Any1 have a personal opinion through experience as to what 2u math topic is hardest and is simplified through the 3u course?

Probability.

I never learnt how to draw a tree diagram, so the binomial work I did in 3-unit and 4-unit was a definite help.

Never learnt the superannuation stuff because I knew I was definitely going to keep 4U.
