The problem solving section is a part of GMAT MATHS section. The other section is data sufficiency. In the problem solving section, you have to solve around 10 to 12 questions. For each question, you should not take mote than one and a half minute. These questions will cover various topics like geometry, time-speed and distance, time and work, averages, ratio and proportion and also mensuration. Thus, you have to be well versed with all these topics.

As far as the questions are concerned, they will not be very tough. It will be simple, but the most important thing to be kept in mind is the time efficiency. You have to be accurate and maintain the time too. There will be options after every question. You have to tick the right option and then, move ahead to the next question.

Very importantly, you should not panic, in the problem solving questions. There will be many other questions, to attempt in case you get stuck on one sum. You should not take more than three to four lines to write and get the solution. You should use a rough paper to make the solutions.

No calculator will be provided for the exam. Thus, you have to be very accurate with the calculations. Apart from that, you should know the simple things, like the tables, % equivalents of 2 to 10. Square roots of 2 to 10 and also the squares of 1 to 30 is important. Again, the tables from 1 to atleast 30 should be learned by heart. All of these will help a lot during calculations. After all, time management is the key. All the numbers will be real numbers, so there is no need to go beyond them. Imaginary numbers will not be asked. Another important point to remember in case of problem solving is that you should learn the shortcut methods for multiplication and squaring. This will also save time.
