The GRE was significantly overhauled in August 2011, resulting in an exam that is not adaptive on a question-by-question basis, but rather by section, so that the performance on the first verbal and math sections determine the difficulty of the second sections presented. Overall, the test retained the sections and many of the question types from its predecessor, but the scoring scale was changed to a 130 to 170 scale (from a 200 to 800 scale)
