BITS at Pilani campus is very good education and exposure for life.
There is no reservation, however some financial assistance is given to students on need basis.
The internship system at BITS is the best in the country, perfected over a peiod of more than 40 years.
Only thing sto be kept in mind is that Pilani is a small place, have all facilities but not that of a large city.
BITS Dubai admission process is different and not as good as BITS in India.
Anyday I will recommend BITS in India versus Dubai
