The marks are considered depending upon the cut-off set for the individual year. Since the cut-off varies from one year to another, it is slightly difficult to put on a perspective without acknowledging the same. 

• As per the cut-off based in the year 2019, subjects like Physics, Chemistry, and Biology are considered for shortlisting purposes. 
• Apparently, the cut-off is evaluated on the basis of the following method, Biology + (Physics + Chemistry)
• The total marks are 200 and if anyone scores more than 193 in the exam, then they can easily secure admission at the institute. 
• If you belong to the open category and secure marks above 95 in every subject, then you can unquestionably grab a seat in the open category. 

It is best that you research thoroughly about the cut-off applicable for this year and decide whether or not it goes in your favor.
