The CAT question paper has four different segments, namely, Verbal Ability, Reading Comprehension, Problem Solving and Data Interpretation. These multiple choices questions and are required to be answered only with a HB pencil on a computer coded OMR answer sheet. For each incorrect answer you get negative marks. Every year, the IIMs change the question pattern to prevent predictability. You should therefore have a deeper understanding of concepts and their applications to succeed in the CAT. It is to be noted that you have to perform well in all the three sections of the CAT as the test evaluates the overall aptitude of the student.
