Starting over the summer will be a bit hit financially. Summer classes are a lot more expensive because they're through the main college and not the extension school. Taking summer Gen Chem will set you back >$6000, and then factoring in lost salary from those months... Ouch.
I'm glad I did it though. I think I've posted this here before, but I think the ideal post-bac schedule here is: Summer1 gen chem -> Fall1/Spring1 bio + physics -> Summer2 biochem -> Fall2 orgo 1 (add in calc and stats if you need them) -> Spring2 random elective + MCAT -> Apply. Doing it this way separates Bio and Orgo which are probably the toughest and most time consuming courses, and gives you a super easy final semester to allow you to focus on MCAT study, writing your PS, collecting LoR's, etc.
It's also just a really cool vibe taking summer chemistry. My fondest moments from the program are definitely from the first summer - it felt like being in undergrad again. A lot of people are living on or near campus, and everyone hangs around campus all the time because you're always going to class, labs, sections, review sessions, office hours, study groups, etc. During Fall/Spring semesters most people work all day, come to class at night, go home after. There isn't as much camaraderie.
