my commiserations to all who didnt make it this time,i agree that luck matters,or rather the intention of Allah for us,as we cant claim to be "intended" for anything as long as we believe that its He who controls our fate! but making the time period a person spends on studying criteria for passing is also wrong,everyone has different capability gifted by God! believe in hard work,if it didn't pay off this time it will come in handy for something else Allah intends for you
