What is your assessment of my college list?

Thank you for the congratulations, everyone. This certainly feels like the first validation of my efforts.
@PeaceOfMind, thank you for the information. I’ve heard of Pomona and was considering it for a bit. Seeing as circumstances force me into engineering, I don’t think I can add liberal arts colleges. I need colleges that have engineering (preferably aerospace, electrical or petroleum).
@theloniusmonk, yes, I am considering both schools.

As a separate question, how much do you guys think being a Questbridge Prepscholar increases my chances when applying to a partner college? If I had, say, a 50% chance of being admitted without QB, how much have my chances increased?
