The Experimental Programme

In order to know if my homeschool program is in line with the local nursery schools, i purchased a set of their 'textbooks' and 'assesment' books (including mandarin). These books are apparantly used by the school teachers. I wanted to use these books as a guidance to my homeschool program. But, when i flipped through the pages, i realised N already knows most of it- including the Mandarin books. Not to let my money go to waste, i decided to use them as revision instead!
