Guys and gals, it's easy to find the diagnostic of little use and be upset or bewildered or any other emotion when it comes to not passing. But really, the rules and laws are what they are, and you and the rest of us have to abide by them. You can complain about how unfair it is or whatnot for as long as you'd like, but that's not going to help you pass these exams.
There is a valid point in faster is not better, but these exams are beasts of their own. You need to be able to perform in the testing environment such as it is, which often translates to doing lots and lots of practice problems.
And as for the passing rates, let's wait until they're published to make comments on them, though yes, it's historically accurate that when a new test plan is implemented, for whatever reason, there is typically a dip in the passing rate.
Anyway, you will all get there! It's not impossible. If you thought the test was easy and came away with a poor diagnostic, as useless as it may be in the specifics, it means you didn't correctly solve enough problems for whatever reason. Whether it was a time issue, or any other issue, is at a certain point irrelevant. One should never assume they've passed, until they have the proof that they have. And trust me, everyone can get there!
So keep your heads up and don't give in. Keep at it!
