Not really, not at my school. The top students do the work themselves (if it’s individual). They usually don’t ask other students questions, since it would probably mean POSSIBLY getting one question answered and in return having to answer 5 questions from another lower-leveled student.</p>
<p>The lower-tier students copy from the solutions manual. The middle-tier students work together, and do it at the last minute. Some go to the TA to see the homework being solved, if that’s considered working in a group. </p>
<p>Maybe it’s because I’m still only taking the early upper division courses. I think it will change in more advanced courses, and definitely in the graduate courses.</p>
