Brutal curve/straight scale in engineering

<p>So one of my classes had the following statistics:</p>

<p>Exam averages are 56 (30%) and 58 (35%)</p>

<h2>Grades: </h2>

<p>Average: 68 (top of B-)
Standard dev: 12.5 </p>

<p>94 - 100 A+
86.8 - 94 A
82 - 86.8 A-
76 - 82 B+
69 - 76 B
64 - 69 B-
58 - 64 C+
50 - 58 C
40 - 50 C- </p>

<p>How are the cutoffs determined using statistics? My prof is pretty much insane and it looks to me this is somewhat straight scaled. Super ****ed</p>

<p>lol 2 standard deviations above average isn’t even an A+?</p>

<p>1 std above average is a B+…</p>

<p>I wouldn’t really expect this sort of curve outside intro classes, pretty odd your professor is that harsh on grading.</p>

<p>yeah worse part is that this is an upper level ME course, probably my last class that’ll have a B- avg.</p>
