Took the test on 9/18 and got the results back on 10/19.
If you pass, which I did, you just get the certificate with your cert number. No test score.
The test is straight forward. As with any test you still have to watch how they word the question.
I would recommend going to the review before the test, it was very helpful.
I know of several questions I got right just from the review, so I would really pay attention.
Just study the info you can print off the MDA website, take your time with every question and you'll do fine.
