After we get the photostat copy can we question for more marks again ?

Dear aspirant,it is not clear that what you are asking.Please mention clearly about your problem.If you are asking that after you get your Entrance exam result on photostat copy,then can you ask for more questions or marks.Then,I would say that it is not possible to get more Marks in Entrance exam once result is declared especially in JEE MAINS.There is nothing like revaluation.Because the papers are checked by computer system so there are no chances of error.If you want to know something else then please comment or post a new query so that I can help you.
Thanks.
