Hey aspirant,

That totally depends upon your hard work, dedication and focused mind. If you are still determined about your goals then of course you can get your percentile increased by the next year. So, it totally depends upon you. But if you want to take admission this year then on 90 percentile also you may get some of them. For that please refer to the cutoff link mentioned below-

But yes, if you are determined about your goals then nobody can stop you from scoring 99 percentile next year.

Hope it helps.

Good luck.
