How much does a below-average student learn? (below-average just wrt a single course)

<p>So say, how much does a student learn in a course where he gets a 2.5 GPA?</p>

<p>I know that among those with 2.5 GPAs, there’s a lot of variability in the amount learned, and it varies from student to student and from course to course. But what do you assume about how much a person has learned, if you see a person get a GPA in such course? Certainly, it could be attributed to many factors - screwup on a single exam or a lack of learning. </p>

<p>And how much do you feel like you’ve learned from courses where you’ve gotten a GPA in that range?</p>
