After reviewing 100 NMAT attempts, MBA Karo mentors identified several common mistakes that candidates make while solving Quantitative Ability questions.
The main issue is not the lack of mathematical skills but the ability to manage an adaptive exam under sectional time constraints.
The following mistakes stood out across the 100 NMAT attempts:
- Sloppy execution in the first 8-10 questions
- Getting trapped by early questions
- Leaving unanswered questions at the section timer’s end
- Not allocating different levels of effort to DI questions
- Failing to use calculation shortcuts
Each of these mistakes can impact the final score since NMAT does not allow answer revisions and does not penalise for incorrect responses.
Read ahead to know what our mentors suggest to address these issues.

5 Most Common NMAT Quant Mistakes: What 100 Attempts Revealed
Here are the 5 most common NMAT Quant mistakes shared below for reference:
| Rank | Common Mistake | What We Observed | Better Approach |
| 1 | Sloppy execution in the first 8-10 questions | Candidates rush early questions and make avoidable calculation errors | Spend an additional 10-15 seconds on each of the first 8 questions |
| 2 | Getting trapped by early questions | Candidates spend too long trying to crack unclear questions | If the question is not clear within 30 seconds, make an educated guess and move ahead |
| 3 | Leaving questions unanswered | Candidates assume unanswered questions do not matter because there is no negative marking | With 2 minutes left and 10 questions remaining, immediately mark educated guesses |
| 4 | Treating every DI question equally | Candidates spend equal time on every question in a set | Use estimation or educated guessing on calculation-heavy questions and move to easier ones |
| 5 | Ignoring shortcut rules | Candidates use long calculations for questions that can be solved much faster | Use unit digit, approximation and option-based techniques |
Sloppy execution in the first 8-10 questions
One of the common mistakes that stood out in our mentors’ analysis of 100 NMAT attempts was the tendency to rush the first 8-10 questions.
The candidates try to save time by spending less than a minute on each question. However, this approach backfires in an adaptive exam as the system assesses the initial performance to estimate the candidate’s level and adjust the following questions’ difficulty.
What should test takers do differently? According to our mentors, the first 8 questions should not be rushed, as it would ensure 100% accuracy.
Candidates should spend an additional 10-15 seconds than they would normally on average questions. It does not mean that they should try to spend 30-40 seconds on an easy question. Instead, they should slow down enough to ensure that they
- Read the question correctly
- Understand what is being asked
- Do simple calculations
- Double-check before selecting an option
The point is to avoid avoidable mistakes in the first few questions. They should be treated as accuracy challenges rather than speed challenges.
Our Mentor Takeaway: Do not try to beat the clock at the beginning of the test. Save a few seconds per question to avoid calculation errors and ensure that the selected option matches the question.
Getting trapped by early questions
The next common mistake was spending too much time on a single question. The candidates tried to understand complex statements and lengthy calculations for questions that appeared early in the test.
According to the mentors’ analysis of 100 NMAT attempts, such questions tended to drain more time than average.
What should test takers do differently? The candidates should follow the 30-Second Rule – if the approach is unclear within the first 30 seconds, it is wise to make an educated guess and move on to the next question.
The point is not to guess blindly but to use the process of elimination to identify the most likely correct answer. It will help to minimize the impact of a difficult question.
For example, if the question is unclear at first glance, candidates should
- Spend the first 30 seconds trying to understand what is being asked
- Use the process of elimination to select the most probable answer
- Move on to the next question without trying to calculate the exact answer
Why is it important to follow the 30-Second Rule? It becomes impossible to predict the difficulty of subsequent questions in an adaptive exam.
Therefore, it is unwise to invest too much time in a single question. Instead, the test takers should focus on maintaining an average time per question.
Our Mentor Takeaway: Do not waste time on confusing questions. If the approach is unclear within the first 30 seconds, it is wise to make an educated guess and move on.
Leaving unanswered questions at the section timer’s end
According to the mentors’ analysis of 100 NMAT attempts, the candidates often left the last questions unanswered when the timer ran out.
The test takers knew that NMAT does not penalise for incorrect responses, but they failed to make educated guesses when needed.
What should test takers do differently? They should follow the 2-Minute Emergency Rule – if there are two minutes left and ten questions to go, it is time to switch to rapid-fire mode and guess the answers to the remaining questions. The rationale is simple: an answered guess is better than an unanswered question.
Why is it important to follow the 2-Minute Emergency Rule? The candidates should always try to maximise the number of answered questions within the allocated time.
They should keep track of the remaining time and the number of questions to identify how much time they can spend on each. If the time runs out before all questions are attempted, the test takers should prioritise speed over accuracy.
Our Mentor Takeaway: Do not leave blank answers at the end of the section. Always try to answer the remaining questions with educated guesses when the time runs out.
Treating every DI question in a set equally
When it comes to Data Interpretation, the candidates tend to solve all questions in a set at the same pace. According to the mentors’ analysis of 100 NMAT attempts, it is a mistake as one of the questions often requires more calculations than others.
What should test takers do differently? The candidates should try to separate easy and calculation-intensive questions within a set. It is wiser to spend more time on the former and less on the latter.
For example, if a DI set contains four questions and one of them requires extensive calculations, the test taker should
- Solve the remaining three questions first
- Spend more time on the calculation-intensive question to ensure that the answer is correct
- Avoid rushing as the calculations are already time-consuming
The point is to maximise the number of correctly answered questions within the allocated time.
Our Mentor Takeaway: Do not solve all questions in a DI set at the same pace. Allocate more time to calculation-intensive questions and less to others.
Ignoring shortcut rules
The mentors noticed that some candidates knew various shortcut rules but failed to use them during the exam.
According to the analysis of 100 NMAT attempts, Many candidates spend nearly 3 minutes on calculations that can be solved in 30–40 seconds by using the answer choices smartly.
What should test takers do differently? They should use various shortcut calculation rules whenever applicable. It will help to minimize the time spent on each question and increase the chances of scoring higher.
Some of the calculation rules that MBA Karo mentors recommend are as follows:
- Unit Digit: It is often possible to identify the correct answer based on its unit digit
- Approximation: If the answer options are far apart, it is possible to use approximation
- Option-Based Solving: In some cases, it is possible to use the process of elimination to identify the correct answer
The key is to use the aforementioned rules whenever applicable. The test takers should always try to find the fastest way to reach the correct answer.
Our Mentor Takeaway: Do not waste time on calculations when a few seconds would have sufficed. Use various calculation shortcut rules to minimise the time spent on each question.
What Our 100-Attempt Analysis Says About NMAT Quant
The mentors’ analysis of 100 NMAT attempts has demonstrated that the candidates often fail to manage time efficiently while attempting Quantitative Ability questions.
In most cases, the issue was not a lack of mathematical skills but the inability to make optimal decisions under adaptive sectional time constraints. The common mistakes included
- Rushing the first few questions
- Spending too much time on a single question
- Leaving questions blank when the timer ran out
- Allocating equal effort to all DI questions
- Failing to use shortcut calculation rules
The expert analysis also showed that these mistakes significantly reduced the final scores as the candidates failed to maximise the number of correct answers.
NMAT Quant Strategy Based on Our Mentors’ Analysis
Having identified the common mistakes, it is possible to develop an optimal strategy for the NMAT Quantitative Ability section.
It will help to avoid rushing the first few questions, spending too much time on a single question, leaving questions blank at the end of the section, allocating equal effort to all DI questions, and failing to use calculation shortcut rules.
The following five rules will help to address the five most common mistakes:
Rule 1: Do not rush the first few questions
The candidates should spend an additional 10-15 seconds on the first 8 questions to ensure that they read the question correctly and do not make calculation errors.
It is better to sacrifice speed for accuracy in the beginning and maintain a steady pace throughout the test.
Rule 2: Do not get trapped by early questions
If the approach to a question is unclear within the first 30 seconds, the test taker should make an educated guess and move on to the next question.
It will help to avoid spending too much time on a single question.
Rule 3: Do not leave questions blank at the end of the section
If there are two minutes left and ten questions to go, the test taker should switch to rapid-fire mode and answer the remaining questions with educated guesses.
It is important to maximise the number of answered questions within the allocated time.
Rule 4: Do not allocate equal effort to all DI questions
The candidates should try to separate easy and calculation-intensive questions within a set.
It is wiser to spend more time on the former and less on the latter.
Rule 5: Use calculation shortcut rules
The test takers should always try to find the fastest way to reach the correct answer. It is possible to use various calculation shortcut rules, such as the unit digit, approximation, and option-based solving, to minimise the time spent on calculations.
Conclusion
The mentors’ analysis of 100 NMAT attempts has demonstrated that the candidates often fail to manage time efficiently while attempting the Quantitative Ability section.
They rush the first few questions, spend too much time on a single question, leave questions blank at the end of the section, allocate equal effort to all DI questions, and fail to use calculation shortcut rules.
However, it is possible to avoid these mistakes with the right approach. Instead of trying to solve more questions, the test takers should focus on making optimal decisions while attempting the NMAT Quantitative Ability section.
