I'm seeking advice. Should I retake some undergraduate science courses, or begin a Master's program to strengthen my application? My problem is that the courses that are closely looked at (General Bio, Gen Chem, Organic and Physics) probably work out to a 2.9/3.0 GPA. My overall undergrad GPA with a bio major is 3.54, and I have since completed an MBA with a 3.9. I have good extracurriculars, good work experience in the pharmaceutical industry (I'm 28 yrs old), and hoping for a 30 on the MCAT. Any thoughts would be welcome.
