That's a possible partial fix, but I recall plenty of classes in high school and college that had a weighted grading scale.
Done every homework assignment and aced every test all semester but then bomb the midterm or final? You're still in trouble. Also vice versa - if you didn't do any homework all year, but the midterm is going to be worth 90% of your grade anyway. And of course we all know there are teachers that are just notoriously harder than anyone else where no one is going to get an A in the class, so there's also an aspect of how well other people have done on the assignment/in the class as a whole.
None of that is new at all, though. The problem is that technology has now calculated out a number and displayed it and we as humans add more importance to that hard number. To me it's similar to the whole "fake news" thing - we're too inclined to glance at what the app on our phone says and not think any further.
