Hi dear ,

              You may get seat in sastra university as the university does not release cutoff only JEE Main basis. In other words, the cutoff is not available officially, however, the candidates have to be in SASTRA B.Tech rank list which is prepared on the basis of JEE Main scores+normalized score of class 12th marks. 70% of the seats at the university are offered under this category, while 30% seats are offered on the basis of candidates performance in class 12th wherein they have to secure at least 60% aggregate marks in PCM. 

All the best
