Srinivas, firstly I would answer the second part of your query. No, not all the students at any branch of BITS are rich, the students are not selected on the basis of their richness rather they get selected on the basis of their performance in BITSAT. So, if you are good enough to be in the merit list, it does not matter whether you are rich or not and moreover, education is a leveler between different sections of society and you should not divide it into rich or poor. Now, moving onto the first part of your query, there are many scholarships or fee concessions given to the students in BITS. Some of them are:-

* Students who secure the top three positions in class 12th exams in their respective boards are given a merit scholarship of 100%, 75% and 50% of the total first semester tuition fee respectively for the first semester.

*  Students who obtain 90% or above in the aggregate of the Qualifying Examination are given a merit scholarship of 20% of 1st semester tuition fee and the ones who have obtain 80% or above but less than 90% in the aggregate of the Qualifying Examination are given a merit scholarship of 15% of the first semester tuition fee.

* Students who have participated and won medals in International sports tournaments are given scholarship of 50% of the first semester tuition fee and students who have participated in the International sports tournaments are given scholarship of 15% of first semester tuition fee and the students who have participated and won medals in National tournaments are given scholarship of 20% of first semester tuition fee and students who have participated in National Tournaments are given scholarship of 5% of first semester tuition fee.

* The candidates who are selected on basis of BITSAT with a score required for a concession(generally decided by BITS before the examinations) will be offered a 25% concession in the Hostel fee for the normal duration of the programme (four years) or for the first year.

These were some fee concessions which you can avail while at BITS. Also, I would advise you not to think about the richness or poverty of your peers as it is the education that matters and in that case BITS is quite rich in education.
