Hii goundegouda!

If your caste is 3b then it may imply that you are under OBC category. As in Karnataka, 3b is a subcategory within the other backward classes reservation system.

Then having 371J form offers additional benefits if you are hailing from historically underdeveloped areas - specifically the Karnataka Hyderabad district like Kalaburagi, koppal, yadgir Bidar and ballari. 371j form refers to a regional Kalyana Karnataka region reservation.

Therefore, you are eligible for region based reservation in addition to your caste baseed reservation especially if you are applying to the institutions which are located in or offering seats for that region.
