Mtahs Question & A* Maths Problem Assessment Books by Learning Interactive Pte Ltd

Someone from 6R has posted this question for me and I thought some of you might enjoy a little challenge.

Some of you are interested in getting A* Math Problems by Learning Interactive. From what I've gathered, the books cost around $22 and they're actually 7 thin booklets on 7 different topics in Maths. You can get from Bras Basah on the 4th floor, #04-39. The picture below has been posted by Joslyn way back in April.
