The Quantitative section of the GMAT uses problem solving and data sufficiency questions to gauge the skill level. Quantitative questions require knowledge of the following concepts.
Problem solving questions are designed to test basic mathematical skills and understanding of elementary mathematical concepts, as well as your ability to reason quantitatively, solve quantitative problems and interpret graphic data. The mathematics knowledge required to answer the questions is not more advanced than what is generally taught in higher or secondary school classes.
In problem solving questions, you are asked to solve each problem and select the best of the five answer choices given.
Speed up: Consult the on-screen timer periodically. Work as carefully as possible, but do not spend valuable time checking answers or pondering problems that are difficult.
Read each question carefully to determine what is being asked: For word problems, take one step at a time, reading each sentence carefully and translating the information into equations or other useful mathematical representations.
Scan the answer choices before attempting to answer a question: Scanning the answers can prevent from putting answers in a form that is not given or solving questions by plugging in strategy.
Don’t waste time trying to solve a problems that is too difficult for you. Make your best guess and move on to the next question.
