We have received the following (albeit short) feedback from one of our students. He used our old exam simulator and then scheduled his exam AFTER the change without realizing that he was going to take the new exam. He passed. I asked him for feedback and he said the following:
"prepcast was my only study tool and it was close enough"
Based on this (single) feedback, we are now more certain that our current simulator (for the old exam) is still valuable for the new exam. But obviously, we are still reviewing and updating all our questions, so that the simulator matches the new exam better. For now, however, we only have the old version available, which is "close enough".
