Common Admission Test (CAT) 2020 is on November 29, 2020, which means the candidates only have 9 days left to polish their skills and prepare for the exam. DILR section in CAT is one of the most tricky sections. This is because it requires interpretation, logic, and quick thinking. The students must note that DILR is usually the decider section and the toughness level of the section has been gradually increasing over the years. However, the aspirants can crack this section with dedicated practice and a good time management strategy. To be able to cope with the last-minute revision of the Data Interpretation and Logical Reasoning section, here are some tips that are effective and easy to follow.
Focus on practicing as much as you can: The questions in DILR are based on data in tables, charts, graphs, diagrams, case studies, logical games, calendars, clocks, cubes, seating arrangements, blood relations, etc. Hence to be able to solve these questions on time and accurately, candidates have to practice as many questions as possible in the last few days. Mock test and previous year paper are the best resource to do so.
Practice time management: This year the candidates shall get 40 mins per section. Hence the candidates have to ensure that they are not spending a lot of time in one particular questions, but their time is equally divided among all the 3 sections. The best is to practice the DILR questions in a manner that all the questions are completed within 40 mins and with 100% accuracy.
Do not start any new topic in DILR now: Suppose a candidate has not yet practice the pie chart type question, then it is advised to just have a look at those type of questions. Do not start the topic from the scratch as this will only lead to confusion in concepts. Since CAT has negative marking, it is always better to focus on the strengths and get as many correct answers as possible.
Question selection: In the last week is for strategising, the candidates must figure out what type of questions they are most comfortable to solve. These questions must be solved first on the exam day. This will enable the candidates to stay high on confidence while solving the problems and will save time as well.
Accuracy is important: The candidates have to focus on getting a question accurate in one go. The level of practice must be such that the candidates can solve the question and get the correct answer in one go.
Practice to scan the questions: Most of the answers in the DILR section is hidden in the question itself. Hence, candidates need a sharp eye, out of box thinking, and ability to read between the lines. This can come from regular practice, try to understand the questions and read it more than once.
These tips are anecdotes for the candidates to cope with their last minute preparation of CAT 2020. There is no shortcut to success, these tips can just help the candidates to get a direction for last week preparation.
