When do you start your special master's program (specifically for premed students, not a research or MPH or non-prehealth track)? Does this master's program have a direct linkage to a medical school so that good grades from one semester gets you an interview and a possible offer when you are done? Otherwise, you should wait until you can show solid academic performance in the special master's program before submitting an application, especially if you think you can pull a greater MCAT score (which is NOT a major cause for improvement).
