I've scored 73.7 percent in her mains obc category and have scored 100% in +2 can I get a seat in sastra university

Hello Dev . With your mentioned score I don't think you have cleared JEE mains therefore you are not eligible for admission on SASTRA University. The criteria for admission in SASTRA University is

Through stream 1:



Admissions to 70% of the seats will be made through stream 1 on the basis of JEE Main scores and normalized scores of the 10+2 or equivalent exam.



The 25% weightage will be given to JEE Main scores and the remaining 75% will be given to marks scored in 10+2 or equivalent examination.



The combined scores will be used to prepare the rank list and candidates will be invited for admission on the basis of the rank list.



Through stream 2:



The remaining 30% of the seats will be filled through stream 2



Only 10+2 (or equivalent) normalized scores will be considered while preparing the rank list of stream 2.



Hope this helps
