I think there were about 15, but not very sure. So it would be about 25% of the 60 questions. I remember especially in the start there were quite a few of them clubbed together and it might take a little time getting used to those type of questions. Cause once you click on an 'Exhibit' and after completing it and click next, you will see another 'Exhibit' and you wonder if it is the same question!
Plan on keeping at least 45 minutes for reviewing.
