Just got home from taking REG, I got knocked around for 4 hours with that test. On half of the questions, I sat there in my chair debating and arguing with myself if it was a trick question or not, they tested just about every major topic that REG covers, by the end of the exam I was uncertain of just about every tax and business law principle there is and upon walking out of the test center when it was done – I felt as if I never studied for the exam at all. However, the test questions were fairly simple, very little calculation was needed, and the Research and SIMs were not that bad. I only had 3 weeks to study due to the 1st Quarter test window closing, just enough time to read the 500-page book and watch half of the videos, I didn't do any SIMs or MCQs at home, so I need to spend 7 weeks doing that at home and then going back in early May to take it again.
