IBP has not enough resources to announce all the results at same time... the result of JAIBP is still pending as well.. which should have been announced by now...
plus by taking so much time in announcement of results they are making it more controversial.. and if SBP announce retest what about those who cleared the first test??? are they going to sit again??

Jo doosri ki qabliyat ka test lerahay??? un ki apni qabilayat per sawalye nishan hay???
