Not sure if this information is out there or not, but here is how they are handling the student tickets this season...
Last year they just randomly "dropped" a university wide alert - "Student tickets will become available via this link at noon today." So at noon everybody would try to get in to some online portal and claim their ticket. It was a free-for-all... Some students would be in class... not a great way to do it.
This year NU developed a point system, whereby "credit" is awarded to any student who shows up to attend any Northwestern game for any "Olympic" sport. So if you go to the women's soccer game you get some points. Points aggregate and the people with the most points get first priority for home men's basketball games. At least thats how my daughter explained it to me. On its face it seems like an interesting approach to get students out to watch their classmates compete.
