<p>I agree with redzune about CoC. It is not a college (alot with CoE) in which you want to hang out major-wise and experiment. If you get accepted to berkeley but don’t know what to major in, stay in College of L&S. </p>
<p>It is actually a good thing that CoC has made Chem 4AB mandatory. Chem 4AB is much harder than Chem 1AB. Chem 4AB will weed out students at the earliest oppurtunity and that will allow some student to switch to other majors. CoC can’t turn Chem 1AB into a weedout course because all freshmen take Chem 1A and so the course load in Chem 1A must be manageable. </p>
<p>Come to think of it, I now regret not taking Chem 4A in fall 1996, in which Chem 4A was optional. Had i taken Chem 4A, i definitely would have changed major. I took Chem 1A 1B and eked out an A- in both classes. But when i got to Chem 112AB and ChemEng 140, my grades dropped to Bs. In my last two years, my GPA was a dismal 2.3 </p>
<p>To all you CoC admits, GOOD LUCK!!!</p>
