Thanks to the excellent college counseling program at Hogwarts, he has done the required self-reflection and research. In addition to having a human counselor who actually counsels, they also use a computer program which has been very helpful. Bossy describes something similar here.
I do know that Ernest submitted 3 early applications: Northeastern, Drexel, and Worcester Polytechnic Institute.
Northeastern University, in the heart of Boston just a few minutes walk from Fenway Park, is his number one choice, due to the co-op program. On our tour last summer, we learned that they have the only Taco Bell in Boston.
Rub the Northeastern Husky's nose for good luck!
Drexel University, in Philadelphia, was also a stop on our college road trip. Again, the co-op program is a plus.
Although Drexel's mascot is a dragon, their good luck charm is this statue's toe.
WPI was a new addition to his list, probably due to the proximity to Boston. "WPI was founded in 1865 to create and convey the latest science and engineering knowledge in ways that are most beneficial to society." Well, that sounds like a good fit for him.
If he gets accepted at Northeastern, he's done! If not, he'll roll out another series of applications at the next deadline. (Boston University for sure, plus a couple "reaches" and I don't know what else.)
