Hello student,
The NTA has considered your january score and not your september score in to account only because your january score is higher than your september score.If you haven't mentioned about your caste reservation in your january application then i don't think that you will be eligible for that reservation during the counselling and now i think that we won't be able to change that.The one thing you can try is that when you go for self reporting for accepting the seat, carry your ews caste certificate along with you and tell the officials there about the problem.Then they might help you in some way.
