Having just completed my O, I would like to share what I have
i.e. notes with other singapore students out there. Hence, at an
extremely low cost of $25, you can have the entire set of my emath
notes for your studying reference. With notes for every single
topic, there are tons of worked examples with full yupp, full
worked solutions so you dont have to worry about not being able to
see any explainations when you're stuck and unable to solve the
question(s). Simply cover up the solutions and attempt to solve the
questions. Notes and questions for every single topic, over 250
pages, $25 is, i'm sure to you, is at a bargain. =D
GRAB THEM NOW =D while stock lasts
