How to prepare for Data Interpretation for CAT - The section most candidates consider to be the toughest in CAT is Data Interpretation and Logical Reasoning (DILR). This is mostly due to the presumed complexity and unpredictability of data interpretation for CAT. However, unlike the Quant Section or VARC, the gestation time to learn and ace DILR is far lower. Moreover, the chances of high accuracy in DILR also make it the most interesting section to prepare and crack. In this article, we talk about tips and tricks on how to prepare for data interpretation for the CAT exam.

Given that 40 minutes are allotted to complete the data interpretation in CAT 2024, where 5 sets of data have to be solved, the key to solving them is building familiarity and consistent practice. While the CAT exam consists of sets having data interpretation, pure logical Reasoning and a mix of both,. This article focuses on acing the data interpretation for the CAT exam.

Each of these topics expands on ways to dissect the presented data and analyze it. Simplifying data given into easily analyzable forms is the most important skill one needs to master to crack data interpretation and, of course, use the skill to succeed as a manager later on. Strong fundamentals in certain quantitative areas will aid you in your preparation for Data Interpretation.

To crack DI in CAT, proficiency in these quantitative topics is also required:

Preparation for Data Interpretation: The Winning Strategy

Your preparation for the DI strategy can be broken down into two phases. The first phase includes the general building of concepts and strengthening fundamentals. The second phase of preparation sees you gauging what works for you and what doesn’t. The goal is to discover a winning strategy that combines speed in answering and accuracy in solving.

How to prepare for Data Interpretation for CAT, Phase 1

A maximum of 2 sets of pure DI and at least one set of logic-based data interpretation questions are expected in CAT 2024, which means the paper will not cover all the above-given topics. But you cannot afford to miss out on questions on any particular topic. Therefore, it is necessary to cover the entire breadth of topics in your initial preparation for DI. Clear the fundamentals of each concept during this phase and solve basic problems.

You can also refer to and solve the DI questions from past CAT question papers. The more questions you see about a particular topic, the better your ability to understand the data. Aim to finish a chapter in two days of study and then move on to the next. During this phase, the time you take to solve a question can be ignored.

Parallelly, improving your calculation speed is essential. Data interpretation is a game of speed. The more time you save in DI, the more time you have to give to other sets. Although a calculator will be available during the exam, you can save precious seconds by doing the calculations yourself. Some tips in this direction are

  • Multiplication tables up to 20 are a must-know.

  • Knowing the decimal values from 1/2 to 1/20 can help save time on some percentage-related questions.

  • Adding numbers faster, finding whole number estimates of fractions help in solving that little bit quicker.

  • Techniques in Vedic math for multiplications can be handy.

If you find yourself bad at basic calculation, start your preparation for DI by spending at least 30 minutes a day doing calculations with random numbers. The speed and accuracy of calculations are incredibly crucial in the CAT exam. Repetition will help with improving and getting better at calculations.

DI Preparation for CAT, Phase 2

Once your fundamentals are in place, we begin to factor in the time taken to solve a question. Practice 3 to 4 sets (excluding the mock questions, if any) of DI questions every day with a timer. Each set should, ideally, take less than 8 to 10 minutes. Any longer, and you should bid goodbye to the set (during mocks). Fixating on a particular set can cost you the exam, which you will eventually discover during your mock writing sessions. But remember, worrying about the time isn't going to help you solve the question at hand. Instead, focus solely on the question and the time taken will automatically be shaved off.

Once your fundamentals are secure, start by giving topical tests and mocks. The crucial part isn't taking the test; it is the post-test analysis that helps you improve. See how long you spent on each of the DI sets and what you could have done differently that would have saved you time. Solve the DI sets again outside the test with a timer on.

Note: Do not brush off calculation mistakes as silly. Make a conscious effort to improve accuracy.

Ultimately, repetition is the name of the game, more so when it comes to preparation for data interpretation for the CAT exam. The more you become familiar with standard templates, the faster you synthesize the data. The more you solve, the quicker you calculate. And the more aware you are, the better your accuracy. Also, having a way with numbers will be mighty handy in acing the DI section in CAT. The aim is simple - save time here to use elsewhere.

An aura of unpredictability surrounds this section, creating an unnecessary fear/pressure that makes you put the paper on a pedestal. You need to realize that all other candidates must face the same paper, and the one who maintains equanimity will come out on top.

Other Tips for DI Preparation:

  • Try not to get intimidated by seeing voluminous data sets. Very often, these are the easiest, and the data is there to throw you off the track.

  • Practice questions on increasing/decreasing percentages and comparing ratios.

  • When solving a set in DI, do not solve the dataset entirely before moving to questions. Read the question first and do the bare minimum to be able to answer that question. Tabulate the values you have obtained during the calculation as they might help solve questions that come later.

  • Learn to use options to get to the answer. If comparing numbers, do not drill down to decimal places. Instead, bring them to comparable forms (fractions mostly).

  • Using the on-screen calculator can be helpful for lengthier calculations. Hence a few hours can be devoted to getting comfortable with the calculator. However, accurate mental calculations would be ideal for saving time.

Hello Aspirant,

Yes, you can sit for the CAT exam with a CGPA of 8.5. However when you do crack the CAT exam and have to sit for the interview round or the Group discussion round, you will be asked the question about 4 years of graduation, in which case, carry your hospital records and medical certificates to prove to them that you actually had some health issues during your graduation. This shouldn't be a problem because you had a genuine reason for the one-year gap.

Hello,

Getting admission to an IIM without taking the CAT is possible through alternative routes such as:

1. Executive MBA (PGPX,EPGP,ect .)  : Many IIMs offer Executive MBA programs for experienced professionals, which may require GMAT scores instead of CAT .

2.Integrated programs: Some IIMs offer integrated programs like IPM (Integrated Program in Management), where admission cab be based on entrance exams other than CAT.

3.Doctoral programs (Ph.D.): Some IIMs accept GMAT/GRE scores for their doctoral programs .

4. Specialized Courses: IIMs offer various short-term and ccertificate programs that don't require CAT scores.

Check the specific IIM websites for detailed admission criteria and processes for these programs .
