<p>The course description says "Equivalent to 1A-1B plus 15 as prerequisite for further courses in chemistry." Does that mean Chem 1A/1B (and 15, ***?) are prerequisites for 4A or for doing higher courses?</p>
<p>Also, what is the difficulty of this class? I've heard the labs are killer, but is that it? Did anyone else take this class as a freshman?</p>
<p>Oh, as an aside, just how do the labs work at Berkeley?</p>
