Hi Soumyadeep,
Tell your friend to be relax. If you have potential, no one can stop you. He will definitely get job that too in multinational company if he is good enough to crack the interview. So, percentage doesn't matters you knowledge do.
Best of luck!

Here is a list of good colleges in India offering Mining:
https://www.shiksha.com/b-tech/colleges/b-tech-in-mining-engineering-colleges-india.

Passing marks are usually around 35% of total. And total marks differ for each college and course. So, there is no straight answer for it. But you should aim for atleast 50%.

There are only some certification and diploma that can be done in a duration of 2 years.

This is just an example the duration of course ranges with college. Look for colleges near you.

Both are good. If you want to work in a Technical field then do B.Tech or if you can work in any company then do BBA as it will be only 3 years conpared to 4 years B.Tech. But again when you study in B.Tech your knowledge will increase and you will have better chances of getting a good score in CAT.

Hi, it depends about your aptitude. B.Tech is an undergraduate academic degree conferred after completion of a three-year, a four-year, or even a five-year (such as in Nigeria) programme of studies at an accredited university or accredited university-level institution. Merchant navy officers are employed by commercial shipping companies to work on all kinds of seagoing vessels, such as cruise liners, cargo ships, tankers and hovercraft. These guys typically adopt a deck officer or engineering officer role in a team leading capacity.
