There’s a student who had a choice between UCB potential CS admit vs. named scholar at Georgia Tech wih guaranteed CS… he picked UCB.
To me that makes no sense (both are prestigious and one is safer) but 18 year olds like gambles.

Wasn’t that student trading off the assured major at GT for the lower price at UCB? Not always an easy choice to make, and one where reasonable people may choose differently, unlike the situation where the assured major happens to be that the school that costs the same or less.
