"I found that quickly scanning the data first, then reading the questions carefully, and then going back to the data and carefully analyzing the relevant section ... to be more effective," she says.

5. Practice at your ability level: Laurence Lau, an analyst at a financial services company in New York, recently took the GMAT for the second time, so he has experienced both the old and new versions of the exam.
Applicants studying for the test should practice GMAT problems "at their ability level," advises Lau, an alumnus of Carnegie Mellon University.
"If you are scoring 550 on practice exams, doing 700+ level questions isn't going to help you, because you'll never see those questions on test day," he says. "You need to master the 500- and 600-level questions first."
He also recommends that students avoid the folly of only reviewing their incorrect answers to practice questions. "I would tell people to also review all of the correct answers, why your answer is correct, and why the other answers are incorrect," he says. "This may not help as much for the quantitative section, but it helps immensely for the verbal section."
