<p>Me and all my friends get lost in this class. Any suggestions of book or website that we could review it before final ? I really worry about this class since final will be a month from now. </p>

<p>Could try Khan Academy. May be helpful.</p>
<p>These helped me immensely.

<p>[Index</a> of /~olver/am_](<a href=“http://www.math.umn.edu/~olver/am_/]Index”>http://www.math.umn.edu/~olver/am_/)</p>
<p>This helped explain some of the simpler topics in a more straightforward manner.

<p>The TA who is teaching the 307 class I’m taking this quarter uploads extremely clear online prelectures covering the fundamental concepts.</p>

<p>They may prove of some use to you.</p>
<p>Also consider the 18.03 (differential equations) pages at ocw.mit.edu, and the differential equations pages at mathworld.com and cramster.com.</p>
