Dear Aspirant,

Its great that you want to make your career in Mathematics. You can do BSc Mathematics from any college if you have a good percentage in class 12th Board Exams. Most of the BSc courses offer admissions based on Merit only. After pursuing BSc you can go for masters in mathematics (MSc Mathematics). You only need to give entrance exam in when you have reached the MSc stage.

I advice you to aim at good recognized universities eg. University of Delhi etc.

Hope this Helps!

GOOD LUCK
