Hi Sheron,

I am assuming you have provided me your IIST 2019 rank.

I can provide you 2016, 2017 and 2018 IIST rank cutoffs of IIST, Thiruvananthapuram for all the categories.

In 2016, 

Closing Rank- 497 (General)

Closing Rank- 185 (OBC-NCL)

Closing Rank- 106 (SC)

Closing Rank- 53 (ST)

In 2017, 

Closing Rank- 691 (General)

Closing Rank- 318 (OBC-NCL)

Closing Rank- 183 (SC)

Closing Rank- 68 (ST)

In 2018, 

Closing Rank- 1,336 (General)

Closing Rank- 508 (OBC-NCL)

Closing Rank- 252 (SC)

Closing Rank- 49 (ST)

As you can see, the cutoff has been increasing every year, so you still might have a chance if you belong to the General category.

Hope this helps you.

All the best!!!
