OMS-1 here
Remember, the committee will look at your overall package you provided.
What are your hours of service? LORs? hours of shadowing?
Personally, I didn't go the master route. Here's why:
1) Classes are harder.
2) Not all students who did a master program will get accepted
3) Expensive...... Double lost here-- wasted money on master program and didn't get accepted.
If you have the cash, then go for it.
I retook a bunch of classes and boosted my GPA at the fraction of the cost of a master's program.
I would say my stats are relatively similar to yours, but I had other factors on my application to compensate my weak spots.
