Your going to need to do extremely well on your DAT's and have tons of extracurricular activities to explain the lack of g.p.a. If you don't have the g.p.a. for it, it is best to join a PB Program to improve your g.p.a. If you did bad the first 2 years of your college history and great the last 2 years, the admissions will take that into consideration as well.
