I have passed my hsc in 2018 I have to improve my marks in one subject can do so plzz suggest me??
Yes there is a thing called improvement exam but its not available every where.
Look around and see who/ where you can give that exam near you.
It is an option many kids take lile who want to give entrence exams. To get good marks in certain exams.
I hope it helped you.
Thankyou
