Dear aspirant!
Hope everything will be fine! If you want to take maths as an optional subject then there will no any issue.Believe me an IAS topper Kanishka Kataria also got AIR 1 with mathematics optional.But if you read maths till 12 then that is enough now you must revise all those things .Also you did good thing by take admission in B.A because now you had gained some knowledge about other subjects also.Be consistent ,give yourself at least devoted 1 year and believe me ,you will shine as a star.
My best wishes are with you!
Thanking you.
