Hello Aspirant,

After completion of graduation course in B.Sc in mathematics and that too with hindu language is a little problem for you in terms of getting job .Today the most important thing required for getting a job is knowledge and fluency in english language.
You must have basis knowledge of english and you should be atleast able and speak in English.
After graduation in mathematics you will not any have amy option for diploma in mathematics field.
And if you will switch to course like Diploma in digital marketing, Diploma in Hospital Administration, Diploma in management,packaging, marketing,catering,etc.
But for pursuing any of these courses you should have basic knowledge of English.

I hope this helps.
