Warm wishes for choosing such a great college options for further studies. Birla Institute of Management is as you know a very prestigious institute in India but Welingkar or WeSchool is also equally compatible. This is because this Institute has a handful of good faculties, and after completion of courses associated with placements, you will receive bunch of good jobs through the campus drive. Whereas in BIMTECH, placements are good but the fee structure of the courses are quite high,
