Will my Community college engineer transfer plan work?

@ucbalumnus and @LakeWashington Hey guys so I just wanted to keep you updated I will not be taking calculus II over the summer because my it is very hard from what people have told me. However in my spare time I can get a internship plus still work part time. So how does my new plan sound? So

Fall 2015 I will be taking Calc II and CIS
Spring 2016 I will be taking Calc III (Math 209)

Or should I take Calc III (Math 209) with Physics 235 ? If Calc III with physics 235 seems hard I will just have to take it at a university because in the summer 2016 I plan to take linear algebra.

Since these classes are not 12 credit hours or more I will have to pay out of pocket. With my part time job and my scholarships i have recieved I have enough money saved to pay for the classes. Also do I really need Composition II if so I would rather take that this summer.
