Bundles are sold as discounted items with their own product numbers (different from the individual items which make up a bundle). Individual items purchased separately over a period of time are not eligible for the discounted bundle prices.

If you are not completely satisfied with your purchase, we will gladly help you with an exchange, credit, or refund. Return information is attached to every packing slip.

We do not claim that our materials match up exactly to each test or teach all the skills measured in a particular assessment. The recommendations made here are determined by The Critical Thinking Co.™ and are not endorsed or certified by the author or publisher of each test. The contents of these bundles were determined by The Critical Thinking Co.™ and have not been reviewed by, nor are they endorsed, sponsored or approved by either the author or publisher of the tests. While the recommended items will help prepare students to master the skills tested, they do not reflect the actual test items on any given test.
