Actually I am giving improvement next year and by mistakenly during filling my jee form I wrote my 12% as 58 and it was 51 so it okk ????
It's not ok.As you have entered wrong percentage of your class 12th board,you need to correct it.You can correct it in the month of january when there will be a link present on jee mains website for correction.Till then keep regularly visiting jee mains website.
