What is the best invesment portfolio as an NSF that will go into university next year?

Yes like what ATJY said, AIA pro achiever is actually an ILP. You should talk to your financial advisor about it as i really don't recommend someone buying an ILP due to its high costs. They will charge you around 2.5% per annum just to help manage the fund. Additionally, the money is being locked up too.

If you are new to investments, you can try out robo advisors like stashaway or syfe. They will help you diversify your portfolio at a low cost!

Additonally, if you are more adventurous, you can also invest in ETFs on your own. Do use the regular savings plan option in FSMone to adopt dollar cost averaging. If you need the referral for stashaway so we can both get 6 months free management, do let me know!

ILPs are generally not worth it if as compared to passive investing in an ETF. I personally agree with Frankie's answer (his article is long, but please read and understand what he wishes to convey) so you can then digest and decide if you wish to continue with the ILP.
