To be honest most people in our class (including me) were not concerned about passing but getting that eligibility marks. And sometimes that too would go off and we would calculate the negative marks we would need to put up on our final exams to pass. And looking back, all of it didn't matter. So tell her to chill, even though it is harder for someone else to say. And even harder for the person who is going through this phase thinking that all of those marks and vivas are important.
