Have not been used before, but external condition is less than ideal. 8/10. By Thomas Pilo Editor: Charmaine Foo-Wong Based on syllabus 2007-2011, so it may be outdated but well history doesn't change does it. Note: All items are for sale until 1st week of September, after which the book will be donated to charity. They will not be thrown away because I believe there will be someone who sees the value of these books. Please do not resell these books. I wish for these books to land in the hands of the people who need it the most.
