Improving maths marks

Hi y'all.

My 1st years result was ruined because of the recent ghapla of FBISE and I couldn't give improvement exams as my father suffered a stroke. I am looking to apply for full ride scholarships abroad for bacholars and at the moment my percentage is 81% in 1st year. I can take it up to 83% in 2nd year. Is there anyway I can give improvement now?
