I was getting like 50 of 60 on practice BarBri. Scored 141. Not sure how many I got right on real exam. I think the BarBri video said mid 30's is needed on average to get an 85 (score I needed), because it is a curved score. I studied about 25hrs for it, and in hindsight probably 15 hrs is plenty if you did decent in PR. If you were below the curve in your PR class, then I would suggest more studying.
