I’ve been thinking about the cost of education in Singapore and would like some advice or feedback.

I think the key is to saving first and investing. Explore all options like CDAs, low risk bonds, medium risk equities, and hedge according to your needs. If you are younger, you can take more risks. As you become older, you should invest more in safer instruments. There are a few places where a Singaporean can save money. Buying regular food instead of organic, buying house brands instead of branded stuff when it comes to food and clothing, using public transport instead of Uber, all save a dollar here and there. However, at the end of the month, you might end up saving a couple of hundreds. Like said earlier, don't save what remains at the end of the month. Try putting aside money for savings first and try to manage in the remaining. Use cash instead of cards when shopping. You tend to spend less when you pay with actual money instead of tapping a card. Hope this helps
