Just because she is in special ed doesn't mean that she is doomed as far as college goes. Check into community colleges when the time comes, many have programs that may be a good fit for her. Encourage her, help her with homework or see if there are tutoring programs. If you have a local college many times college kids will be willing to tutor and sometimes high school kids will also to get that volunteer credit. Just because she is in special ed now doesn't mean she will always be there. I worked in a special ed room for a while and we had kids in there that would go into mainstream classes for some coursework and be in our room for other stuff. Stay postive about her future so that she can be also.
She has a tutor.
I can't help her with her homework for two reasons. When I do, she gets it wrong because I got it wrong. And we don't work well together.
