Anna University — nov/dec 2018 results inadequate evaluation.

I'm vignesh bharath g (Reg
. No:[protected]-19 batch) studying mechanical engg., (4yr/7th sem) at velammal engineeeing college. Upon nov /dec 2018 results that have released on 14/12/2018, i assure that my maitenance engineering paper (Sub. Code:me6012)
Has been insufficiently (Incorrectly) evaluated with a 'd' grade may be due to some mistakes on evaluation. But i am sure i will score 's' or'a' grade in that paper.. As i from a economically backward background, i need to suffer a lot to pay rs.700/- for revaluation.. So, i kindly ask university to take respective and corrective actions to support poor student - s of our state... Please sir...🙏🙏🙏
