The one thing that does appeal to me is the possibility of linkages and skipping the glide year.
I don't get excited about linkages. The people in a postbac program who say "we'll take care of you" don't actually have any power. Show me a med school that reserves SEATS for N grads of a postbac program. Using a postbac program to get interview invites is a lot of money and effort when you can get an interview on your own merits.
That said, the structure of some of the postbac programs is worth the money. I rolled my own at a state school, and I wish I'd gone to Bennington.
I don't think you're skipping a glide year. Even if you can get your prereqs done in a year, you still have to take the MCAT after that year, and then you're ready to apply. And then you get to glide for a year.
(Others: am I on crack? Are there actually postbac programs that in one year simultaneously give you your prereqs, your MCAT, your application, and your interview, so that you start med school 1 yr after you start the postbac? If so, somebody shoot me.)
I'm a former engineer as well, so I completed math/physics/chem in the 80's. Last year, OChem slapped me silly: be ready to have your butt handed to you and be ready to STUDY even if you never needed to before.
So: if you feel like you're still on top of the material from gen chem, I'd pick a school based on its ability to fit your scheduling interests. If it's a big enough school to offer multiples of the different classes and labs that you need, that's good. You might not find a school that separates gen chem lecture and lab, and so you might need to suck it up and do lecture again. Lab is time-consuming, so your schedule might have bio & ochem lectures on MWF, 3 hr genchem lab on W, 3 hr ochem lab on Tues, 3 hr bio lab on Thurs. It'll be a fulltime load, for sure. Keep your GPA up!!!!
Meanwhile, you'll need to do some volunteering, which you should start now. Go smell some patients and push some stretchers. Be willing to be convinced by your volunteer experience that medicine blows.
The nontrad forum will be useful to you as well. Please keep us posted. Best of luck to you.
