With a UR rank of 6138 in PCB, your score is beyond the usual cutoff range for government BPharmacy seats in Bihar, which typically close around 3000 for the unreserved category. Even your EWS rank of 835, though strong, is slightly outside the general cutoff range for EWS seats, which usually extends up to 800 to 900. Therefore, securing a seat in a government pharmacy college through BCECE is unlikely.
