Sorry to hear that. don't be too disillusioned though, this happens to a lot of people (even i struggled when i was doing a research module in nus in year 3, almost got depressed)

one way to get through this is to focus on the project work you did and make the employer understand you were more of a practical person and that you flourished in practical, project based modules...

There is a big focus on sincerity and goodness among good hiring managers, it is ok to be sincere and highlight what happened.

Of course if you are up against those typical local old school type hiring managers (which GLC's and stat boards are full of), then you are out of luck

they are the bane of the job market and the faster they retire/get out, the more pleasant working in SG will become
