After some research, these are some of the 9 key factors I would take into consideration when choosing my post graduate school.
1) Reputation – I don’t want to be ashamed of your school appearing on your cv
2) Duration of course – opportunity cost of doing a part time or full time course on impact on my work/career/cash inflow
3) Budget – how much spare cash do I have and how much loan am I willing to take
4) Faculty – to build a strong network and learn from the best
5) Curriculum – the name of the cert can be good but the contents crap?
6) Student Profile – how much are the students similar to my own values, are they of someone I aspire to be, which are the sectors and positions they go into after grad
7) Years of establishment – definitely one factor to build a strong legacy and good reputation
8) Facilities – do they have sports facilities, location of school, flexibility?
9) Staff – are they friendly and helpful to students?
First thing first, take GMAT!
