Hi, this is the postbac forum. Welcome. I´m afraid this might sound harsh, please be aware that everyone on this forum needed to do something extra for an admission, so don´t take offense or think it´s snobbery.
ANYway, your MCAT is bad and your GPA is terrible. Actually your GPA is so bad that no miracle MCAT is going to get you in until you improve it. What you need to do if you want medical school:
1) Get your GPA up to around a 2.8 by taking more undergraduate courses, I´d guess with science course because your science GPA is not good. This is around the minimum acceptance range for an SMP.
2) Do VERY well on the MCAT. With a 2.8, you´d need at least a 33 for an SMP. If you want to get in with a 30, you need to get your GPA over a 3.0.
3) Do the SMP and ace it.
4) Shadow a DO and get a letter of rec from that Doctor so that you can apply to DO schools. Apply very broadly.
5) Go to medical school.
Your other options:
Mainly, your other option is to improve your GPA through grade replacement, to at least a 3.2 with a similar science GPA, and apply to DO schools. Did you have a very bipolar GPA (Ds and Fs, Bs, and As) with very few science classes? If so this may be a good option for you. Lots of Cs and you were a science major? In that case this might actually take longer than the SMP.
If you can get your GPA to a 3.0 and get your MCAT to a 30 you might also be able to get admitted to the Carribean. Keep in mind, though, that a large portion of the Carib students fail out, and a large portion of what´s left don´t get residencies.
Please keep in mind that the average matriculant for medical school last year had a 3.7, a 31 on the MCAT, and stellar extra cirriculars. The average for Cali residents was even higher. You are trying to convince medical schools that they should take a spot from someone with a 3.7 and a 31 and give it to you instead. This can be a difficult process.
If you´re African American or certain kinds of Latino, this process does get a little easier, BTW.
This is going to be a long and expensive process, I´m sorry to say. You might want to try acing the MCAT just to make sure you can, since that´s the cheaper hurdle, and once you know you can get past it you at least know you can get in. Also, of course, you need to clear up whatever issue got you the 2.6 in the first place. If you really want this, you can do it. Many have before, with stats even worse than yours. Just make sure you understand what you´re getting yourself into.
Dental school is almost as bad, so you know.
Also if your school has a premedical advisor, go talk to him/her.
Good luck, and sorry to be the bearer of bad news.
