You can get a one-year pre-med certificate in 6 different subject areas and then continue for one more year to get your masters if you choose to do so.
I don't know the age of the others, but BU's Master in Medical Science started in 1986, and has an excellent success rate at getting people in allopathic school in the U.S. (near 90%). It is also a good springboard for dental, osteopathic med, nursing, MPH, etc.
