The concept is probably the easiest to understand as it deals with the basis of counting but is found to be confusing for many aspirants. In this course you will learn basics of base system as well able to solve advance questions asked in different MBA entrance examinations.For CAT 2018, not many direct questions will be asked related to Base Systems, but they will used in a lot of questions, directly and indirectly.

Base System for CAT Examination

One of the key ways of cracking CAT examinations is by developing a thorough understanding of the existing Examination Pattern. Referring to previous year question papers help students do this by providing them the necessary information about syllabus and topics covered in the exam.
