BITS Pilani - Birla Institute of Technology and Science

Most probably u'll be able to get CSE

In my opinion, Bits has a better brand name than IIIT. Also CSE degree is preferred by some companies over IT. To decide, you should have a look at the companies visiting these colleges for respective branches. Choose the college that gets your dream company. Also, if possible, talk to any Alumni of these branches in resp colleges.

You are eligible for bits . but for jee advanced ur eligibilty will depend on ur jee main score that whether u have cleared the cutoff of 100/360 or not

ranking of bits is 4th in 2016 skilled vit is in 6th place but still vit is a college that u should absolutely go with

Both options of BITS Hyderabad BTech CS and IIST BTech Aerospace are equally excellent options. You can chose any based on your interest to excel. (Lot of student do CS but rare prefer Aerospace. Why do not you try to be different? ).
