National Board Of Examination — About not providing neet pg answer key and conspiracy with transparency

For the better transperancy and better trust worthy relation with examination body.. they should provide answer keys after avery exam.. and there should be very little delay(of 1-2 days) in announcing obtained marks and all india rank simultaneously of all candidates.. I can't understand that even after it's being online and software based examination why they take much time in result announcement?.. and answer key always should be provided to candidates as they have paid for the examination(it's their right) and they should know where they have missed the answer and which were the correct answer..even the toughest o[censored]PSC exam also provides answer key then don't know why NBEMS is not providing ans.. currently we have to trust blindly to NBEMS, we can't even know our mistakes and directly provided by blind marks and after that all india rank and that even after much delay of approximately 1 month(25-35 days)
