CA/CMA Exams

In India, two professional certifications are significant for commerce graduates who want to work in accounting, finance, or other similar fields. These certificates are the Chartered Accountant (CA), given by the Institute of Chartered Accountants of India (ICAI), and the Cost and Management Accountant (CMA), awarded by The Institute of Cost Accountants of India (ICMAI). They both have a high reputation because they’re difficult to achieve, but they hold significant value when finding jobs. Although these certifications can lead to successful careers, each one focuses on slightly different skills:

Why is the CA exam considered one of the toughest exams in the world?

Refer to the reasons below to understand why CA is among the toughest exams in the world.

  • After passing the CA Foundation exams, most students begin to study or enroll in coaching classes. The first attempt is scheduled for within 9 months following these exams.
  • During those 9 months, the student must understand ideas from 8 separate extensive subjects that demand high memory capacity.
  • For CA Final 2023, the pass percentage for Group 1 was at 9.46%, followed by Group 2 with a rate of 21.6%. The joint pass percentage for both groups remained at around 9.42%.
  • Candidates might encounter a significant problem: the potential of failing to succeed in certain test levels at their initial try.
  • In these scenarios, candidates take reattempts until they succeed. This can lengthen their total time to become a CA.
