For most Indian MBA aspirants, achieving an exceptional score in the CAT exam is the primary goal. A strong CAT percentile opens doors to IIM Ahmedabad (IIMA), IIM Bangalore (IIMB), IIM Calcutta (IIMC), IIM Lucknow (IIML), IIM Indore (IIMI), IIM Kozhikode (IIMK) FMS Delhi, MDI Gurgaon, and many more tier-1 colleges.
At the same time, an increasing number of candidates are starting to consider the GMAT exam as a backup option to CAT, especially for the programs offered by ISB, SPJIMR, BITSoM and IIMK. Amongst those aiming at executive MBAs, the percentage is even higher.
This raises an important question:
When should I give the GMAT exam?
Like most things, the answer is subjective to every candidate’s individual circumstances. In this article, we'll discuss the ideal GMAT timeline for CAT aspirants, explore the mistakes candidates commonly make, and help you decide the stage at which adding the GMAT to your repertoire leads to the highest strategic advantage.
Certainty: GMAT's Advantage
Most candidates spend a lot of time thinking and worrying about test scores. Will I get the score that I want? Will I get into my dream school this year?
Now imagine, if someone told you “No matter how CAT goes, here’s a score that still allows you opportunities as a backup”. Doesn’t that sound like a boon?
Knowing that you already have a competitive test score in hand changes the way you approach the rest of the application process. It becomes easier to shortlist schools, plan applications, prepare essays, and make career decisions.
More importantly, certainty reduces mental workload.
Candidates who are constantly worrying about future test scores often struggle to focus on the task immediately in front of them. On the other hand, candidates who have already secured a strong score can direct their energy toward interviews, applications, profile-building activities, and even their current jobs.
This creates a positive feedback loop:
Higher certainty → Better focus → Better performance → Better results → Even higher certainty
One of the biggest advantages of taking the GMAT at the right time is not just the score itself. It is the flexibility and confidence that comes from having additional options available. If you have a good GMAT score in your back pocket, you’re less worried about CAT, so you also perform better in CAT. Students often report performing much better when they’re less stressed about the outcomes of a test. They teach us about diversified portfolios in finance, why not employ the ideology here?
CAT 2026 and GMAT Planning
Candidates prepare their CAT strategy well in advance of the exam. Now that there is another exam, it is ever more important that they have their strategy ready months before CAT.
CAT is conducted on the last Sunday of every November and is hence expected to be held on the 29th of November this year,
One advantage of the GMAT exam is that it is much more flexible. It can be taken at any time, with a vast set of available test centres and multiple times within the same year. This means that candidates have the choice to decide when they want to sit for the exam. As a result, candidates utilise the months leading up to CAT to explore the GMAT pathway, possible admission routes and potential courses that can act as their backups. What this also means is that you can wait to sit for the GMAT until you are achieving GMAT Mock scores that are close to your desired scores.
The Biggest Mistake: Preparing for CAT and GMAT Simultaneously
The most common misconception that candidates have is “Since CAT syllabus and GMAT syllabus have overlapping regions in Quantitative Ability and Reading Comprehension, I should prepare for them simultaneously”.
In reality, a high overlap in syllabus does not necessarily translate into a high overlap in ideal approach. Syllabus is not the only thing that determines the similarities between two exams. GMAT exam pattern is vastly different from CAT exam pattern. The exams fundamentally test different skills and hence award different approaches.
We’ll skip the details in this article, but you can learn more about the differences in exam patterns here.
For most candidates, trying to optimize for both exams simultaneously results in lower performance in both.
Now let’s look at the different approaches you should take, depending on what your specific circumstances are.
Scenario : First attempt at CAT
If this is your first CAT attempt, the recommendation is straightforward: Focus entirely on CAT.
Most first-attempt candidates significantly underestimate the preparation required to maximize their CAT percentile. Dividing attention between CAT and GMAT preparation usually creates more problems than it solves.
Instead, focus on:
- CAT mock tests
- CAT Sectional tests
- Time management
- Accuracy under pressure
- Percentile maximization
Once the CAT is over, you can evaluate whether a GMAT attempt makes sense based on your results and admissions goals.
Recommended Timeline
Period | Focus |
June-November | CAT Preparation |
November | CAT Exam |
December-January | Evaluate GMAT Options |
February-March | Attempt GMAT |
Scenario 2: Second attempt at CAT
This is where the GMAT becomes significantly more relevant.
Many candidates spend an entire year preparing for a second CAT attempt without considering alternative pathways to top MBA programs.
A smarter approach is often to secure a GMAT score before beginning another CAT cycle.
This approach offers several advantages:
- You secure a valid GMAT score
- You create optionality for ISB and other GMAT-accepting programs
- You avoid placing all your admissions hopes on a single exam
- You enter the CAT season with significantly more certainty
By the time CAT arrives, you already have a backup plan in place. If you get a good GMAT score, you walk into CAT with an application at ISB that is far ahead of any other application you’ll make.
In this case, when you start your preparation is dependent on how early you decide that you want to attempt again. The timeline below is an estimate with the assumption that you were nearing the end of the interview cycle when you made the decision. If you have decided earlier, simply move the timeline accordingly.
Recommended Timeline
Period | Focus |
February-April | GMAT Preparation |
May/June | GMAT Attempt |
June/July-November | CAT Preparation |
Scenario 3: Third attempt at CAT
This is the candidate that GMAT aids the most. If this is you, you should seriously consider the GMAT exam.
Unlike a first-attempt candidate, you have years of aptitude preparation behind you. You likely have strong quantitative fundamentals, your Reading Comprehension has improved significantly. You are familiar with standardised testing in a way that most people aren’t. Nothing replaces experience, which makes you irreplaceable.
Hence, it is no surprise that most third-attempt candidates find that preparing for the GMAT requires significantly less effort as compared to preparing for CAT. So, it makes even more sense to sit for the exam before CAT is conducted.
A strong GMAT score can immediately open doors to programs such as ISB and other leading GMAT-accepting MBA programs. If you’re able to achieve one early enough, you might have your ISB application in before you even apply for CAT.
Moreover, it gives you certainty before entering another year of CAT preparation. Walking into a third attempt is no easy feat in terms of psychological pressure and mental fatigue. The simple fact of the existence of a strong application in one of the top schools relieves some of that pressure. Even if CAT remains your primary goal, having a strong GMAT score in hand ensures that you are not placing all of your admissions opportunities into a single examination window.
How Much CAT Preparation Transfers to the GMAT?
One of the biggest advantages CAT aspirants have is that they are not starting from scratch. Many of the skills developed during CAT preparation transfer effectively to the GMAT, including:
- Arithmetic
- Algebra
- Combinatorics
- Sectional Time Format
- Reading Comprehension
However, candidates should be aware that the GMAT introduces additional challenges, particularly in:
- Data Insights
- Adaptive testing
- Question selection strategy
- Accuracy management
In CAT, the exam strategy is directly driven by a maximum-score approach. In GMAT, it is about time-score tradeoff. Getting a question wrong on CAT is brutal. Getting a question wrong on GMAT is expected. The best way to understand your current skill overlap is to take a GMAT Diagnostic Test.
CAT vs GMAT: Which Should Be Your Priority?
For most Indian applicants, the answer remains simple:
CAT should be Plan A. GMAT should be Plan B.
The goal is not to prepare for both exams simultaneously.
The goal is to create multiple pathways to a top MBA program.
A strong CAT score creates multiple opportunities, but with a single point of failure.
A strong GMAT score creates limited but strong opportunities with no single point of failure.
Candidates who plan their timelines effectively can often keep both options available without dramatically increasing their preparation burden.
Conclusion
The GMAT should not be viewed as a replacement for the CAT. It should instead be viewed as a contemporary exam that allows you to maximise your MBA opportunities.
If this is your first CAT attempt, stay focused on the CAT.
If you are considering a second or third CAT attempt, securing a GMAT score can provide valuable flexibility, reduce uncertainty, and ensure that you are not relying entirely on a single admissions cycle.
Most candidates maximise their MBA opportunities after the exam. In reality, the process can be started much, much earlier.
