Indian Institute of Technology, IIT Bombay

All are important in their respective field.
But, by seeing the growth I can say that the CS and IT industry are growing much faster.
Choose that field in which you have interest.
You should have goals to achieve, so basically choose the branch according to your interest only.
Scope of all branches are same, but slightly differ.
CS have very good scope and has various option. You will have and more opportunities in private sector only. But, not much than in government sector.
Whereas, civil has much scope in government area, rather than private area.
Electronic and mechanical have good scope in both private as well as Government sector.

NCERT books are best for JEE preparations.

First of all, you have to score above 80% in 12th. Then, you should crack JEE Mains and JEE Advanced with high scores. Get into the top spot in counselling and that's it.

Both are better but IIT, Bombay gives better placement than IIT, Kanpur. The infrastructure of IIT, Bombay is also better and it is listed in top 10 universities of India.

Based on the previous year's cutoff you have to score a minimum of 65 marks in your entrance exam.

No. JEE Mains rank does't matter at all. The key is only JEE Advance Rank to open the lock of IITs.
