Suppose that all exercises at the textbook or monograph level are divided into ten groups according to difficulty and assigned the numbers 1, 2, 3, ... from easiest to hardest. We then assign difficulty grade A to problems in groups 1--5, difficulty grade B to those in groups 6 and 7, difficulty grade C to those in groups 8 and 9, and difficulty grade D to those in group 10. In addition, one asterisk (*) corresponds to an estimated solving time of 30 minutes, while "#" indicates that there is no time limit.
