There is no time limit while you take the quiz. If you can't finish the quiz in one session, that's okay because our server will remember your partially completed quiz for 30 days as long as you are using the same browser and computer. However, you must complete the quiz within one year from the date of purchase.

This could be caused by one of the following reasons:

1. Your computer's resource is low. In other words, you may have several applications running, and your computer may not have sufficient RAM to open another PDF document. In this case, we recommend that you first save the file to your computer by right-clicking the mouse, choosing "Save Target As..." in Internet Explorer or "Save Link As..." in Chrome or Edge, and then opening the file in Adobe Acrobat Reader.

2. You may not have Adobe Acrobat Reader installed on your computer or you may have an earlier version. Please click the button below to download the latest FREE version of Acrobat Reader.

Occasionally, our server may miss communication from our payment gateway. If you cannot access the quiz or course materials after online payment, please notify us through "Contact Us" or call us at 571-295-4410. Once we receive your notification, we will activate the quiz or course for you, and send you an email confirmation about the quiz or course activation.

It depends.

For regular online courses, you may print the course materials and study them offline, at your own pace.

For live webinars, you need to be on the Internet or the audio line the entire time of the webinar session.

Yes. As a matter of fact, you may access your courses using any computer or smartphone from anywhere around the world.
