I’m currently planning classes for my last semester of Community College and plan on transferring in the Fall.
Currently I am taking Calculus 1 and General Physics 1 (Non Cal based) and am thinking of adding General Chem 2?
Typically, people may be against recommending to having multiple science classes in one semester. However, if these are all the classes you will be taking then I think it will be fine. Usually one science class per semester might be easier but if you need to take two then do it, just be prepared 
As a science major, that sounds doable. But if you don’t do well in math or science classes, I would make sure you think you can handle it.
