Hello Somnath,

Yes, BTech final year students should be able to apply for MTech offered by IIST as the official website clearly mentions that Students who are completing their qualifying degree programme in 2018-19 will have to provide the consolidated mark list/mark lists of all semesters along with Provisional/Degree Certificate on or before October 31, 2019 which means it should not say that you are not eligible. Do check it provides graduating year like 2018-19 instead of 2019.

Hope this answers your query, feel free to ask for more info.
