Why is he not giving you household income? (: Anyway gently prod him. Guys sometimes mature when they take on responsibilities. Paying rent, being forced to budget, plan for future HDB purchase with gf, etc.

Get the degree. usually the returns from better job, assuming a $500 monthly increase (can be more) that is 6,000 a year. is much more than the interests from the debt. The other important thing is do it while you are young. More energy, less commitments. My friends and I are at the stage where we don't have much time anymore. Haha. 35+ yrs in case you are wondering. edited: I do think there i benefit in working for 1-2 years so that you can see the real world and how degree can benefit you in your area of work as well as helps you to appreciate the knowledge imparted during your degree course more. (:

Unless your family is rich, it does not make much sense to start investing now. I used to be very frugal and not from rich family and I only managed to save up around 12K+ during my uni days. Even if you get a 20% returns (highly unlikely), it is still only 2.4K a year, assuming you even have that money and will put every dollar in. The best investment is to invest in yourself, your studies, your career. To provide a perspective, depending on your grades and course of study, the difference in salary can be 1-2K that becomes 12-24K a year, much more than you can get out of investing currently. An advantage to investing now will be for financial literacy, so it is ok if you want to start early to familiarise yourself, but do spend more effort on your work.

Talk to your friends in finance or invest. I have a whatsapp chat group with my sec sch friends that I sometimes use to ask finance stuffs. No vested interest for them to give biased advice this way.

I wouldn't buy a luxury phone for my children. I will ask him to either 1. use it with cracked screen. 2. pay it with his bank savings.

I haven't used DBS Multiplier, from what I understand, it doesn't require one to spend huge amounts on the credit card. As long as the Salary credited monthly is 2,000. And maybe use your DBS cc for 1 purchase. That will get you near to max returns. It makes sense to me actually to charge to other credit cards to optimise returns.

When I was 26, I take home around 3,000 every month, I saved 2,000.
