Engineering Ranking

Yes, you can appear for JEE Mains.

There is no engineering college which can offer job abroad. Legacy IITs and BITS - Pilani every year offer campus placement and offer placement abroad to few students.

Hello Subhrajyoti,
You can check the below mentioned links to see the list of top colleges in West Bengal:

BITS Pilani (Pilani campus) is the best engineering colleges for B.Tech CSE beside IITs & NITs based on its brand image, rankings, placement records, facilities and alumni network.

Hello Anupama,
In Mumbai, IIT - Powai has the best placements, whereas in Pune COEP has the best placements.
Good luck.

You need under 2000 rank to get into Computer Science. Mechanical and ECE are one of the best branches.

Petroleum engineering is a professional degree, where as hotel management is not. If you don't want to worry about studying then choose hotel management. Hotel management is mostly practical based. You can just enjoy doing it. In the present scenario where crude prices are low and many have lost their jobs because of this, its better stay out of it. One more thing, its really unethical to compare these two courses as they are like two different poles. First, be clear whether to do engineering or normal degree. You can also consider courses like marine, harbour, nautical science etc.

BE and B.Tech, both are same. You can choose as per your interest.

Depending on your field of interest, both courses are amazing with equally worth job opportunities. However, with my personal experience, I feel that hospitality sector is not only enticing, but also provides amazing job opportunities.
This sector is one of the fastest growing one and the academics are extremely interesting. My cousin and I pursued an Internship in the hospitality sector and grew overall as a person. She is currently pursuing BBA in hospitality, travel and tourism. You should give it a shot as well.
