first time I applied my gpa was very low. I had around a 3.0 sci and 3.3 overall. My TS DAT was alright, but each time I bombed one section. The first time I bombed chem with a 16, the next time, I bombed orgo with a 15. Since my grades for these courses were both C's, I completely understand why I didn't get in. I had alot of EC's, good letters, and my sister and father are both dentists but that obviously is not enough. I did a masters program, heavily concentrated in research, published as a co-author in a reputable journal, and studied like mad for the DATS. My grad gpa is a 3.5, I TA'ed for Gen Bio and Adv Cell Bio lab, brought my TS DAT to a 23. I also work as a dental assistant, starting after the first time I applied. Hope that helps!
