Because someone got a 100, our teacher’s POLICY is that they wouldn’t curve everyone’s grades up.

I always hated this idea. I can explain why they do it, but I still don’t like it.

It basically punishes both the best students and the worst students. The best students get high scores, yay? I guess that’s fine but all their little friends will hate their guts. It’s a great way to ostracize people and tempt them to do worse. Even so, then the worst students never have a chance to increase their grade and are held back by the randomness of having 1 or 2 smart students unluckily in their class. Good luck next semester and hope there are worse students in your class? That’s not the best mentality either.

There are several other methods for encouraging students to continue working hard no matter if they are far ahead or catching up. And the grading curve is not it.

As the midterm is 20% of my grade with me having a 75 right now, I’m destined to take physics again for another term in junior year

That’s exactly what I mean. It’s a waste of your time to even continue trying and the best you can do is just sit there and treat your class as a prep class for the next time you take it since you can’t pass it this semester. Which is not the best way to teach a class as I suspect there are others the same as you. The classroom atmosphere will be different when some students are doomed to fail the semester but still have to sit in the classroom.

The reason why these teachers do this grade curve is because…well…it’s an easy way to cover their butts?

Imagine these two scenarios.

If all the students are failing or have low scores, the administration will take notice. Why is an entire class doing so badly? To get them off their back, the teacher curves all their grades. Suddenly all the students’ grades are average or great! Teacher gets to pat themselves on the back and administration leaves them alone.

Now imagine your scenario. I can only guess exactly but I’ll at least say some are failing, some are average, and 2 are perfect. The administration goes to the teacher and ask, “Why are these students failing?” The teacher can dismiss them saying, "No no no. Look. I have these 2 students with perfect scores. They all got the same lessons and materials. Those failing students are just the worst/lazy/need tutoring/don’t participate/insert excuses here/etc. So the teacher uses the high scoring students to justify the failing students. Therefore, there is no need to curve the grades at all. I mean, if they do, that would be “unfair” to the perfect students.

Sorry for the rant. There is so much I hated about the education system.

I’m glad you’re doing well in everything else. Have a nice break!
