Thanks for the guys who respond my question regarding the enrolment key issue of moodle test. I thought that I should brief this forum in case anyone might search for the same problem.

If you try to take the test but you are asked to enter an enrolment key, it is the student center's mistake. It means that they haven't still sign you up to the test. Contact the student center immediately via e-mail and they will make the situation right.

Wish all of you the best. Good luck.

i got a quesiton to the guys who took the moodle test. i tried to take the test but apparently i can't access it. i was told that i should take the industrial engineering and managament/design and engineering curriculum test, but when i try to enter, an enrolment key was wanted. anyone know anything about this situation?
