Hi deb,
Could it be that perhaps you just aren't a good test taker?? That's how I was in school. My test scores didn't show my overall intelligence.
Gosh, if you alone wrote your post.... you seem to be way above a 2nd or 3rd grade level. You used the words "mandatory", "comprehension" and "theraputic"--- not sure if I'm missing something these days.... but those sure don't seem like 2nd or 3rd grade words to me. I bet you are way smarter than those tests are showing and smarter than you give yourself credit for.
My son is in high school and is dealing with ADD. The school he goes to doesn't have a program especially set up for ADD.
Maybe you can talk to a school counselor and see how they could perhaps better accommodate you? Since you like your new school-- maybe something can be worked out. Like for example: My son gets extended time on tests and semester finals-- so his momentarily wandering mind won't bring his scores down. Maybe that's a place you could start at??-- getting extended test time.
And hey, who's to say you won't be happy in your future profession? --- I believe your future can be very bright!
I wish you luck.
