Mechanical Engineering

Hello Sughand,
There is a little chance to get BIT Mesra as BIT is GFTIs. So, counseling is done by Josaa. So, please see the closing rank by josaa for GFTIs:

All the best.

Both branches are equally good and very good job opportunities. CSE has an edge over Mechanical Engineering in term of job opportunities based on last few years data and job market forecast.

Hello,
KIT, RWTH Aachen, TU Darmstadt, TU Mnchen, TU Braunschweig and Clausthal University of Technology are some of the most reputed universities for your field in a particular order. There are no good and bad universities in Germany and every German Technical University has a strong presence in terms of research and teaching.

Aerospace engineering is a niche branch of engineering with limited career opportunities in comparison to Mechanical Engineering because Mechanical engineers are employed in all type of sectors and industries.

You can not specialize in Computer Science and IT field while undergoing BTech Mechanical Engineering degree. You will be able to do only compulsory computer language courses and CAD-CAM courses. If your Engineering college has flixibility to alliw or choose interdisciplinary electives then you may choose few courses such as Data Structures, RDBMS etc from CSE department. You are advised to do computer software courses during your summer vacations.
