In general what should I memorize?  In the assigned reading PDFs, do I need to memorize every equation where it says "Know equation xx.x.x"?  Is that enough or do I need to even memorize those (ie will they be given in the problem)?  I'm assuming no formula sheets are allowed?

[NEAS: Know the equations mentioned. If you understand the material, many of these equations are straight-forward. Some exam problems can be solved directly from the equations, so it is useful to know them.]
