2. It is important to understand that nailing the logical reasoning section requires you to have the right mindset. Critical thinking and analysis make it easier for you to solve puzzles and other logical questions.
3. Apart from practicing the questions from the previous years, one must solve brain teasers and SuDoKus in one’s free time.
4. Once you are at that stage of the preparation wherein you can identify the type of questions, you must initiate the process of allotting 8-10 minutes for each set. Time management plays a significant role in determining your success.
5. As you progress your preparation, it is only natural to develop a fondness for a certain type of question. However, you must never let that come in your way of attempting as many sets as possible.
6. Convert the given information into charts, diagrams, or tables, whenever necessary for better visual appeal. Visualization can be a true savior!
7. Don’t let the complexity of the language overwhelm you. Sometimes, the question is framed in a way that leaves you all baffled. But, if you pay attention, think clearly, and remain composed, you will realize that the problem is not as difficult as it seems.
8. Use the elimination technique wherever possible to save time. The question could be long and may contain unnecessary information.
Preparation tips for Data Interpretation:
1. Strengthening your understanding of certain things will cover many topics. For instance, ratios and fractions are used in pie charts, bar charts, caselets, line charts, etc.
2. Make your own tables wherever necessary. The comparison of the values in the tabular form can help you save a lot of time.
3. Use a calculator whenever required. However, you must learn multiplication tables up to 25 to make your life easier and solve questions as swiftly as possible.
4. They say there are no shortcuts to success but, there are shortcuts that can turn certain DI questions into a cakewalk. Learn those and master the art of identifying the correct shortcut required for a particular question.
5. Time does not believe in waiting for you to give the right answer, especially when you are a CAT aspirant. From the second month of your preparation, start challenging yourself to attempt the questions in a fixed time frame.
6. You don’t always need all the information provided in the question. After enough practice, a quick skim through the question paper will help you eliminate the unnecessary information right in the beginning.
Exam day tips for DILR:
1. Instead of starting the paper right away, spend the first couple of minutes analyzing the difficulty levels of all the questions.
2. The exam day is not the right occasion to test your expertise in mental calculations. So, use the on-screen calculator to save time.
3. Some questions will in fact be more difficult than others, and might even take more time than you initially intended to give it. One must have a thorough understanding of how to choose a question as selecting the right question is a battle half won. Learn to pick your battles because the CAT is all about striking a balance between speed and accuracy.
4. Considering the negative marking, imprint the word ‘accuracy’ in your mind and give your best to it.
5. Set a particular time limit for every type of question and don’t exceed the allotted time to maintain the required pace.
6. Start with the easier questions to gain the confidence you need while attempting one of the most important exams of your academic journey.
Becoming an expert in solving Data Interpretation and Logical Reasoning questions might seem too onerous. However, with an effective strategy and consistent efforts in the right direction, it will turn into one of your strengths before the exam. And once you achieve that, success will find your address sooner than you expect.
