<p>i'm a pre-med IB major (possibly MCB i guess).</p>
<p>can i take chem3b in the upcoming spring and then 3bl some other semester?</p>
<p>Yes, it is possible. I took Chem 3B over the summer, and I’m going to take 3BL next spring.</p>
<p>what are the disadvantages of doing this though?</p>
<p>Nothing really, other than the fact that you have to revisit concepts you learned in Chem 3B in another semester.</p>
<p>bottom line: It is very doable to take them separate, tons of people have done that and survived and gone of the med/dent/opto…/etc. school just fine, though if you can take them together and not have an uber-crappy schedule, I don’t see why not</p>
