How much subjects there are in a semester of intermediate icwai?

The Intermediate level of the ICWAI (now known as the CMA - Cost and Management Accountant) course doesn't have a fixed number of subjects *per semester*. The course is divided into groups of subjects, and you typically take several groups across multiple attempts/semesters, depending on your study plan and the examination schedule. There isn't a "semester" structure in the same way as a university degree. You register for specific groups of subjects and attempt them in the examination windows.
