Mechanical Engineering

For this you should search and see the placements of the college consistently and bonding with different companies.
Moreover, you should also, if possible, visit the college and ask the current studying students and take the feedback.

If you want to end up with your core subject as mechanical then prefer it first but as per the campus ranking IIT, Kharagpur is better than Guwahati but I'd suggest you to do mechanical from II, Guwahati.

Since, the future is going to be technical and digitized, I would suggest you to go for ECE but if you are really interested in doing mechanical, that is fine but doing ECE will give you a bright future.
Good luck.

You should attend a robotic camp or opt for an industrial visit and get some certification from them or you can take science olympiad exam.
Hope it helped.

If you are seeking in India then go for IITs and if abroad then there are lots of universities. You can also take BITSAT.

The question is a very relative one. The possibility of you getting admission depends on the cut off of the engineering college that you are applying to. As this varies from college to college, and also from year to year, one cannot directly answer your question.

All the best.

GRE and TOEFL/IELTS are the essential ones.

Hi Rajas,
Every university in US has a different entry requirements and different levels of selectivity. A top ranking university might also accept you if your overall profile is outstanding and you have an excellent GRE score. You must focus on preparing a good application package, check university websites for admission requirements and prepare accordingly. Check QS ranking for the university ranks and check universities below rank 30.
