I hope that this will help.

Yes! If you wish to take admission at IIST then you can take admission in it through JEE MAINS & ADVANCED 2023. The thing you should keep in mind is that, JEE ADVANCED 2023 is your final attempt and if you wish to go for the BTech courses at IIST, then its your last chance. So do prepare sincerely and thoroughly. As you know practice is the key, so you should focus both on problem solving and building concepts. Also it would be beneficial for you to appear for the Mock tests as much as possible & I hope you will succeed.
