Hello sir, though your grades are very good but the only way to get admission is through neet. You can apply for the upcoming year to get admission.
Also if you want to apply for any particular states like assam then they conduct offline exams called AAU VET, for odissa OUAT, for rajasthan RPVT, for uttar pradesh UP veterinary entrance exam and BHU UET for BHU. You can check apply for these exams after checking their dates.
I hope this helps.
Thankyou.
