Jesus christ. The preliminary exam is in just a month. I got two of the previous years' exams which I've been studying, and a few folks in my lab gave me the exams they were given to practice on as well but christ. How am I gonna pass this thing.

I've been doing the online thing, sort of half-assing these classes because they have nothing to do with my research, but the day of reckoning has finally come.

Any /doctoral/ students take prelims and have tips? How can I best not fail this thing, bringing shame upon my household.
