The student:professor ratios at Boston University CS classes were much higher. I didn't realize the importance of that until i had this comparison with the other institution.

It led to many fewer questions by students, teachers assistants (something the other institution did not have and did not need because one professor could attend to all of his students), and in general less interaction between students with each other and with professors/TAs.

The curriculum at both were essentially the same for this set of classes.
