Have a Code from Our OLD Site?

Usernames and Passcodes from our OLD website
will not work here.  But we have converted them.

If you have a valid, non-expired course UserID and passcode from our OLD website, it will not work on our NEW website.

We converted old (legacy) UserID/passcode combinations to become course voucher codes.  If you purchased your courses from our old site after Sep 1, 2020, follow the following instructions:

  • Visit our Classes Page.
  • In Section A of the page, add your class to the shopping cart.
  • Use your old UserID and Passcode (separated by a dash) as a coupon code to enroll in the class at 100% off.
    ( Example: RAD5124-A33KJ3M )
  • Click on Course Login and take your class.

If you purchased from our old site prior to Sep 1, 2020 and have not completed your course, use the form below to retrieve a new course voucher code.

We will replace it at no cost.

Still Having Trouble Using an Old Code?

Send us your old code.  We’ll send you a new one.

If you have a valid, non-expired course UserID and passcode from our OLD website and the course voucher conversion above does not work for you, simply provide your name, email address, and UserID/passcode combination in the form below, and we will send you a replacement code for course enrollment.
