I think part time and full time programs offer completely different experiences. Some of the considerations I can think of are
- Can you see yourself working and studying at the same time?
- Do you want to leverage the MBA for a career change. If so can a part time MBA achieve it?
- Do you want a break to reflect and work out what you want to do in the future?
- How tight will the network be in a PT MBA compared with a FT MBA (open ended question, I have no idea)
- There may be a perception by employers that part time programs are not seen as an equal to full time programs
- How important is the social aspect of the MBA? Clubs / trips etc
It comes down to what type of experience you want and how risk adverse you are. The part time option would keep you employed and your finances will look a lot healthier but will it achieve what you want to do with the MBA. The loans of the FT option are daunting but if it gives you a better shot at what you want in the long term then it may be worth the risk.
