^^^nah dude, its absolutely fine.You can do that if you want.there are no records whatsoever.In fact, your 12 report card is the only validity to your giving the xam. btw, there may be a small hitch. When getting admissions in clleges, what would you use as your school name?? coz, you have to have the principal's sign and stuff from the school u have your reports from. then, you also need a transpher certificate and a migration from the school. They wont match, would they???
