SG education system actually " go by trend " which industries will be the next big thing they will focus on it but end up reality don't seem workable.

Look early 2000 focus on IT , as after IT bubble burst in late 90s , later IT sector regain fast, later early 2000 , come what " Life science " than later nursing , now learn to be " modern farmer " using technology, also back to IT

you can see they go by " trend " which industries will be next big thing .
To me , NEVER chase trend.  End of the day.

Yea, actually you've touched on the curx of the issue. The schools are always supplying seats for courses based on what is the CURRENT demand and supply situation. The problem is they plan their cohort and determine the seats 1 - 2 years before intake, then the students spend another 3 - 4 years studying and graduating.

By the time the planned cohort of students reach the labour market, it's already ~5 years since the courses were planned. That's why there's always a shortage and surplus of the people with the wrong qualification for the market. This problem has happened multiple times in the past decades already:

1) Late 80s early 90s - Electrical Engineering
2) Early - mid 90s - IT
3) Late 90s - early 2000 - Internet
4) Early 2000 - 2008 - Banking & Finance
5) Late 2000s - Mid 2010s - Biotech / Life Science
6) Late 2010s - Present - AI / Big Data / VR 

I always tell youngsters who are thinking of choosing course to study based on what is the current trend NEVER to do that. What you can see as hot is now, what is hot when you actually finish study and look for jobs is completely different. The worst is Singapore males, you choose your university course at 18, by the time you finish and look for job already 25.

Nowadays I still see many CVs of youngsters studying Biotech and Life Science during the mid 2010s applying for jobs that have nothing to do with this so called super hot industry in the past. When I asked them why are they applying for or ended up with their first job in places like Marketing, HR, PR, Events etc. the most common answer is way too little openings in these areas and too many people of the same cohort fighting for it.
