SECTION-B
The depth of subject matter in this section shall be similar to GRE.
1. Critical Reasoning [5 ××× 3]
Critical reasoning sections aim to test the candidate's comprehension of the interpretative abilities in English as a language of business and communication. Critical reasoning questios measure your ability to read with understanding, insight and discrimination. These questions explore your ability to analyze a written passage from several perpectives, including your ability to recognize explicitly stated elements as well as underlying statements or arguments and their implications. This section measures reading comprehension and critical reasoning skills in a multiple-choice format.
The Critical reasoning section measures your ability to:
• analyze and evaluate written material and synthesize information obtained from it.
2. Mathematics [45 ××× 1]
The format of these multiple-choice questions varies. The solution may require simple computations, manipulations or multi-step problem-solving. These sections aim to test the candidate's understanding of
