GRE 2018 new pattern
The main reason for this kind of questions is that the examination authority first tests the new questions via the unscored questions, they research the questions, and the questions that they feel are good enough, they would include in the scored question. The candidate would get no notification from which the scored section ends and from where the unscored ones start. For download paper pattern for GRE visit the official website.
