I am currently persuing b.tech in biotechnology from a private college. Im in the 3rd year now. Its neotia institute of technology in kolkata under wbut. 
I have a number of questions and im quite confused at the moment.
1) firstly after a btech doing ms or mtech which one is preferable?
2) what are the job opportunities after a mtech or ms?
3) which is the best place to do ms from?
4) what is the  minimum amount of fees you require to do ms?
5) what is the eligibility criteria for doina a ms or a mtech degree?
since i dont have a good percentage in my 12th standard is it going to affect the further studies ?
and lastly what is preferable after a btech in biotechnology ? a mba/ mtch/a ms degree?
6) how should i prepare for it?
as far is as interest is concerned im interested in the food sector or the marketing sector.
which will get me a better pay in future?
