Yes - both Maths and Verbal have unscored questions. If you did PP3 and reviewed the questions before, you would have seen that only 28-29 maths questions and 30-31 verbal questions were actually scored. But it is hard to tell which the unscored questions are in the real exam situations. Make sure you get the first 10-20 questions as correctly as possible. But of course, you need to pay attention to all the questions as well.
