Good way to get a head start on ODE's?

Hey guys, I'll take ordinary differential equations this summer. Class starts on June 4th. I wanted to get a head start on the topic because i'll take it with a professor that usually gives VERY hard exams, and I was wondering if anyone could recommend me a good site or something to start studying right away (even if it's only these two weeks).

Just got my book today, I got this one:

I saw that MIT has the course on OCW. Is that recommendable? Is there a better one that I don't know of? Thanks a lot in advance.
