-== Memory refresh ==
-
-Bolt offers a ''memory refresh'' system that periodically repeats exercises
-and, if necessary, lessons.
-Memory research suggests that this is necessary for students to shift
-learning to long-term memory.
-This mechanism works as follows:
-
- * A sequence of ''inter-refresh intervals'' is defined.  For example, (7, 28) means that an exercise should be repeated 7 days after it is first taken, and then every 28 days thereafter.
- * Bolt provides a function that returns the set of items, for a given student, for which refresh is due.  Your course can use this function to implement a "Review now" button on web pages.
- * Bolt provides a "review mode" in which the student is presented with exercises due for review.
+== Exercise set ==
+
+The 'exercise_set' structure specifies a set of exercises and a value 'num_to_show'.
+This number of exercises is chosen randomly and administered.
+
+Optionally, one or more '''review''' attributes can be given.
+Each specifies a grade threshold X and a list of review units.
+If the student's grade on the exercise set is less than some Y,
