Hello. SASTRA University cut off for engineering is based on 2 streams

• Stream 1 for 70% of seats will consider both JEE mains score and 12th standard scores whereas stream 2 for 30% seats will only consider 12th standard scores.

• Applicants under stream 1 will be admitted to 70% of the seats based on JEE [Main] 2019 percentile score and +2 marks.  The weightage for JEE Main scores and +2 marks will be 25% & 75% respectively. The JEE Main percentile score and normalized +2 aggregate will be taken together as per the weightage and applicants will be ranked based on the resultant combined score.

  Recommended

• Applicants under Stream 2 will be admitted based on their normalized aggregate +2 or its equivalent marks. This is for 30% of the total seats

Since you have all the eligibility, you can get seat in SASTRA in either CS or EC branch. All the best...!
