Going to matriculate at ntu this year, planning to take up the 0% interest study loan and repay in full before graduation, before the interest kicks in. Suggestions on where I should put these funds?

It is not feasible to fully repay your study loans with guarantee and safe options like ssb.
I would recommend consolidating your
investment, your cash flow and your goal during and after university

Cash Flow should be your priority in university
Why?
What is your monthly spending? Your annual spending?
What if you need money to buy laptops, projects or oversea exchange?

This includes your dividends from investment and money from external source

Are you free during university?
Do you want to invest during your school term?
Not at all -: passive investing - etf or roboadvisory
Passive-active : dividend - Reits and blue chips
(I assume that you have little time in university and would like to spend more school time)

• Growing your money*
  You mentioned that you want repay your loans by the graduation.
  Is this feasible? What is your total loan? How much more do you need? What is your targeted annual returns? What is your risk vs return profile? What do u need to do to reach that targeted annual returns?
  Is there alternatives for your repayment of loans (psea, partial repayment, etc).

You mentioned that you want to repay fully with a guaranteed and safe option. Honestly, there is no such option unless your capital == your repayment (and you will not have capital loss). You also need to take into account of potential loss (your marginal of safety : your withstanding amount vs your target amount)

Then you need to reorganise your portfolio. Or what roles or purpose do you give to each instrument? Can u maximise further or do you want to withdraw? Do u have better alternatives?
E. G singlife?? E. G etiqa,

After evaluating the above, u can then decide if you should invest into stocks, Reits, robo advisors, etc. Decide between Riskier or safer options

For examples, you can refer to @Pang zhe liang

Singapore Saving Bonds and fixed deposits would be the safest option since they are more liquid and you could withdraw anytime to repay your study loan since you have the intention to repay in full before graduation. I don't think you want to consider other investments since you already have other portfolios.
