In St Joseph College how many percentage marks are they expecting from the 12th grade?

According to one of my friends studying at St. Joseph College, the cut-off score here is 75 percent, and three lists are announced every year by the college.

• The first one is for students who have acquired a score of more than 90 percent. 
• The second is for students who have acquired a score between 80 and 90 percent. 
• The last list includes individuals who have scored above 75 percent. 

The third list is for the students who scored above 75%. Although only 3 or 4 students out of ten who score 75 are shortlisted, based on their scores in science and mathematics. 

The first list is usually declared in the middle of May. The second list is published at the end of May, and the third list is released in the second week of June when the first week of college has begun.
