Hello Aspirant.

To get admission in IIST Thiruvananthapuram for B.Tech Aerospace Engineering 2026, you must qualify JEE Advanced with a good rank, preferably within the top 10,000–13,000 (varies yearly). You should have 75% marks in 12th (PCM). After JEE Advanced results, you need to apply separately on the IIST website (application usually opens around May-June). Admission is based purely on JEE Advanced rank + counselling. Focus on strong Physics, Chemistry, and Math preparation for success.

Good luck for your preparation.
