I'll get atleast 64 marks atleast. but I got 51 marks. :( same happened with accounts .I thought I'll get 55-60 but got 46(attended 86 marks)... here comes my weak subject.. iT sm . from day 1 onwards I'm worrying about this exam.. I hardly attempted 66 marks. and I hoped I'll get between 35-40 prayed god (should get 40) but I got 29... omg... I'm totally depressed. my final attempt is due on this November.. I should anyway pass by this MAY to appear for November final.. at the dirtiest thing is RELATIVES phone calls.. what should I do?? how to write. is correction strict now???
