I interested in mathematics my graduation second year what could i do

Hello there,

Hope you are well.
If you are really interested in mathematics,  I would suggest you to go for higher studies in mathematics,  M.sc mathematics is a reputed course and after M.Sc mathematics you would have a lot of available options open for you.
You can either pursue higher studies like M.Phil or Phd,  you can also opt for getting a government job like one in DRDO or in defense or you can aim for civil services.

Hope I am clear
