Regarding admission in Bbau Lucknow

Hello all, I have some doubts regarding admission to bbau lucknow. Thanks in advance ✨

Is the registration fee is ₹500 per course or ₹500 for all cause it is showing separately.

Is there any other contact no. for help cause that toll free no. never worked. I swear why even provide it if ain't anyone gonna pick it up.

Third, can my sister get a hostel in it? We live like 200km far from the main campus in UP with the general category. It would be much appreciated if I guys can give reviews also)).
