Hello gopendra garg

I hope you are doing good . I would glad to tell you that for getting eligible for bsc maths hons course , you should have passed your 12th from a recongised board with some decent percentage like 50percent which is generally in every college with mathematics as your main subject . If you have done with specialized mathematics course , then you are elgibile for bsc maths hons too

Hope you found this answer helpful. Good luck for your future
