The pass rate is very high, due to the curve on the exam. The test is created so that if you've attended class you will be able to pass. To do well, however, is another matter. It is difficult to do really well.
So, if you simply want to pass you shouldn't have any trouble at all. For example, on some sections you only need to get 30-40 questions correct out of 100 to pass (a scaled score of 75 is a pass).
To get a 95 on that same section, however, would probably require you to get 90-93 questions correct.
