B.Tech

I think yes, you can get into various engineering colleges under AKTU. There some colleges which are not able to fill all seats and so I think you have very good chances of getting CS but not in a good ranked college.

There is nothing better than CIPET for tool and die making.

This fee includes mess fee, tuition fee, hostel accommodation, etc. It is about 20 Lakhs for IIM B, IIM A has raised it this year says the news and IIM C is slightly lower than 20 Lakhs. IIMs have the same fee .for you.irrespective of how well you scored in cat .for the old IIMS it is around 18-20 lakhs.
So CAT is something which gives you eligibility for the final admission.
So basically comes down to money, if you can afford i would say you don't have to worry about CAT. But getting a good score will definitely improve your chances of getting a seat and some reimbursement.

No, you are not eligible to do Diploma course in airline management because you have some backlogs. First of all clear your backlogs and then you will be able to do airline management.

Yes, you will have your seat if do not get any better option.

If you have done in electrical engineering then go with the same. It will be beneficial for you.

Since you are a student of fourth year BE you can definitely attend the GATE this year.
