Also, please turn off any script blocking software.


Note: You must take the Journeyman Exam first, even if you're looking to pass your Master's or Administrator's exam. Once you pass the Journeyman exam, you will be permitted to complete the Master's exam.

The test is timed and divided up into sections so you don't have to take the entire test in one sitting. Once you've finished a section you can exit the course and come back later to do another section. Your completed section's scores will be recorded so you'll always know which sections are complete and which sections you have left to do.
