PAY to learn them later in life when you can do them now FOR FREE. If not for any other reason, it makes economical sense. Also, the small class numbers make it practically like you're getting private tutoring lessons. People who just throw away this chance are crazy in my opinion, unless they really hate languages or they absolutely love their other subjects (maths, science, history, economics, whatever). In my experience all those other classes tend to have huge numbers and are never really as fun or personal (I did maths and science then quit because they were so boring).
This is just what I find to be the case. Don't be intimidated just do it for fun! =)
