Hi Neelam.G.
What is this about, 1) is it the job of valuation of answer scripts of university exams? If this university job then norms fixed by the Controller of Exams should be consulted.
2) is it a private affair ? 3) does this cover the remuneration for valuation & re-valuation or re-totalling and to & fro expenses etc.
