I think some more info is needed in order to help out with your situation. How many credits have you completed? Have you taken upper level bio and chem classes? Your spring classes will show up on aadsas if you finish up before you apply and then of course you have to show the classes that are in progress and classes that you are planning to take. I don't think the adcoms are impressed with seeing the "in progress" classes as they would care more about how well you do in them. A 3.2 science gpa is low and I would recommend taking more classes to boost that up but it depends on how many credits you have already taken. For example, my last five semesters I had straight A's but it only raised my gpa up a tenth of a point because I had already taken a lot of classes. I would also recommend studying like heck for the DAT. If you could dominate it, schools could overlook your low science gpa and focus on a high dat score. And definitely apply early!
