I have already taken both General Chemistry 1 and 2 at my community colleges. I did not get a good grade, but that was because of I missed a lot of homeworks and projects, but did good on the tests and I understand some of the material that I learned. In general, can you take both of them again at the same time at university level. I'm transferring at a CUNY college, but in general, are you allowed to take the chemistry sequences at the same time. I know you probably can't if you are just beginning, but If you already took them, is it possible?
