Hi Risit,

Due to some medical issues you have to leave college within one week of your admission then there are tough chances that they will be going to accept your candidature again as one week is not such a long tenure (to be more specific 5-6 days only as Saturday and Sunday are off). In 2020 you want to resume BDS from same college then it is better if you have a word with the college authorities and explain your scenario because your duration as a student is so short that they might have automatically cancelled your candidature if you had not informed them before taking break.
