Chem 2 NCEA Level 2 Workbook

By | Copyright Year:2014 | ISBN-13: 9780170260107

Published:26/09/2013
Chem 2 summarises all of NCEA Level 2 Chemistry. It includes full theory, practical work and exam questions for each external standard and brief outlines with important notes for each internal standard. Chem 2 also includes fully worked examples so students can see how to work to an Excellence level, whilst also including Nature of Science literacy tasks. Finally, to help students prepare for their external examinations, there is a practice assessment of each standard with a Grade Score Marking schedule.
