Hi,

Hope you are doing well.

IIST offers admissions to its programs based on 2 method. One is through JEE Advanced and other through seperately preparing IIST Rank . Following are the cutoff based on IIST rank in 2020.

Branch name -  Opening Rank -  Closing Rank

4-Year B.E./B.Tech. Course

• Aerospace Engineering: 152-  473
• Electronics and Commnuncation Engineering with specialisation in Avionics: 206 - 511

5-Year B.Tech + M.Tech. (Dual Degree) Course

• Engineering Physics with M.Tech/MS in any of the listed specializations: 271 - 521

From above, it seems you have good Chances of getting admission into your desired branch. However the cutoff changes every year so if cutoff remains similar then you could get your branch of choice.

I hope this will answer your query.

Thanks!!!!!
