<p>"That is precisely my point. Grading scale doesn’t necessarily have anything to do with the difficulty of mastering the material. "</p>
<p>The curve can kill some and it seems if they want to encourage more students to take science/math classes, the curve isn’t a great way to encourage them. There is all this talk in the US that we are falling behind in math/sciences, etc. than you would want to encourage more. I don’t mean to dummy down the class, but when you see some classes with an average test grade less than passing, there is something a bit off. That is me, as parent looking from afar.</p>
