My life is screwed

I had gone to this computer symposium on a Thursday a few weeks back. So I had missed out on some prcatical work. Yesterday the teacher wanted to check the file and quite obviously my work wasnt complete. So I told him that can I give the parcatical file at the end o this period. And he says NO!! So because of that stupic competetion I have missed out on the checking of two practicals and that teacher wont even check it again.
