Kolkata

Hi, If you are targeting top 20-30, then you must write CAT. Alternatively, you may focus on IIFT SNAP (for Symbiosis), NMAT. NMAT- NMIMS
MHT- CET- for MBA colleges in Maharashtra
SNAP- Symbiosis college
XAT- for XLRI
IIFT - for IIFT D AND IIFT Kolkata
CMAT- Many colleges accept CMAT Score.

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.

IEM takes admission through WBJEE and JEE Mains and not through any other joint entrance examination. Your rank should be between 700 to 800 (GMR) to get into IEM. IEM offers 12 seats for mechanical students through JELET. Usually, if seats get vacated at the end of the first year and there will be a chance of admission through JELET. In Techno India Salt Lake City for lateral entries eligibility criteria is that a candidate should have minimum 60% aggregate in Diploma in engineering.
Hope this helps.
