<p>Curves are more generous than that. If that were the case, the average grade would be more like a C+, rather than the more common B or B- listed at <a href=“https://schedulebuilder.berkeley.edu/explore/department/FL/2013/27”>https://schedulebuilder.berkeley.edu/explore/department/FL/2013/27</a> .</p>

<p>They are unlikely to target that low a test average (and such a low test average would be curved to a B or so after the fact), since it is generally desirable in curve-graded courses to have well distributed scores (probably centered around 50/100) rather than most of the scores compressed at either the top or bottom.</p>
