<p>So I'm a 2nd year chemistry major in CoC and according to the recommended schedule, I should be taking pchem 120A next semester. But I talked to one of my friends and she said 120B is much easier and I should take it first especially since I haven't taken Math 54. I was planning on taking Math 54 concurrently with 120A, but she said I wouldn't understand anything in 120A if I haven't finished 54. </p>
<p>So any suggestions, personal experiences as to which I should take next semester? Thanks!</p>
