HI,
Big Data is now trending and reached a very high level in the computer science field. Sorry, but you cannot get a seat for Big Data.

Sorry, no chance in IIIT Delhi with this rank. Your CBSE score is good but, your JEE rank is not good for admission if you want CSE.

Hello Bishal, If I may say so your rank in WBJEE appears to be a bit on the lower side. However to help you I am attaching a link that will predict college for you. https://www.shiksha.com/b-tech/resources/wbjee-college-predictor.

No, you cannot appear for IIT after this much time. You need to do some other course.

Go for the branch in which you are interested. Think about the college after that. You have to learn that for 4 years. If you choose any non-interesting branch, then you can't do good. Go for interest, not for placements. Don't worry about new or old. You can apply for jobs outside also. So, choose the branch first.
Best of luck.

Here is the State wise list of Castes that come under OBC category (CENTRAL),. If you do not send a valid OBC-NCL certificate, you will be considered under the General category. From April 2012, Socially and Educationally Backward Classes-Minorities (SEBC-M) isan additional category under OBC-NCL. So, this will be considered.

Im really not sure about this,as far as I know it may be in between 8.5k - 24.5k for OC/general category in EAMCET(considering all the four branches).
As you know, this ranking preference changes according to gender and caste grade, it fluctuates every academic year.
If your rank satisfies here, you will get admission.
