While I understand the intent of stating your academic capabilities is not to boast, I am at the same time perturbed that you are still proudly saying such things as evidence that you are smart. You are a 29 year old with quite some years of work experience already; you should theoretically by now have figured out that what you have stated doesn’t matter. In fact chances are the vast majority of people who have exceeded you career wise are not as exam smart as you.

You might have started off with a weak hand in terms of academics having gotten your degree with an unknown lower ranked university, but the work smart people who started out with the same qualifications as you have probably moved way ahead career wise. Career progression is more often determined by work capabilities, office political skills, professional networking and business acumen.

I am not saying all these as a put down, but reading your narrative it gives me a feeling that you seem to think you are a smart guy meant for greater heights who is just let down because of having a non-local degree. Of course the natural conclusion for you is that getting a Masters from a local university is the antidote to solve the current career lethargy. I strongly suspect the reason of your lack of career growth is not that simple. As such, I doubt getting good masters (even if you can) is really going to be a game changer.

On to your 2 options: Getting a business masters or MBA in NUS/NTU might be possible, but after spending a bomb would you really be doing any better than you are now, i.e. drawing 3-4k as a junior associate? I doubt so. NUS/NTU MBA is relatively easy to get as long as you can pay. Students there tend to be mainly PRC and Indians or company sponsored locals (a lot from public sector) who are relatively early in their career and holding positions that are very junior in nature. The more prestigious eMBA or masters may be more useful, but you will not qualify due to lack of academic qualification, work experience and seniority.

I think chances are if you get a msters, you will still end up in some junior analyst or other back office role in a bank that pays around what you are getting now. Of course you can argue it better equips you to get promoted, but I’ve always felt that promotions are much dependent on other real factors than academics. Higher academics make a key difference in highly technical/engineering roles, but have limited value-add in general business analytic in a support department.

As for getting a masters in Monash Malaysia, I strongly advise against that. It isn’t going to put weight into your CV and that’s just throwing good money down the drain. You already have a private bachelor’s certificate, getting another private masters from Malaysia will still rank you behind a local university bachelor grad.
