Mechanical Engineering

This depends upon the Diploma but the value of a degree and Diploma is different.

Hello Rushikesh,
If you want to make your career in B.Tech (mechanical engineering) then you should choose Science PCM stream in your 11th and 12th class. PCM means physics, chemistry and mathematics. Study carefully and with attentive attitude.

Dear Ramanath Mishra,
As per my knowledge, you can not get admission anywhere by showing the degree from EIMSR because as per the data available on the internet this particular institute is completely fake there are many people complaining about this institute, though I do not have any valid information about this EIMSR. So I would recommend you to cross-verify your BE (Mechanical Degree).

Yes sure. All you need to do is cracking and ranking very good in GATE(cse). But I will suggest that it will be better if you can continue with mechanical engineering in M. E. because your plan of suddenly switching your stream from core to noncore might backfire .

I don't think any college would offer such change in stream. But even if it does, (you might get IT but not CSE) you should be well prepared about the pre requisite. Learn C for starting because they already know C language as it was in their first year course. Moreover, their subjects might seem difficult to you as you've read mechanical engineering before.

Yes you are eligible. Candidates who passed 12th with PCM from any recognised board are eligible for engineering entrance exams like JEE Main KEAM VITEEE MAHE etc.

Hello Gajendra, as you have mentioned in the question, you already took admission into Amity University which is a good choice and I also hope you have done ample research before opting for this course. I would appreciate you have choose to do mechanical engineering in order to be a mechanical engineer.

You can refer these courses:
Biomechanical Engineering
Master in Advanced Mechatronics
Master in Industrial Mechanical Engineering (M.Sc)
Master in Aeronautical Engineering
Master in Textile Engineering, Clothing, and Textile Engineering
Master of Engineering (Mechanical)
Master in Mechatronics and Robotics

Yes, you are eligible to get admission in IIMB for executive PGDM.
