soo i graduate this year but i am switching to home schooling because it will be easier to take care of my son . anyway the school i was enrolled in last year said i missed a week this year right well i didn't know i was still enrolled in that school i thought I'd be okay considering it was summer break and i thought you had to sign up again every year well i am finishing the app for my new school can i un enroll to the school i am currently in ? or do i have to continue to go until I'm in the new one ? I'm17 so will i need a parent to get my transcripts and to un enroll
