BITS Pilani - Birla Institute of Technology and Science Answered Questions

Getting into BITS requires you to write BITSAT comprising of 150 questions of physics, chemistry, maths, English and logical reasoning to be solved in 3 hours. You need to have 75% aggregate in PCM to write this test. BITS is obviously good as it stands out to be 5th best engineering college in India including IITs.

The marks scored in BITSAT doesn't matter for scholarship in Indian campuses of BITS-Pilani. For Dubai Campus, scoring above 300 would be sufficient for 75% scholarship.
For Pilani, Hyderabad and Goa campus merit and merit cum scholarships are available. Merit scholarship is available to top 15 students of campus while MCN is applicable to those whose parents income is less than 7 LPA. Also, for MCN Scholarship, CGPA has to be greater than 8.5 for 80%, between 7.5 and 8.5 for 40% and greater than 6 for 25%.

BITS-Pilani would be the better choice if the interest of engineering discipline is towards computer science/ electronics as it has got stupendous placements in these domains. However, this doesn't imply that NIT-Surathkal has a poor placement record in CS/EC. Its just that, BITS has got an upper edge in these domains than NIT-S. If you want to go for core branches like Civil/Mech., go for NIT-S. The campus life of BITS is awesome whereas NIT-S has its own beach where students can tranquilize. Both the institutions are good and have their own pros and cons. I suggest you to select one as per your branch and preferences.
All the best!

BITS stands out to be the 5th best engineering college of India including IITs. Comparing a branch of college to other depends on the other options you have and is relatively tough. As even the students of manufacturing get into oracle taking away a package of 22 lacs per annum so you can't really compare a branch specifically.
Best of luck.
