Well, this question has been asked so many times in this forum. Hmmm...what can I say? As a Sound Designer and Audio Engineer, I would like to advice you and everyone that there is no point spending so much money studying this topic "Audio Engineering".
First of all, you've got to face the reality that Singapore market is still small and not established yet. Hence, the consequences of taking such courses is that you might end up jobless UNLESS you got the contacts, OR you willing to work late in pubs. Singapore is more about live sound reinforcement. If you think you could easily & comfortably get a sit in a local recording studio, I'm sorry dude....most studio owners are engineer themselves, why would they even need you? If you are thinking of setting up your own, think again. Do you have contacts to get constant reveune? How many studio already are there in the market currently? Do you think you will have a share of the pie in this small island rite now?
Secondly, even if you have a Degree or PHD in it, people in this industry generally don't really give a damn to all these cert. thingy. You need strong experience, skills, and port-folio than a worthless cert. Why is that so? Here is the main point. "Audio Engineering" typically has got nothing much that you can really go and "study" it. All you need to know is the the operational skills of the equipments found in a typical studio, and understanding what are each of their role, and when to use this and when to use that. Apparently, all these can be learnt by yourself, either from friends, books, online research, library research, or spend a little buying one or two equipments to explore them yourself. Don't start buying expensive pieces of course. Start with cheapo ones first. When you finally understand them and know what electronic is for what purpose, then you will need to ask yourself what kinda of work will you be doing. From there, then you slowly start buying the necessary stuffs.
Other than all the above that I've mentioned, which are generally technical side and operational skills, the rest and the most important part of the Audio Engineering is simply your EAR, where nobody can teach you that. Be it SAE or government Polytechnics, etc., they simply can't teach you that. This can only be mastered through many years of non-stop practices and experiences to obtain it. And this is where you guys should be spending your time and money in, rather than wasting them in getting a unless cert.
Of course, if you are planning to do composing and arranging, then Audio Engineering should not be the topic that you should look so much into. You should look more into the musical aspects then.
