Hello student

hope you are doing well and safe. With reference to your query,  I would glad inform you that BITS and moslty every private universities are very strict in paying academics fees . If you wont pay fees of second installment , you can be in trouble and they can charge you fine of late fees . However,  you can mail to hod requesting him to give some time extension and can expect some further delay bbut chances are less

Hope you found this answer informative. Best wishes for your future
