hey shalini, are you talking about NEET or AIIMS, however for both the correction window has closed, so what i would suggest you to do is mail the controller of exams humbly stating your problem and if thats okay or you need to corret, if so request for a solution and am sure they will help you out, get me back to me with further queries and if you specify if its AIIMS or NEET i ll provide you with the mail id, good luck
