Is there NO WAY that they can give you another chance so that you won't be dismissed? Then if you can really buckle down and get your grades up, perhaps you'll be able to stay in school? What do you think?
Why don't you talk to one of the counselors? They might be able to help. I would. I'd talk to a counselor.
I'm sure you're not the only one who is having trouble -- it seems they would give kids a chance. But I have no idea really.
I wish you the very best. Please let us know what happens, will you? God bless and please take care. Hugs, Lee
