I don't understand how that's true.

<p>Think of it this way. In high school, if a bunch of other students in the class know the material better than you, that doesn't affect your grade. With the minor exception of team-based projects, your grade is solely determined by what scores you got on your exams, your homeworks, your papers, and so forth. However, you know what score you need to get whatever grade. Most high school classes use a simple straight-scoring system, where getting an average of 90% on your graded work will get you an A. It doesn't matter if everybody else got a 100 on their work. You get a 90+, and you get an A.</p>
<p>That is entirely different in curved Berkeley courses, which comprise the Berkeley engineering weeder courses (among many other courses). In these courses, the performance of other students DOES affect your grade. That is because the grading is based on the grade curve, which inherently includes the performance of the other students as an endogenous variable. So if other students do better, you * actually do worse * because you get pushed down on the curve. </p>
<p>Let me give you an example. I know a guy who got around an 80-something on a weeder exam. Pretty good, right? Wrong. That because the average score of all of the students on that exam was around a 95. Hence, his grade actually translated into a grade of, at best, a D, and probably an F. Sure, he knew most of the material on the exam. But that didn't matter. What mattered is that he knew less than the average student in that class, and THAT is what ultimately determines your grade. You can know the material of a class extremely well, and flunk the class anyway, just because everybody else knows it even better. </p>
<p>To give you another example. I know another guy who got a 30 on his engineering exam. But he celebrated. Why? Because the average score was a 25. So his apparently terrible 30 was actually worth an A. It didn't matter that he knew almost nothing on the exam. The only thing that mattered was that he knew more than the average student (and the average student knew almost nothing too). </p>
<p>In other words, it is your * relative * score that actually determines what grade you get. Your grade is inherently affected by the performance of the other students. Hence, this is inherently a zero-sum game. The better that other students do, the worse that you do, and vice versa. This stands in sharp contrast to high school where grading is not a zero-sum game, and where everybody can (in theory) get a good grade. In Berkeley engineering weeders, some people have to get bad grades. You just don't want to be in that group. </p>
<p>What that also means is that you actually * want * the other students to do poorly. This is why they say that Berkeley is cutthroat - because the weeder curves actually induce students to want others to do badly, because they know that that the worse other students do, the better they will do. </p>
<p>And some students do more than just 'want' other students to do poorly, they will actually try to make it happen. For example, there are stories of students deliberately telling others the wrong information so they get questions wrong on the exam. There are stories of students tearing out pages of library books or course reserves so that other students can't read them. There are stories of students deliberately trying to ruin other students' lab experiments so that they get bad lab grades. These stories are most prevalent among the premeds (who are cutthroat by nature), but are also not unheard of among engineers, especially in the weeders. </p>
<p>Consider a situation where there are 10 starving men, and only 9 slices of bread handed out (and you can't share the bread). Each man is going to be desperately fighting to make sure that he's not the one that's left without any bread.</p>
