I'm in my second semester of prerequisites at Community College of Denver and so far it's been fine. I have a BA in English too ...whoo. Somewhere I've heard or read that CCD is slightly better for prerequisites than some others, like CCAurora or Arapahoe, but it's probably not by too much. I don't know where I heard or read that. It might have been on here even, or from my CCD adviser (bias warning). But the science building and some of the teachers are shared between CCD and at least Metro. The campus/library is all a part of UCD, Metro, and CCD, which may contribute to CCD's being "better".
As for working...I worked all through undergrad, with no problem, and not surprisingly. Getting all A's would have been slightly difficult in the spring for pre-reqs with the 12 credit hours I was taking and working the 20-25 hours a week that I wanted. Through almost March, though, they were giving me 30+ hours a week, which I fought against constantly and should not have had to work after being there so long (blah, blah, blah). I was somehow lucky enough to be able to quit (become spoiled-student I never dreamed to be) and just focus on school, after 5 years at that job. Still got the 4.0 even with all of those 30-40 hour weeks.
I was crazy, however, thinking I would take 3 pre-reqs in the 10 week summer semester, work the 20-25 hours I wanted, and get the grades I needed.
Also, before I forget, UCD and CCD have an Integrated Nursing Pathway, and maybe their connectedness also somehow contributes to the CCD pre-reqs supposed superiority.
I just read above from Tebus about ACC having a cadaver lab.. well, I'm about to go continue some cat dissection, which is the creature of choice at CCD and Metro, if that at all adds to the consideration.
