I would have to agree with preludexl! P chem is THE HARDEST class I have EVER taken in my life. ****, I barely passed in fact...I would have never taken that but if UCLA requires you take it if you are a biochem major....like I was. Anyhow, immuno and microbio are topics you will encounter early on in dental school...well at least at USCSD. I would also recommend neurobio as you will need to know cranial nerves and etc...
As for USC...hmmm you do know that USC is PBL curriculum right? So let me tell you the pros and cons of PBL...
PROS:
1. Because you are learning in group, and you research ALL of your learning needs by yourself and with the group, the stuff you learn will stick with you a lot longer than if you are just spoon fed the material in a lecture envt.
2. Because there are NO lectures, you have A LOT of free time in which you can study, take naps, drink etc....
But that does not mean that you cannot study, BUT it gives you the option to actually having a life outside of schoo. My gf goes to BU dental and she's in class 8-5 while I am in class from 8-12pm!! So you use the 'free' time after school to research your learning needs and share it with your group members.
3. Because PBL is cased based, that is they present the material through various medical and dental cases, you tend to retain the knowledge better (related to #1 above). You tend to think of scientific facts by remembering the cases not the fact itself...so again you retain it longer.
CONS
1. There are no books that USC issues. There are no formal professors, only facilitators. Sometimes you feel like you are not being guided at all.
2. Because you are separated into groups, you tend to know only a certain percentage of people in your year. In fact I am still meeting people that I haven't seen before, and I am half way through my first semeter already!
3. USC does not have the necessary facilities (rooms, computers, library books) to handle 144 PBL students needs. Well, at least right now...hopefully they'll do something about this...
OVERALL, I like the PBL program. It's more kickback but I feel like the things that I am learning are really sticking with me. If you didn't like the whole lecture setting in undergrad, or you think you are one of the people who like to procrastinate, you might want to give PBL some serious thought. The program is structured in such a way that you MUST study as you are held accountable for your group member's learning as well. It sounds fishy, I know, but you must experience it for yourself to fully appreciate it. I have to be honest, not everyone is happy with the PBL curriculum, especially in the beginning, but it grows on you. And I would say that the people who dont like PBL are in the minority. Hope this helped!
