A study guide for the 3rd and 4th grade Biological Classification Skills Certification Exam. This is a collection of past exam questions. Although the exam format has now changed to a computer-based test, the types of questions haven't changed much. I think you can pass if you study this book. Two pages of illustrations (photo pages) are missing. I will insert them and send them to you. - Title: Biological Classification Skills Certification Exam 3rd & 4th Grade Study Guide - Publisher: Nature Conservation Research Center #BiologicalClassificationSkillsCertificationExam #PastExamQuestions #StudyGuide #Biology Thank you for looking.
