How to Prepare for DI and LR for CAT 2021?
The preparation for Data Interpretation requires a lot of practice. The syllabus of DI is much more defined than the syllabus of the other sections of CAT, hence a different strategy is required for its preparation. CAT Data Interpretation syllabus covers almost all the types of questions of data analysis and data comparison that could be formed on bar diagrams, data tables, graphs, pie charts among other modules for the representation of data. With regular practice and improvement in the skills of Data Comparison and Data Analyst, the DI questions of CAT can be answered easily and in a much shorter time.
Logical Reasoning questions in CAT are generally based on a guide to arrive at good and proper decisions by following a systematic thought process. The LR questions are based on natural human instincts that are designed to lead the candidate and help him/ her arrive at the right answer option by following the prescribed flow chart of Logical Reasoning. The objective is not to only get the correct answers of Logical Reasoning but to get the correct answer in optimum time and with acceptable accuracy. Candidates need to be quick in mathematical calculations while maintaining accuracy in order to perform well in the LR section.
Primarily, all the sets of DI questions can be further classified into the following categories.
1. Calculation Based: These are the sets that have questions that deal with the increase or decrease in percentage or in the nominal increase/ decrease. These questions require good control of the candidate over basic calculation and approximation.
2. Counting Based: These are mostly large data sets in which the candidates are supposed to count the instances which meet the needs of the questions. The questions under these sets require focus and patience so that the test taker can ensure that he/she does not commit a single mistake.
3. Logic-Based: In the CAT exam, sometimes charts are used to give data in ranges or with conditions where it is not possible to find the exact data. In such cases, the candidate is usually asked to find a number that can be arrived at by fulfilling the need to maximize or minimize the number. The candidate needs to use strong logic to deduce an answer to these questions.
4. Structure-Based: These comprise some special sets. They are time-consuming questions and the chances of them being asked in CAT 2021 are less. They include questions like sales-disposal data of a specific product in the market, goals of various teams in a tournament, etc.
