I'm a graduating uni student that has a DBS student loan. May I know how can I find ways to grow my wealth i.e. how and where do i invest so that I can pay off the loan asap before getting a BTO flat?

Your income would be the main source of your repayment for the loan, which should be your priority rather than investing into high risk products. It might take some time to fully pay off the amount, but surely you will get there so don't give yourself too much pressure. If you think your parents might be able to lend you a lump sum, have a talk with them and work out a plan on how you will pay them back this amount over a couple of years.

I would suggest paying off your loan asap before you even attempt to start to invest. This is because all investment have risk and i'm sure you do not want to delay your loans just because you have put too much money into investment and it is not making and profit.
