GIGI Pro Certified has several security features designed to maintain the integrity of our membership.

Each test session loads questions randomly from a large database so multiple attempts have minimal repetition.

In addition, Pro Certified has a nominal test entry fee designed to curtail multiple attempts and allow for name verification through the cardholder's name.
