Add up the grades of HW1, HW2, HW3, Exam 1 (max is 66+66+66+335= 533 pts)
 If you skipped a HW substitute (extrapolate) accordingly

 Let G be this total
if
  400  <= G <= 535  grade is an A
  300  <= G <= 400  grade is a B+ or B
  250  <= G <= 300  grade is a C+ or C
  0    <= G <= 250  grade is a D or F
Boundary grades (eg 400,300,250 is a toss).
