I signed up for band, and school starts tomarrow but Im really tired of it and want to change to business or technology or whatever else there is. Ive already done it for 6th and 7th grade and im just bored now. How do i change it?|||Talk to you councilor. Sometimes they have to re do your whole schedual though. When I was in high school I wanted to drop one of my math classes (6th period) and they ended up mess up my 6th period and 2nd period. Depends on what classes they have at what times |||Go to your counselor and ask them to change your schedule.
