Anyway, even if the panic is for the former reason, I still don't see any reason for panic. After all, its just a result. Agreed its the TENTH STANDARD RESULTS. So?????
What can happen worst of all?? Of course, you are never going to fail the board exams. Believe me, its a lot tougher to fail in the board exams than to top them. So, worse things worse, you get say 70%. So what? You will go to a not-so-good or not-so-popular college. Well, if you are worried about not getting to 'hang around' in the 'cool' places because of your low percentage, then I cannot help you. However, if you are seriously worried about your bad result, and you are worried because it might harm your future prospects, then you can stop. Because, you tenth standard percentage just won't matter. Just accept, 'Mistake made' and rectify it. Your not getting good percentage in tenth board exams won't have a bearing in which college you graduate from or which company you get an appointment letter from. When you go to apply for a job, what will apply will be the college or university you GRADUATED from. Not your junior college. So even if you get low percentage in tenth standard exams, you can make it up by scoring well in twelfth standard exams.
Its not the end of the world.
However, if you are worried about you results with the fear that you won't get to 'hang around' in the 'cool' places then as I said, I can't help you. Nobody can. You can consider yourself to be seriously irresponsible, or filthily rich, who is going to spend his life just SPENDING the money that his/her dad earned. If you are just irresponsible, then you are in serious trouble.
So advice to you guys, just chill. There is no need to worry about the results because it won't have a bearing on your career.
