Guru Nanak Dev University — Exam checking

Respected sir, as the results of 5th sem 2020 has declared on 17 june 2021, I'm not satisfied with the checking of mathematics subject. Bcz I did all of the ans and also correctly but I have got very low marks in that beyond my expectations. I don't have much money for rechecking also. How could we trust on Gndu checking. Even my classmates have got more marks than me even they didn't attempt the whole paper.
Kindly reduce the re -evaluation fee or re-evaluate and recheck all mathematics papers of 5th sem.
