GMAT Exam Papers online diagnostic tool for prospective students identifies quantitative strengths and abilities using real GMAT questions and a computer-adaptive process that mimics the GMAT exam. This free GMAT practice test can help by giving you a sense of where you stand with the GMAT. The questions on the CAT do not all count the same toward a student’s score; a correct answer on one question may raise the score much more than a correct answer on another question. As the name suggests, this section contains questions on mathematics. This section begins after an optional (in my opinion,recommended) 10-minute break.
