My underestimation of this MBA

Just after 1.5 moths of classes we had our mid term and it just finishes last week. I think I underestimated this course, its actually started taking its toll on me. Its quite hectic and quite regularly hectic. Assignments, quizzes, projects and then mid term, do you think its too less for 1.5 months of classes. Also we did a whole lot of case studies specially in Management Accounting. I studied this much in one whole semester in my engineering :(

Now Midterms are over and again we have those cases, projects, assignments.......
