Dear aspirant !

Hope you are doing great ! Sorry to hear that you couldn't get good marks ,but don't get disappointed ,a lot of opportunities are waiting for you . If you are 100 percent sure that you were a bright student and should have more marks then simply get your exam copies and send them for rechecking all this procedure will be told by your school authorities ,if you are fully confident , it may solve your problem .

Hope it helps you !

Thank you
