B.Tech Eligibility

Yes, Maths Students are eligible for any B.Tech course. Dairy Technology at first may seem like a course for Biology students, but it is also for Maths students. The course is aimed more on technology part than the dairy.

You are basically asking about IIT. IIT doesn't provide lateral admission and not even regular admission through management quota. Your Diploma is however eligible for admission into mining engineering. I would suggest pursuing the course from another college.

Firstly their is no fixed eligibility for placement during campus interview as it differs from company to company.The minimum requirement is you should pass with first class in all exams and your attendance should be at least 75% then you get selected by the college for campus selection. Hope this will help you.
Good Luck!
