Oh boy. My partial differential equations professor has emailed us and told us to review (ordinary) differential equations. I don't have a huge amount of study in ODEs (my diff. eq. class was a combined course with linear algebra) and was kinda hoping for a couple days of review. This class might just end up killing me. Send help.

Seriously, if you know of any good sources for reviewing ordinary differential equations, I could *really* use them right now
