Gotcha! That really helps, thank you so much and I am just taking it because I am trying my best to see if I could possibly do without the glide year? I don't want to be two years behind applying if i'm being completely honest.
Two things:
1) You're not behind by waiting two years to apply. I get the wanting to get to med school ASAP part (I did as well--we all did), but the average age of med students is going up. I'd argue you'll be a better med student and a happier person with a little more experience in the world (ie., by working near/full-time in that 1-2 glide years). Back when I was a post-bac, I wished I could get to med school ASAP. Now, I wish I had taken more time and done either the Peace Corps, joined the military, or done some other big service like that.
2) Your application will be
significantly stronger if you wait until you're ready--both to take the MCAT and when you're overall ready to apply (ie., all your post-bac grades are in). A bad MCAT score can/will tank your application, though some schools look at the best performance. A low GPA will also tank an application. It's typically recommended to apply when you're ready to put your best foot forward because it gets harder to get accepted if you re-apply. There are other threads that go into the whole re-applicant thing.
Unfortunately, to do things right (particularly when like me you have a low GPA to content with), you really should be as patient as possible. Get all A's in your post-bac coursework, and by getting A's in those pre-reqs, you're essentially studying what you need for the MCAT. I lightly reviewed bio/physics/o-chem (the courses I took in my first year as a post-bac) for a couple weeks, and reviewed gen chem more intensively (I took that prior, and didn't get an A). I was happy with my test scores, and I took the test when I felt ready. I had also been intensely participating in two quality volunteer jobs as well as working-part time as a case manager, which was also great experience. Then I submitted my application and hoped for the best, knowing that I had done everything I could to boost my application as best as possible.
Glide years are truly a blessing. You can do whatever you want during that year. If you have money saved up, travel! If not (like me!), get a job and see what the real world is like--you'll appreciate your job in medicine all that much more.
Ultimately it's up to you to decide what's best for you. But I'd recommend considering the above, and if you opt to push forward quicker, try talking with people who have done that. Just keep in mind with your GPA you really need to prove yourself, and the question to ask is if you'll have done that by the time your application is submitted.
