I have gone into detail in the past, so you can search through my comment history.
But essentially I had a 3.1 GPA going into dental school. I had to take classes at a local community college after I graduated from college -- then I re-took my DAT (Brought it up from an 18 AA to a 24 AA) --- then got my Masters in Biomedical Sciences to increase my GPA and prove I could handle Grad level courses -- then applied. Even with all that work, I only got 2 interviews... and 2 acceptances <-- a month or so after the December Acceptance date.
So it's definitely possible but it will be a lot of work! I am now heading into my Spring semester of my D3 year. You can do it!
