I know you are asking the teacher, but incase you didn't know the regular test can only be taken at LCC & Community Learning Centers, the Practice one is the only one available from your home computer. Maybe you already did that, but I thought I would mention just in case. By the way, other "practice" tests on the E&Z site are helpful (both Multiple Choice & True/False) to test your skills for future reference. :)
