I have the Gleim sims. I used to post about this quite a bit, but I switched over to Gleim from Roger after passing my first two exams because I “barely passed.” I wanted to feel more prepared for REG and FAR and thought Gleim could help me do that. Long story short, I failed REG twice in a row because I wasn't really benefiting from the Gleim MCQ. I went back to Roger for lectures and combination of Roger and NINJA MCQ.
However, as far as the sims, I still practiced some of the Gleim sims before I took REG. I don't know if it was luck or being better prepared but I had two sims that were almost identically set up to a couple that I had practiced in Gleim. Even though I didn't practice a ton of the Gleim sims, I certainly felt more prepared for the sims because of using it.
For REG, I felt like the Gleim sims were comparable in difficulty to the real exam. It remains to be seen for FAR. I just tried to do some Gleim sims but didn't get through much. I am probably going to practice as many as I can during the last 7-10 days before my test
AUD- 71,79
BEC- 72,77
FAR- 83
REG- 63,71,83
DONE!
