It is one trimester. It used to be two last year and that is why I had to drop band. I wanted to take band, german, and piano but they all didn't fit in my schedule... So I choose to drop band AND THEN I DIDN'T EVEN GET THE CLASS! I it was one trimester before then it would have all fit, but nooooo.
lol, sorry, I'm kinda p-oed at my school. They have strict rules about changing your schedule.
