1)   Multiply   each   score   (as   if   it   were   out   of   100)   by   its   percentage.
68   x   .12
=   8.16
72   x   .12
=   8.64
80   x   .12
=   9.6
*( The   grade   you   have   is   most   likely   out   of   10,   so   multiply   by   10   to   figure   what   it   would   have   been   out   of   100.)
90   x   .10
=   9
2)   Add   all   numbers   from   #1.
8.16
+   8.64
+   9.6
+   9   =   35.4
3)   Add   all   percentages   you   have   a   grade   for.
12   +   12   +   12   +   10   =   46
4)   Divide   #2   by   #3.
Then   move   the   decimal   2   places   to   the   right.
35.4
/   46   =   .76956
76.956
is   the   average.
