Jane, we can see that Sec 2 Maths concepts are quite different from Pri 5 and Pri 6 Maths concepts apart from a few percentage, decimal and rounding off ideas. It’s mostly algebra now.

If you recall, AC Lim and many other tutors have helped you since the primary levels and you can see the development of the maths subjects over time.

Remember that primary school covers lots of ratio, fraction etc?

Now that it’s secondary education, it’s largely centred around algebraic expressions.
