Hello my friend! If you can afford to go full-time, and if you are younger than 35 or so, you should go for a full-time MBA program. After all, that is the way you will get the most out of the program—contacts, courses, and even credibility. The other programs (part time, executive etc.) are all great—but only for folks who tend to be older, or who cannot afford to take two full years to attend school. I did my MBA at HBS, and it was full-time. In fact, HBS doesn’t offer any other kind of MBA degree... So if you are younger than 35 and can afford to, only look at full-time programs. Those will be the best value for you for sure
