I know what you mean about trying to keep sane. I was really worried I would be denied, checking my email and mailbox regularly hoping for something. At one point I was convinced I would be denied. I think what did it for me is that I stayed in touch with them for years, getting classes pre-approved and showing my commitment. I took time off work to concentrate on the GRE, and visited for open house right after applying. I also went for the best letter writers I could find, and really tried to shine on the personal statement. That's what I think did it, because there was nothing really special about my numbers (GPA, GRE). Not bad, but not great either. I started thinking about engineering 4-5 years ago during law school. I became really interested in science and math and I wasn't sure why I avoided it for so long. I really want to go into patent law, or engineering itself.
I hope you get in as well Adamlau. It's apparent you appreciate the opportunity LEAP offers, and I'm sure they see your commitment as well.
