Hey,

It's totally okay if you're not good in maths, as there are many people who ain't good either  and choose other things to do. There are plenty of options to pursue even if you no maths in your class 11th and 12th. You can opt for humanities, Art, Commerce and many other options are available to be choosen expect for maths after your 10th. And there are many courses you can pursue even if have no maths with you after 12th.

Ask me if you any further doubts.
