Hey,

See, One shouldn’t be disheartened upon failing in any of the subject in 12th standard. One may apply for re writing the exams or move on with some new courses.

Since maths is a main subject for a science student, I think you should apply for re-exam as it will be good for your future and for career.

If not, you can opt for any of the following courses-

Mechanical engineering 

Chemical engineering 

Electrical engineering 

Computer engineering 

There are various diploma courses for which you can apply for.

Thankyou!
