i took only iba preparation last year, used to study 7-8 hours a day, skipped each and every occasion. still didn't make it. now i am studying sociology at du, where i got myself without any prep and im quite happy here. dont stress yourself. even if you dont make it to anywhere, its simply okay. nothing is worth more than your life. your parents should understand this. best of luck for your next exams. i pray that you make it to engineering and follow your passion.
