The total no.of engineering seats in BITSAT all three campuses are around 2000. The total no. of applicants every year on an average are around 3 lakhs. So. there is a lot of competition for BITSAT. The exam is a bit difficult and you need to work very hard to get a seat in one of the BIT's campus. The no. of students taken for BITSAT counselling are also very less since the intake is less.
Hope this helps you.
