Hello there ,

Hope you are doing well . Most probably,your present  gap certificate will do the work . As it has been issued after NEET 2021 happened ,it is valid . You will require it during the documents verification process for admission in the college that you will be allotted through counselling . Generally, the validity of legal certificates like caste certificates , domicile certificates is one year . It can be  6 months too. It varies  . Also, different colleges can have different procedures and demands that will only be known once the admissions after alotment begin. It's advisable for you  to wait for the Counselling processes to commence.
