Yes, you can give your JEE Mains and JEE Advanced directly in the year 2023 without appearing in JEE Mains and JEE Advanced 2022. After clearing JEE Mains and JEE Advanced you will get admissions in IIST. The candidate seeking IIST admission in the B.Tech program needs to appear for JEE Main and Advanced and obtain a valid rank. Based on the JEE exams, IIST will publish the rank list for the option of filling and preference of specializations for the applicants. The candidates will later need to appear for the counseling.
