Universities in India tend to use different grading systems. For example, in one, a grade of more than \(90 \%\) for distinction may have its minimum passing mark at \(60 \%\). In another, a grade of more than \(70 \%\) may signify distinction, while the minimum passing mark is \(45 \%\). This makes a direct comparison of percentage grades among universities in India difficult. Why might this policy help or hurt students on the job market?
