Hello,

Since you said that you received a 98 percent in your boards, I'd like to inform you about Sastra University does not have a cut-off because the college officials will construct a merit list. You will get admitted to the college based on this merit list. JEE mains get 70% of the weightage, whereas 12th boards receive 30% of the weightage.

Moreover, it is dependent on a variety of criteria such as the number of students taking the test, the number of available seats in the college, and the level of difficulty of the JEE mains exam.
