Like they said, don't freak out! I work as a tutor and an aide in school. May I suggest getting a tape recorder? Read your notes into it and play them often. It works for essays, too. Just start talking about what you want to write about, then listen to it in chunks while writing it out.

Incidentally, Spanish gave me my first (and only) "D" in college- and I still graduated with honors in spite of it. At the worst, you end up in a 2 year, community college. That will give you 2 years to get those grades up- then transfer to a 4 year college. They won't even look at that "D"- your more recent grades are much more important. So get busy, tape your notes and don't give up so early in the game! - Granny
