Do any of the classes you take transfer to M1? Also you would say this is a very competitive atmosphere? is there much of an advantage to the tufts program rather than just taking UG classes? I already have a 3.4 gpa, but I may need to retake the MCAT.
From what I remember, you can either test out of up to 3 classes per semester or 3 for the whole year. It was brought up at the beginning of the program, and I can't quite remember what was said. If I go to Tufts, I will repeat all of the classes to keep my prep up for the boards, but that is just a personal preference.
The program itself was not easy. As far as I know, only 1 of the 50 people finished with a 4.0. There was a small handful who finished in the 3.9ish range too. I did not find that people were competitive with each other to the point where it became a negative. Everyone obviously wanted to do well, but there wasn't anyone stealing other people's notes etc. I often studied with other people when it was necessary, and was given friends notes if I was forced to miss a class. I thought that for the nature of the program (25% get auto interviews), everyone was pretty friendly.
Doing any SMP program can be an advantage if you do well. It is very hard to move your undergraduate GPA more than a few small percentage points after 4 years of classes. At Tufts, you will definitely be given strong consideration if you do well in the program. They told me that doing a program like this shows that you are really dedicated to getting into medical school.
When I entered the program, I was not going to retake my MCAT. After finishing the first semester, I changed my mind and retook the exam in May. As I stated earlier, all of the people in our program who retook the test saw considerable improvement.
I hope this helps, if you have more questions ask away.
