Keep in mind with the two year transfer that some colleges, while they say they accept community college credits, may not count all the classes as equivalent replacements for their own graduation pre-reqs. You may have to redo some or take extras that cause you to spend 2.5 - 3 years at the four year college.
And even if they do accept every single credit, it may still not be all the required material, due to differences of what precise set of subjects were taught in the community college course vs. the exact class at that 4-year university that it is attempting to substituting for.
Someone will have better luck with courses further away from the path to the major degree than those that are closer to it.
