Hello,
According to 6.12 clause in http://www.brecw.ac.in/Cat_B_2020_21_Guidelines BRECW Category B admission notification 2020 there will not be any changes in the seat allotted once the admission is taken. So you cannot opt for internal sliding. If you do not wish to join in the branch allotted to you then you need to to record the decision on the statement that was given to you and sign it. The accompanying parent or guardian also has to give his/her consent by signing on it. You are then relieved from taking admission.
