Hello aspirant

Firstly if you have studied Mathematics in STD xii then only you will get admission in  BA economics hons. There are very few seats for BA Economics hons in BHU so cut out is very high. Most important thing you have applied for bcom, then they can give you Admission in BA economics hons only if there is vacancy for the subject at that time. So it's difficult that they will shift you from b com to ba eco have hons.
