If SRM opens total number of seat for BBA is 120.
And now through SRM entrance exam 60 candidates got 100% score and fulfilled the required criteria to secure for free admission.
And the other side 150 students with the mixture of not even 60% academic score in +2 , SRM will select 120 students out this 150 who are willing to pay donation and get admission.
Therefore here the funds is SRM will reject even though if you have scored good.
SRM prefer to chose management quota over the students with good academic background.
