Dear Student,

With 314 marks in the NEET 2025 Exam and under the SC category, there are very low chances of getting admission in govt or private medical colleges in Tripura. The cutoff of the state usually falls around 400. If you do not get a seat through Tripura NEET Counselling 2025, you are advised to consider private colleges outside Tripura with lower cut-offs.
