This is just me talking to myself… With paper 1 over, seems like this time round, the paper is slightly imbalanced. Questions that were too easy at the front, and last three became rather [...]

After teaching H2 Mathematics for so many years and sharing my suggested solutions post A-levels, I thought I collate them nicely and type them all neatly here in LaTeX. 🙂 Please be kind to be [...]

Let us look at the difference between modal value and expected value. We shall start by saying they are different, albeit close. Modal value refers to the mode, that is, the value that has the [...]

I want to share a question that is really old (older than me, actually). It is from the June 1972 paper. As most students know, Maclaurin’s series was tested in last year A’levels [...]

I was teaching scatter diagram to some of my students the other day. A few of them are a bit confused with correlation and causation. I gave them the typical ice cream and murder rates example, [...]
