Moonkin,
I'm sorry about your car. Yes, you had a stressful day!
Those tests are a b***h! I just had to take the GRE and, like you, I guessed on many of the answers, especially the math!
When I was in high school, long ago, I took the ACT and did terrible on it. I have test anxiety and a kind teacher gave me a book to help prepare for the SAT. It helped immensely and I did much better having had the practice tests. It won't help you with the answers, of course, but it helps you pace yourself and learn to focus on the nature of the questions, etc.
I hope this helps.
Patty
