Grade Cutoffs
-------------

Grade cutoffs are approximately as follows, where :math:`\mu` is the
class average, :math:`\sigma` is the standard deviation.  These
thresholds are not guaranteed, but they rarely change by much.

.. math::
   &A+:\min\left(0.99,\mu+1.5\sigma\right), 
   A:\min\left(0.94,\mu+0.5\sigma\right),
   A-:\min\left(0.90,\mu+0.25\sigma\right)

   &B+:\min\left(0.85,\mu\right),
   B:\min\left(0.80,\mu-0.75\sigma\right),
   B-:\min\left(0.75,\mu-\sigma\right)
   
   &C+:\min\left(0.70,\mu-1.25\sigma\right),
   C:\min\left(0.65,\mu-2\sigma\right),
   C-:\min\left(0.60,\mu-2.25\sigma\right)
   
   &D+:\min\left(0.55,\mu-2.5\sigma\right),
   D:\min\left(0.50,\mu-2.75\sigma\right),
   D-:\min\left(0.45,\mu-3\sigma\right)
