How to score 50/51 in GMAT Quant Section

In GMAT quant section, a score of 50/51 out of 60 is rare. Even students with maths background struggle to get high score on GMAT quant section. The most common reasons for low score in quant section are

  1. Lack of Knowledge
  2. Wrong Approach
  3. Calculation errors or silly mistakes

Let’s take each reason and understand how we can overcome these problems


If we observe most official questions in official guides and official mock tests, GMAT rarely gives a question that requires in-depth knowledge of any particular topic. Most questions in GMAT quant section require basic knowledge of each topic.

The best ways to acquire basic knowledge about topics tested in GMAT quant sections are

  1. School books
  2. Books published by GMAT prep companies
  3. Online video course by GMAT prep companies
  4. Group coaching conducted by GMAT prep companies
  5. Youtube videos
  6. Hire a GMAT private tutor

Always take one concept at a time, master that concept and then move on to the next concept. Most students have a tendency to move to next concept without mastering the current concept.


Approach is the most important factor that determines the score of a student in the GMAT exam. The most common approaches to solve a question in GMAT quant section are

  1. Substitution: We substitute values for variables give in the question
  2. Apply concept/formula or solve equations
  3. Work with answer choices

Mostly during the exam, when a student starts a question, he will read the question and starts solving the question with the first approach that comes to his mind. It is called reacting to the situations. This is a trap. A better way is to read the question and then think what the best approach for that particular question is.

Also, in case you begin to solve a question and get struck in between while solving the question, simply change your approach to solve the question. For example, if you start to solve a question with substitution approach and you get struck in between, immediately switch to other approach i.e. try to apply some formula or try to work with answer choices. Avoid attempting same question with same approach again and again.

Calculation errors or silly mistakes

Most questions in GMAT quant section do not involve in-depth calculations. Most questions involve basic calculations. Most students have a habit on noting down everything given in the question on the paper. When we note down everything on the paper, we lose contact with the question because we read a part of the question on the screen, then note down the information we read on the paper and then go back to the screen to read the next part of the question and then again we note down the information. While repeating this process, we lose contact with question many times. This process breaks our thought process that starts once we start reading the question. This switching also deviate our mind to other things such as clock, thoughts about the score etc. In simple word, we lose our focus and we start making silly mistakes or calculation errors.

If we read complete question on the screen, we will have a continuous stream of thoughts and in maximum questions we may not need to write anything to solve the question. This approach will save time and we will not make silly mistakes or calculation errors because our mind will be complete focused on the screen rather than thinking about other things.
