Exam

Hello,
IIAE exam. The information available says that students have to apply based on their performance in class 12th and it does not talk of any exam by IIAE. I am attaching a link that will give you all the required information about different aspects of the admission procedure in this institution.

Best wishes to you.

Hello,
According to the Council of Scientific & Industrial Research, 16th June 2019 is the date for CSIR NET June 2019 as of now. The application process for it was closed on 22 March 2019. As per the council the admit cards will be available from 1st week of June 2019. In case you could not fill the form for June Exam or cannot give the exam for some reason, you can appear in Dec 2019 session of CSIR NET exam. Few days back I came across a very nice blog which consisted all the notifications related to CSIR NET exam.

Yes, you are eligible for the same course. You can get admission. Good luck.

You have to give the entrance exam, then only you will be getting a chance for getting admission in it.

Yes, you should do MBA after Bachelors of Engineering in civil, because it will not only give you an extra scope, but also give you a plan b what if you cannot get a good job in civil engineering, so at least you have a MBA degree with you which can not only give you a good job, but also great package.

I am afraid, one needs to have scored minimum 50% marks at graduation level to get admission into MBA. Since you have only 47% you don't qualify the minimum criteria for admission into MBA irrespective of the score you achieve in CAT.

Hello,
Yes, there are chances of you getting this college.
All the best.

Both the ranks are excellent. You should follow your passion
Good luck.
