Some key things you should be aware of regarding the new version of the test:
- As you are likely aware, Sentence Correction is completely gone from the test.
- Geometry is mostly gone, but contrary to what you may have heard, some Quant questions can still involve basic Geometry concepts, such as calculation of the areas of shapes, the number of edges of a cube, and the Pythagorean theorem. Also, some aspects of Coordinate Geometry can still be involved in GMAT questions.
- Other major changes to the test are in Data Sufficiency questions. One big change is that, on the new test, around half of DS questions can be Verbal questions. So, to be prepared for the test, you need to be ready to answer Verbal DS questions, which do not appear in the version of the OG that you have. Also, there's a change to math-based DS questions as well. There are no more pure math DS questions, the types that involve only mathematical facts or variables. All DS questions involve real-world scenarios. So, the math-based DS questions are all in the form of word problems.
- Also, it's good to be aware of some key aspects of scoring of the new test.
One is that the Quant scoring is pretty tough. No longer can you get a top Quant score with several missed questions. Now, just a few missed medium questions can drop your score 10 points.
Another is that the penalty for unanswered questions is now larger. One unanswered question can ding your section score by 3 or 4 points and your total score by 20 to 30 points. So, be sure to mark and confirm your answer to every question.
Overall, the new version of the test is pretty cool, and it seems more relevant to business school than the previous version. So, preparing for it is worthwhile not only because it will help you get into business schools but also because it will result in your developing skills that will serve you well going forward.
