Dear Taby, though there is a correction window for AMU applucation form, Category is not one of the options that you can edit or correct your details. And that leaves you with no option but to appear as General Category only. Once the exam has been done, the next step is Counselling and admission and you cant change your details then. By then it is too late for anything. Once you realised your mistake you should have filled in a new form. Am sorry but you cannot make any changes later.
