1) I did not make calculation errors !!!!!

2) I got great feedback after 2 interviews for both PEI, my structures, and math.

The math actually clicked since I had seen much harder examples while reviewing. After our last mock interview, I also went through just the exhibit and math drills for about 4 hours, so even though the time I spent on it (1 week) was comparatively small, I feel like I had done just enough math to pass.

Thanks so much for having the patience to work with me through so many problems and basically give me a crash course in case interviews in such a limited time. I am extremely grateful.
