Hi Sushabhan,
I think, you should go for certificate course in web designing, Certificate Course in Office Automation, Certificate Course in ASP. NET with C#, Certificate Course in Soft Skills Communicative English, Bridge Course in Mathematics. These are basic courses for beginner you can first go for them.
Good luck.

Some coaching institutes are:
IMS India
Cl Educate
Triumphant Institute of Management Education.

Hello! IIFT is a very college, not just in Kolkata but also in India, which does not accept CAT score; it accepts the score of the IIFT test. http://tedu.iift.ac.in/iift/finalplacements.php Kindly visit this link for details about its stellar placements. You can even consider IMI as a backup; it accepts XAT score.

Unfortunately, your graduation score is way below the eligibility criteria to pursue an MBA course. For placements, both the cities have one the finest B-Schools I. e. IIM Bangalore and IIM Calcutta.
