No a bar exam appeal does not mean you go to court. I have done a few bar exam appeals and have acheived as many as 9 extra points for a failed bar examinee. But, when do these appeals the trick is how substantial the test takers answer was? Can you make an argument based on the test taker's answer that will get the appeal reviewers attention enough to give extra points? Its all based on how substantial the test takers answer originally was, and how creative you as the advocate can be. But the process has nothing to do with court. You appeal consists of explaining the answers of the test taker and providing support for you interpretation of that answer. I have heard stories of people acheiving 15 or more points on appeal, but have not seen it first hand. And, it is, I suppose possible. You have to remember that the persons grading your original answers are busy lawyers that read the examine over breakfast, over lunch or throughout their day and they have dozens to go through, so mistakes are not only possible, but probable. The level of mistakes just depends on the individual that is grading your particular question and how much attention they pay to detail.
