How To Study and Take Tests

This is a must for all test takers! This guidebook includes proven methods, and material you would normally be furnished via a course on study skills and test taking preparations.

This guidebook, coupled with your HDEL study products, should provide you the advantage you need for any competition based promotion or exam requirement.

HDEL products are prepared for test preparation only and are NOT intended to be used in group study or on the job. Be sure to begin your study process early enough to cover all the information in your WAPS PDG Self Study Guide and SKT Self Study References.

Remember to begin your studies early enough that you learn all of the information on the exam. HDEL recommends that you begin your studies 6 months in advance of your test.
