Engineer

Hello Ritika,
To get into a good and reputed college for MBA, you need to work both hard and smart. You can give various entrance exams like CAT, XAT, IIFT, etc. as per your convenience and your dream college. Also, if you clear all the necessary cutoffs, then you also need to prepare for the subsequent interview rounds held by the colleges (in which you get shortlisted).

I would suggest you to go for UEM, Kolkata for its good consistent placement record and have good infrastructure too. You have the desired qualification to pursue your desired streams.

Automobile Engineering is a branch of engineering that deals with designing, manufacturing and operating automobiles. It incorporate elements of mechanical, electrical, software and safety engineering as applied to design and manufacture buses, bikes, trucks and other vehicles and machines.
A robot is an automatic mechanical device guided by a computer program or electronic circuitry which enables it to perform tasks assigned to it. It is a system that contains sensors, control systems, manipulators, power supplies and software, all of which work together.

We can't predict whether all the state level entrance exams are going to be one (JEE) or not.
But in 2017, many prestigious institutes in India changed their intake system from state-level exams to JEE.
For example, HBTI used to offer admissions through UPTU but from 2017 admission will be based on JEE Mains. S, it is not going to happen in 2018, but in upcoming years there will be only one exam, JEE.

Hello Goutam,

However, as per your rank, your chances are slim for these colleges.

Taking a year drop to score more in JEE Mains is quite risky. If you have a good JEE score, you just take part in the counselling because tomorrow cannot be predicted prior, anything may happen (don't misunderstand). Please understand what I mean.
All the best.

If you want to good job then improve your communication skills first and as per your profile, operations or production management is the best suitable for you.
