Thank you guys for all your good vibes, thoughts and well wishes! I did it!
It took me maybe two and a half hours (the longest I've ever stared at a computer that wasn't on TCS!) and here's what I got:
Reading: 184, I needed a 179 so you can see I barely made it.
Math: 186, and I needed a 171.
Now I just have to wait 2 weeks for my writing results... I felt good about the essay, which was half of it, but now I'm getting nervous because I'm not sure I fully answered the question.
BUT... I made it this far! Thanks for everything!
