I don't know if they work, but has anybody tried one of these?  You know what I'm talking about, a book or CDs that contain exercises that are supposed to improve your memory, has anybody had any luck with these?  As I respect you all, I'm willing to take your anecdotal evidence into consideration.

After fucking up the first test, which I blame on my choice to go snowboarding instead of studying, I've pulled my shit together and scored a 94.4% on the second test.  Luckily the professor drops the lowest test score. 

This test included drawing 3-dimensional shapes from rectangular rectangular 3 variable equations; converting equations between rectangular, spherical and cylindrical forms; describing 3 dimensional shapes (type, major axis, minor axis, axis of rotation, vertices); using the definition of a derivitive to determine the derivitive of vectors in 3 space; and 3-dimensional motion problems.

This test coupled with my quiz scores puts me at a 94.9% in the class.  Doing well both excites me to continue to do well and makes me nervous that I'll fuck it up.  I hope I can continue to stay on track with school, the subject matter is only getting harder.  Right now we're learning curvature in 2 and 3-dimensions and 3-dimensional curve drawings (helices mainly).
