Recommended Assessment Books

I have received some emails from parents regarding Science and Math assessment books. These are some that I recommend:

Maths
1) Improve Your Mathematics 6 (Andrew Er)
2) A* Maths Problems (Learning Interactive) (www.li.com.sg)

Science
1) Challenging Science P6 by Janet Sim (Educational Publishing House Pte Ltd)
2) P6 Ace Science Explorer by Joyce Lim and Tan Li Ling
3) Science Companion P6 (Educational Publishing House Pte Ltd)

My maths weekly questions are from (2). But it's hard to get and rather expensive. I got it from NIE last year.

Please also take note that Science assessment books are never perfect. The good ones are only 50-60% good.
