I got selected for MBA batch. Is it true that single class strength is 70 students? How do they divide it into different sections?

Depends on whether you got selected in AICTE approved campus or not. As, most AICTE approved campuses follow a mandate of 60 per classroom.

Depends on which college you have taken admission in. Yes, there are colleges that run two sections with each of equal strength and also there are colleges which run only one section. The strength of students may vary as per college.

In the first year as everyone has the same subjects, there may be chances of only one or two classes. After you select your specialisations, students get separated as per their specialisations and classes are held accordingly.

Class strength would be around 350 to 400 and they would be divided into 2 sections.
