Revaluation class 10

So basically I gave boards the previous year and was very happy with my sst exam was expecting 75+ but when the result came i was shocked i got 69 marks so I ordered my answer sheet and this so called checker cut 1 marks for every question for no reason i wrote all points correctly maybe it was my handwriting and the person basically didnt give me full marks in any 5marker so I gave it for reval and guess what 8 marks got increased !!!! So I suggest you all to go for reval if you didnt get ur expected score and you are absolutely sure u deserve higher than these marks
