I think it's terrible how universities reduce a student's achievements down to a single number (GPA) when there are so many factors involved. When I was at university, some students didn't have to work to earn money and they could focus on their studies 100% - That gave them an unfair advantage. I worked for the second half of my studies and there was an obvious, sudden decline in my grades.
