If you're paying RM300k for an MBA it better be from a top b-school ie. Harvard, Stanford, INSEAD, Columbia, Kellogg, Wharton, LBS. If it's not one on this list then you're wasting your money.
If you're paying your whole MBA yourself then you're not thinking strategically. Scholarships and loans will open up to you once you've been accepted to any of those schools above which can cut down the cost by a fair bit. From personal experience you need the initial 20% and the rest are covered by scholarships and loans.
The key is to get accepted to one of those top schools. This is the most difficult step. Once accepted, your options open up. To get accepted you need to:
1. demonstrate that you're successful enough in the 2-3 years work experience that you have, plus you fit the profile that these schools want
2. do GMAT, write the application essays, get recommendations
3. apply! There's an application fee but that's the only fee you have to pay up front.
If you're not accepted, you can try again the year after if you can figure out what you did wrong. Alternatively save the RM300k and start a business or buy a house or ... Paying RM300k for a no-name MBA is not very prudent.
I'm speaking from personal experience, I was accepted and joined one of those schools above, spent about RM300k as well and my ROI is less than 2 years.
I'm planning to join one of the top 20 schools listed in FT. I'm just preparing for the worst just in case couldn't get any scholarships. Mind telling me which school you went to ? What's your degree and where did you study for your undergraduate ? What was your GMAT score ? What was your CGPA for your degree ? Where did you work for the 2 to 3 years ? If you're not convenient to say it here, please PM me. I'm very eager to know. Thanks!
