<p>What's that mean? My AP Bio teacher said she might do that but I don't know what it means. Everyone in the class was like ohh man, dont. But I don't know what it means??</p>
<p>curving usually a good thing. There are many different ways but usually what happens is that if you score a 70%, your teacher will curve it up to a 80% or something like that. She could also curve your grades down. If she wants say 50% of the students to get As, but 75% got a 90+, then she would curve some of the people down to a B.</p>
<p>Curving generally means that the highest score in the class becomes the "100" or highest amount of points possible. For example, if the highest score in the class was an 80 and your score was a 60, then you would have a 75% C rather than a 60% D.</p>
<p>As was said, curving usually just means that the highest score will count as 100%, and the rest will go from there. It's usually a good thing, not bad - except when you have students like me that break the curve getting 100% and then everyone else that did miserably just gets the score as usual :)</p>
<p>As everyone else have said, but to some it up it's different for every teacher.</p>
<p>There are actually a variety of curving methods. The one above me is probably the most common. Another one is that if the class average is low (let's say it's 75%), then a teacher and add 10 (or however many) points to everyone's score, so the average bumps up to an 88. However, this method is less common, and tends to greatly favor the students that did well.</p>
<p>Because of that, the most common curve is the one above, because it helps students that didn't very well the most. I have also seen quadratic and even quartic curves from my math teachers.</p>
