My father asks me several times that whether these marks are right or you tried to miss guide us, i said no to them. But now, the most worst time of my life has come my result date what to do, how will i confront or else my father kill me. Please try to help me out. Give suggestions.

You are in VII dude. You need to study hard. Otherwise your career will gone just down. You need to focus more on studies other than the time you spend on activities by which you fail the exams.
Please study hard.
