Hii saruchi
The best college for pursuing Bachelor's in management in Mumbai is the St Xavier's college Mumbai. It is also one of the best colleges in India for the same. It offers Bachelor's in management studies rather than Bachelor's in business administration. Though both of them are the same subject wise. It has an affordable fee structure and hostel facilities too. You can apply and appear for their entrance test. The entrance test is held only in Mumbai. It is a 1hr 30 mins test. And followed by an interview. For more information you can ping me up.
Hope it helps.
Thanks!!!
