greetings rohit,

mba is a professional course and thus requires a considerable amount of effort to excel.

moreover it depends on the specialiostaion for example finance is tougher than HR and so on.

a typical MBA program consist of 2 years of study divided into 4 semesters.

you may have to study subjects like financial accounting, mangement accounting, marketing management, organisational behaviour, statistics, operational research, business economics, financial models, derivatives, corporat finance, investment banking, human resource development, digital marketing, portfolio management, managerial economics, decision sciences, data analytics, business communication, business laws etc

if you are from a commerce backgroud, it will be easier for you.

hope it helps.

good luck.
