<p>With regards to the professor saying “Sorry, can’t say” this isn’t necessarily something you ought to sat WT* to because curves might not necessarily be determined yet if at all. For example, at my university, Linear Algebra students may or may not get a curve bonus depending on the quiz and final grades by the end of the semester. So with your professor saying that she “can’t say” she may be refering to such a policy or simply that she is unsure whether or not a curve is warranted because perhaps while a few students got under 60, the majority got over.</p>
<p>Frankly, a flat curve regardless of student achievement or underachievement is simply silly. The only purpose of a curve ought to be to even out grades between different professors.</p>
<p>Also, many people who think that the course is too hard may simply give up part way (and thus end up with a 15) while others don’t give up and actively seek outside help and perhaps get a higher grade or even a 100. And while proofs are not necessarily useful for applying a certain formula or theorem, knowing why something is true can offer unique insight into the workings or a formula or theorem which can certainly bolster udnerstanding.</p>
