Yeah I agree with the above post. I was in your situation too...I had a 2.5 gpa after my freshman year but brought it up to a 3.5 by the time I graduated. I obviously applied the summer after I graduated in order to include my senior grades which pulled my gpa from around 3.3 to 3.5 my senior year. This will probably be the only option for you since you are ending your sophomore year because there is no way you will be going from a 2.7 to a 3.4 in one year. So plan on applying after your senior year which will force you to take a year off after graduation. If your gpa is still not where it needs to be, a postbac may be needed. Taking a year off can be great because not only do you get to rejuvenate before med school, but you also get to add another full year of extracurriculars, community service, research, and leadership positions during your senior year. Good luck.
