IIST Thiruvananthapuram B.Tech Admission 2024

For eligibility, prospective students must hold a Higher Secondary Certificate (HSC) degree (10+2) with a minimum of 75% marks and possess a valid national-level (JEE Advanced) score. Seat allocation is determined based on this rank through the JoSSA Counselling process. Hence no you will not be eligible for this

if I score less marks or I failed in pre boards in one subject in class 12 ,so will it effect my eligibility criteria for jee mains and jee advanced for admission in IIST?


Your marks in Preboard doesn't matter at all. As you are awarded certificate /marksheet for your board examination only and not pre board.


It doesn't matter whether you get low marks in pre board or even fail in it, it's not going to affect your eligibility for jee advanced or   IIST  or anything else.

But still prepare well for pre boards so that eventually you can perform well in your  boards .

To help you further,

JEE  advanced eligibility criteria is given below :-

---------------------) Qualification required :- One needs to pass 10+2/ or equivalent with the following 5 subjects:-

  • Physics

  • Chemistry

  • Mathematics

  • A language

  • Any subject other than listed above

Those appearing for 10+2/equivalent are also eligible.

---------------------) Minimum marks in 12th /equivalent :-  you need to pass your class 12th with at least 75% marks in aggregate in class 12 if belong to general or obc category or at least 65% marks if belongs to SC/ST or must be in the top 20 percentile in class 12 examination.

††† IMPORTANT NOTE :- Considering pandemic in order to give relaxation. The minimum percentage barrier of 75 % - 65% in 12th board examination has been lifted off for jee advanced 2022. It means all you need to be eligible for jee advanced is to have at least passed 12th .

----------------------) 12th /equivalent passing year :-  You can give JEE advanced examination for the maximum of consecutive 2 years starting from the year of appearing for your 12th examination i. e to be eligible for JEE advanced 2022 your 12th board examination appearing year should be either 2022 or 2021


Considering pandemic, there's one time measure for students who had passed 12th in 2021 & 2020.

  • For 2021 passed :- Those 2021 passed students who had qualified jee main 2021 and had registered for jee advanced 2021 but couldn't appear in the examination are directly eligible for jee advanced 2022 without appearing in jee main 2022.

  • For 2020 passed :- 2020 12th passed students are also eligible for  jee advanced 2022 after qualifying jee main 2022 provided they have appeared in only one of 2020 or 2021 jee advanced or none of them.

Details about it is available at:-

-----------------------) There is upper age limit, according to which to be eligible for jee advanced 2022, you should be born on or after 1st October 1997. There is 5 years of age relaxation for SC, ST and PwD so candidates of SC/ST /PWD needs to be  born on or after October 1, 1992.

-----------------------) you must qualify JEE main  2022 to be eligible for jee advanced 2022.

How to get admission in IIST ?

Hii There,

Admission to undergraduate programs operates through a counseling process, with selection primarily driven by merit and adherence to the government's reservation policy.

The process begins with candidates completing online registration via the IIST website. Following the conclusion of registrations, IIST compiles an admission list. It's important to note that only those who have registered online are deemed eligible for inclusion in this list.

For BTech and BTech Dual (BTech+MS/MTech) programs, the selection hinges on the candidates' valid JEE Advanced scores and participation in the counseling round.

For more inforamtion, please refer:

can we join isro studying in other institute other than iist?


There are several ways to join ISRO as a scientist besides JEE Mains or Advanced. The fact is that ISRO directly hires students from IITs and IISC, making it simpler for you to get into ISRO if you attend one of these institutions. You would still be qualified for a position with ISRO if you studied engineering at any other reputable institution. You will need to study hard and gain the necessary information to be as productive as an IITian. To join ISRO as an engineering graduate, you must pass the admission test held by ISRO. ICRB (centralised Recruitment Board) conducts the test, and the GATE exam is also used for recruitment.

If you visit their official website, you may get a better sense of the eligibility standards and other specifications. If you didn't pass the JEE examinations, it's no issue; just get an engineering degree from a reputable university and start preparing for these entrance tests concurrently.

Good Luck!!

Does IIST has separate gate exam or the common exam

Hey Aspirant,

There is no separate entrance test for admission into IIST. You can get into the institute based on your JEE Advanced rank only.

Hope this is useful.

can I do msc physics in iist after doing bsc physics honors...if yes what is an entrance exam I should give for the same

Programme in Physical Sciences is through the Joint Admission Test for M.Sc. (JAM) and Joint Entrance Screening Test (JEST) followed by an interview (of those candidates who are short-listed) at IISc. .

Hope it helps you !!

Thanking you!!

if 75% is not there in 10+2 but average rank like 50% in jee advance these students are eligible for in IIST Trivandrum

That would be challenging because applicants for the B.Tech programme at IIST must have completed senior secondary school with an average MINIMUM of 75% marks from a recognised board and must have studied Physics, Chemistry, Mathematics, a language, and a different fifth topic.

The candidates selected in the course are based on the both 10+2 merits and JEE Advanced scores.
