Add grades for Ex1 (midterm) , Qz1, and Qz2. If you missed a quiz guess an appropriate grade
(or interpolate from other quiz or midterm).

Total = Qz1 + Qz2 + Ex1 . Maximum is 325+50+50=425

If  350 =< Total < 425     --->  A range
If  265 =< Total < 350     --->  B range
If  200 =< Total < 265     --->  C range
If         Total < 200     --->  D or F range
