Urgent: ISF 100D or ERG C100?!

<p>What class should I take? I'm an incoming student, and I dont want to take up a really difficult class. I will be taking these classes on a Pass/No Pass basis. Now, here are my concerns regarding these classes:
1. The reading lists for ISF 100D (found here <a href="http://ugis.ls.berkeley.edu/isf/resources/files/F10Dsyllabus-2.pdf%5B/url%5D"&gt;http://ugis.ls.berkeley.edu/isf/resources/files/F10Dsyllabus-2.pdf&lt;/a&gt;) list WHOLE books to be read. I'm not sure if they mean part of them, or they want us to read the whole book in a week.
2. The Final exam I looked at for ERG C100 seemed difficult.</p>

<p>So what should I do? PLEASE Help me out</p>

<p>Thanks a ton!!!</p>
