Hello Hemkumar,
Your cut-off is really good. But it is difficult to get Mechanical or EEE at the main campus of Anna University if you belong to OC, BC etc. You can get it if you belong to SC or ST only. Hence you may try your best at th counseling to get the main campuses, or atleast the top colleges like PSG, SSN etc.

Hi,

Hello Sagar, It's quite interesting to know that you are interested in doing your graduation in only one year via some fast track means. But I am afraid, in India minimum duration of any graduation course is three years. Best wishes.
