Distribution of Questions across various areas for Paper-II

Maths

NOTE: The terms “Easy (E)”, “Medium: (M)”, and “Difficult: (D)” are based on the following points:

Easy (E):

Questions which involve direct substitution in the formulae.

 
Medium (M):

Questions which essentially involve application-level; which requires a minimum of 2-formulae; and in some cases - questions which essentially call for lengthy solution, thereby, requires more time to be spent (by the student) – to arrive at the answer.

 
Difficult (D):

Questions which are all indeed difficult to be solved purely in terms of it’s complexity, Questions which involve “application of several concepts” the knowledge of which is a prerequisite for a student to arrive at the correct answer. Questions under this category put a student’s “analytical aptitude” to test.
