It's the same as if he had made exacly 65 on the first three tests.

He will make the highest grade possible if he makes 100 on the fourth
test.  Then his grades would be:

Test #1:  65
Test #2:  65
Test #3:  65
Test #4: 100
------------
Total  : 295   
              73.75   
Average:   4)295.00
             28
              15
              12
               3 0
               2 8
                 20
                 20    
                  0

Round 73.75 to 74
