These workbooks were specifically created to help a student prepare for the California Achievement Test, 5th Edition (CAT/5) and Survey (CS), but can be used to prepare for any standardized achievement test for those grades. They are made up of all multiple choice questions and cover most of the concepts generally taught in specific subject areas of Reading Comprehension, Language Arts, Vocabulary, Spelling, Math, Science, Social Studies, and Study Skills. Each workbook contains about 40 pages and includes an answer key. The booklets were written by a former homeschooling mother in response to the lack of Test Preparation materials available for Grades 9 through 12.

All test prep books are non-refundable.
