Posted on: Mar 22, 2024

Preparing for the GMAT is demanding and challenging as it differs from other tests. It is a hard exam, and it is easy to make mistakes while preparing until one writes the exam. Meanwhile, a strong score can significantly boost one’s chances of attending top business schools worldwide. This article focuses on the most common mistakes students can make while preparing for the GMAT exam and provides tips on avoiding them. 

 

Top common mistakes to avoid the GMAT exam 

 

  1. Cramming 

Students often need help as they make the most common mistake of trying to complete all the GMAT preparation in the last few weeks before the exam. The GMAT exam requires a lot of time, routine and planning for study. The students should study for at least 10 hours a week over several months. They should also plan for at least three months of learning when they create their GMAT preparation schedule. 

 

  1. Not using the computerised adaptive practice test 

The most common mistake the GMAT test takers make is not using computerised adaptive practice tests. Students must simulate GMAT exam conditions during their study sessions. Engaging in practice tests in the exact format of the actual exam helps determine an ideal score. Preparation books also offer comprehensive explanations of each section and effective test-taking strategies.

 

  1. Studying without a plan 

Some test takers continue to take practice tests after practice tests and think this is enough to improve their GMAT scores. However, this approach often leads to repetitive mistakes without any progress. Adequate GMAT preparation requires a personalised focus on individual needs, including areas for improvement and specific skill development. To prepare adequately for the GMAT, one should devise a tailored study plan with a clear weekly schedule and objectives to ensure specificity and targeted progress. 

 

  1. Overlooking the significance of the mock exams 

Many students overlook the mock tests and only take them towards the end of their preparation. However, these tests are vital for assessing readiness, understanding exam patterns, and refining time management. The students should include mock tests throughout preparation.  Analysing performance after each test is crucial for identifying strengths and weaknesses.

  1. Selecting the wrong study material/classes 

Many students waste valuable time preparing with the wrong study materials and classes. Opt for high-quality study materials and classes tailored to your needs. Invest time thoroughly researching available options to make the optimal choice for your preparation.

 

  1. Neglecting time management on the GMAT 

 

Effective time management is crucial in the GMAT exam, as it prevents incomplete sections, reduces stress, and ensures accurate answers. Students should practice pacing themselves and answering questions within the allotted timeframe to build confidence for the exam.

 

  1. Not using the elimination process 

The standard error made by the test taker is when they are faced with multiple-choice questions, they do not utilise the process of elimination. One should start by eliminating the options they know are incorrect and not trying to find the correct answer directly. Hence, even when uncertain, excluding wrong choices enhances the likelihood of guessing correctly.

 

  1. Practicing without relying on the CAT format 

The GMAT exam is designed as a CAT (Computer Adaptive Test), meaning that the examinee determines the difficulty of the question. The more correct answers you provide, the more complex the questions get. Hence, one should take the mock test in the CAT format. Therefore, the students should practice in the format of the actual exam. 

 

  1. Not getting enough rest 

One should pay attention to emotional and physical health as one preps for the exam and goes into the exam, along with mental preparation. The week before the GMAT, one should be prepping more rigorously than in the previous months. One should not study at all the day before their exam to give their mind a complete rest. 

 

  1. Emphasizing only the strengths 

Numerous GMAT aspirants strive for a quant grade surpassing the 95th percentile, often neglecting their weaknesses. Instead, the goal should be to attain a balanced score across all categories, focusing on excelling in select areas. This approach enhances the overall strength of your application.

 

  1. Avoiding taking notes 

Sometimes, test takers need to take notes when they read a question or figure out the answer. While it may save time initially, omitting note-taking can prolong the process. Therefore, it's advisable to practice taking notes during practice tests and drills, ensuring familiarity by the time of the real exam.

 

  1. Experience test anxiety on the GMAT exam day 

Test anxiety can create issues, even for the most well-prepared test-takers. To avoid this situation, practice relaxation techniques like positive visualisation to manage stress and maintain focus. You should put in the effort and be well-prepared. Besides, it would help if you trusted your abilities and confidently approached the exam. 


  1. Being too much dependent on memorisation for GMAT concepts 

Memorising rules, concepts and formulas without understanding them will be problematic during the GMAT exam. Don’t depend on rote memorisation. Attempting to grasp the fundamental principles and implementing them in diverse situations can be beneficial in addressing issues with greater efficiency. However, this practice will also improve one’s capacity to adjust to different question formats. 

 

  1. There’s always a second opportunity 


The GMAT exam can be retaken at your convenience for $250 each time, with up to five attempts allowed annually. Don't panic if you receive a low score; analyse your strengths and weaknesses to improve performance and avoid repeating errors on subsequent attempts.
