Yeah, at my undergrad it was called Cell Biology. At my postbacc school, there are actually two intro level series -- one's called General Biology and the other is Principles of Biology. General is for non-science people, and Principles is for majors and pre-professionals. I wonder if adcoms can catch the distinction or not. General Bio is 100 level, and Principles is 200 level.
Anyway, schools call them lots of different things. Getting back to the main topic, I think it's best to take the full year intro biology sequence because some schools really do require it, and it's just good prep for the mcat. Also, it gives you a good foundation in biology and general scientific topics. I thought Principles would be a big waste, but I really wound up enjoying it.
