About CAT Exam:
Test Duration:
Test Pattern:
The test comprises of two sections:
(a) Quantitative Ability & Data Interpretation
(b) Verbal Ability & Logical Reasoning.
Once a section ends, aspirants can no longer go back to it. Aspirants will be presented with the section on Quantitative Ability & Data Interpretation first, followed by Verbal Ability & Logical Reasoning. Candidates will be given 15 minutes tutorial before the commencement of the main exam.
But the main difference lies in negative marking of the wrong answers. Negative marking in XAT is less than that of CAT.
XAT penalises by one fourth mark whereas CAT penalises by one third. For example - if one mark is awarded for every correct answer, 1/3 and 1/4 will be deducted by CAT and XAT for every wrong answer, respectively.
