Let G be the sum of HW1, HW2, Ex1, Ex2 (503pts total)

 If the course was to end NOW,  grade G would have determined your group
grade as follows:

420 <= G <= 503      A range
350 <= G <= 420   B+/B range
250 <= G <= 350   C+/C range
 0  <= G <= 250      F range

Groups are overlapping.
The class average is around 370 of 503 so the scale as always is more
generous for you than curving
