<p>If you want to get a good idea of how hard the courses are, you might want to look at the course webpages for freshman courses (which have problems from this year):
Ma1a: [[Ma1a</a> - Fall 06-07] - Calculus of One and Several Variables<a href=“homework%20set%207%20will%20give%20you%20a%20good%20idea%20of%20the%20difficulty%20of%20the%20class%20:p”>/url</a>
Ph1a: [url=<a href=“http://www.its.caltech.edu/~tmu/ph1a]Physics”>http://www.its.caltech.edu/~tmu/ph1a]Physics</a> 1A: October 2007 Course Calendar](<a href=“http://math.caltech.edu/classes/ma1a/index1.html][Ma1a”>http://math.caltech.edu/classes/ma1a/index1.html)
The chem1 stuff has been removed, but I don’t think they want you looking at previous year’s stuff for that class anyway.
(Oh and don’t look at the solutions of course :))</p>
