Union Public Service Commission [UPSC] — I'm complaining about the way of checking for nda examination

I'm extremely dissatisfied with the way of checking of nda examination. As per your rules if the candidate isn't able to qualify the maths exam his/her gat paper is left unchecked. This is totally unfair how can you judge someone's calliber just by mathematics and if students from medical stream can appear for the examination then why the level of exam is so much high. This is also possible that a candidate may not have strong knowledge of maths but he/she has excellent knowledge of current affairs and gk. The indian army loses thousands of aspirants that have calliber just because of your way of checking.
So you should change the way of your checking the gat paper should not be left untouched if the candidate isn't able to qualify maths exam. The basis of qualification should be overall marks. And if you amend your method of checking i'm sure indian army will not lose some vikram batra's and thousands of aspirants that have the calliber.
