Came to write this. Homework help services were specifically called out in our course policies as a form of academic dishonesty. Getting outside help on a problem set would get you kicked out of the major. It would take a lot of care to design a tutoring program that was specific to our courses and didn't run afoul of our academic integrity rules.

OP: this is a nice service for universities that allow this sort of thing, but you should be sure you're not running afoul of programs with stricter academic integrity rules (which, AFAIK, includes most top programs).
