AdComs for medical school have no preference for where you take your pre-reqs, just how well you do in them. These classes will be oh-so-important as (if you are a biology major) it will be the vitality of the MCAT. Primary application cut-offs are all set on this statement "we only want applications above __ GPA and ___ MCAT score", not "We only want applications who took pre-requeisite courses from 4-years, not CC's".
In reality, AdComs won't even look at your transcript past the your cGPA and BCPM GPA as well.
I took my courses at a CC and found them to be more challenging than upper division courses at UCSD! Mainly because these pre-req classes at the CC now integrate upper division labs and other fun little obstacles to make getting an A a near impossible feat. There is no z-score calculation at CC's however and so expect a lot of B+/A- scores as a "top of class" type high schooler.
But you should still take them there, they will better prepare you for the rigors of medical school than a hugely curved pre-req course at a 4 year. Might as well get used to how hard classes will be from the get go.
Best of luck! 😳
