Freakin out!!

So it’s not my first year of high school, it’s my second. I think I’m scared more than I was going into my first year because I decided to take harder classes. It sounds crazy stupid to be scared of but the thing is, I don’t want to spend my high school year just focusing on studying for my hard classes, I also for sure don’t want to fail those classes. I want to have fun. I want to be able to join sports, clubs and still take some hard classes with AT LEAST AN AVERAGE GPA!! I’m freakin out, and I think I need to stop!!
