I used some of the free ones and still managed to pass. As Bruce pointed out the most difficult part was the math and that was mainly because like him I haven’t practiced those skills in over a decade, and it is timed without a calculator. I live in Indy so I didn’t stay at a hotel but there are a few brand new ones within a half mile of the training faculty.

Bruce has a really good write up about it in a previous post and my experience pretty much mimicked his. Good luck!
