Hi

Yes, you can definitely pursue an MBA.

The minimum eligibility criterion for admission is at least a 3-year bachelor's degree with at least 50 percent marks or equivalent (45 percent for SC/ST or persons with disability (PWD) category, of any of the Universities or possess an equivalent qualification recognised by the Ministry of HRD, Government of India. 

Your graduation marks will be considered while shortlisting for GD-PI process. Yout 10th marks, 12th marks and graduation marks will be considered at this step. The weightage given to them differ from college to college.

for MBA, you don't need to have any specific marks for the admission all

you need is to be a  graduate or even a final year student can appear for the exam. There are many management entrance exams like CAT MAT ATMA GMAT and many more. Just have a good mark in the mentioned entrance tests your admission will be confirmed after the GD and PI.

during placement session, they do ask for the past academic profile. mostly in the financial and the consultancy sectors. But in the case of the marketing and sales they do never ask for your past academic records.hence in the marketing HR operations the graduation marks doesn't play the role but the converse is true in the financial sector.

all the best!!!!!
