With the exception of a few schools that absolutely won't take CC credit, it's really not a big deal, and I would HIGHLY recommend taking 2 years to transfer, finishing your Gen Ed, and at least completing General Chemistry so you can take Organic once you transfer. My frame of mind was that I looked at the school I wanted to transfer too, and I took all of the science classes that Freshman and Sophomores would be taking there, so I wouldn't be behind once I actually did transfer. For some other reasons I actually ended up staying 3 years at the CC, and in that time I finished all my gen ed, a year of bio, general chem, Organic chem, and physics, and then I transferred and had a very enjoyable time only taking upper division classes, doing research, and focusing on my classes to do the best I could.
So, definitely take at least Gchem, most bio majors take that freshman year, and it's often a pre-req for other classes.
PS. As for preparation, I found the majority of my science professors at the CC to be far better teachers than most of the ones at my university.
