Okay first relax. I had a double major (bio, chem) in undergrad as well as a spanish minor and played D1 basketball and partied way too much during my four years. I knew my 3.0 (cumulative and science) probably wasn't competitive enough so I enrolled in a 1 year MS program in molecular biology. I put my nose to the proverbial grindstone and ended up with a 4.0 in my MS program that was a total of 30 credit hours. No thesis, just hard as hell graduate classes. Not only will a graduate degree GREATLY increase your chances of being accepted, it will also give you an indication of how you will do in dental school when you have 30+ credit hours of very difficult classes. If you do well, you will likely get into and do well in dental school. If not, you know you aren't cut out for academics at this level and at least you didn't waste any more time and/or money to find out the hard way. There are lots of programs like these out there but they aren't very well publicized so you need to hunt around to find one. I would be willing to bet the UGA or GTech has programs like this and since you are a resident, shouldn't be too costly. The 10K or so that it costs will be a fart in the wind compared to your post dental school debt so its really no big deal. If you really want to get it, I highly reccomend doing so. My 4.0 boosted my overall grades quite a bit and I ended up getting into several schools. Try this approach and I promise you will get in. If you have any more questions about programs like this, feel free to email me. Good luck!
