Hi Karthik,
I understand that you believe that there has been some discrepancy with the evaluation of your papers and earnestly believe that your marks should increase. If you are certain of this scenario then I would suggest you go visit the official website of Karnataka board and check if there is any link for the re-evaluation of your paper. Although I believe the link has been deemed inactive by this time or has been removed. I would thus suggest you write a formal letter stating your issue clearly and post it to the Karnataka Examinations Authority and request for re-evaluation of your paper.
BEST WISHES!
