I took a graduate certificate course after graduating from uni more than 10 years ago, and boy did I have a fresh perspective!
"Stop thinking as a student" is telling the students that there are better goals to strive for, and it's for 2 kinds of students: one is those who won't study until before exams, the other is try-hards that ONLY focus on grades.
Grades are benchmarks of how you performed in school, but it's an inaccurate one, and it's a baseline one. For the students that are only asking to pass, they need to know passing means they are aiming too low. Passing is not too far away from failing. They need to aim higher because the world asks for more. For the try-hards, aiming at grades is also focusing on too small a thing, an incorrect goal limits the possibilities one may have. For both groups of students, they all need to know there are higher goals to strive for.
For me, grades was everything when I was an undergraduate. But this time for the postgraduate course, I never thought about it. There were only 4 units in my course, and since I chose only the interesting ones, I never thought about only passing, but rather what I've learned and how it can improve my job and my side hustle business. You know what, I got Distinction for all 4 units without ever bothering to "study hard", or even preparing for the exams. Yeah they are not 'High Distinctions', but I know I've learned a lot and I will do better at work. And it is improving my side hustle income.
So why bother focusing on grades.
