<p>i feel stupid
i found what books are needed in online course synopsis
but i didnt see like 5 books on chem 21l & its lab component.
is there another (detailed) website with lists of books for each classes??</p>

<p>let me know plz :D</p>

<p>If you go to the textbook store site, that's all that's listed. It's like, $520 in textbooks, but if you notice I think some of them overlap and all. I'm just going to wait until I get to Duke and can see a tangible copy of easy item listed, so I know what I need.</p>

<p><a href="http://dukebooks.collegestoreonline.com/ePOS?store=320&form=shared3%2ftextbooks%2ftext_browse%2ehtml&design=duke_textbooks&campus=MAIN%5B/url%5D"&gt;http://dukebooks.collegestoreonline.com/ePOS?store=320&form=shared3%2ftextbooks%2ftext_browse%2ehtml&design=duke_textbooks&campus=MAIN&lt;/a&gt;&lt;/p>

<p>loveduke22, that's smart.. i think i might do that too.. except i'll buy the textbook early because i know i'll be needing that for sure..</p>

<p>EDIT: nevermind they changed stuff this year</p>
