About iCertify

iCertify is a set of flash cards for Apple's iPhone, iPod touch, and iPad. The flash cards will help you pass Cisco's 640-802 CCNA® exam to become a Cisco Certified Network Associate. iCertify features almost 300 flash cards. The cards pose a question and then give you time to answer.

iCertify was used by the author, Priscilla Oppenheimer, as her own study guide when she renewed her CCNA certification. Her flash cards are an easy and fun way to learn and test your knowledge.

Priscilla is a well-known author and educator with strong integrity and pedagogical principles. She won't provide actual test questions or help you cheat. But she will provide well-written questions and free updates as she adds new questions to the iCertify app.
