     1== Identification of course elements ==
     2
     3A course can change over time.
     4Elements (lessons, exercises, sets) may be added, deleted, or reordered.
     5
     6A student has a "context" in a course - a sequential position,
     7and a set of review items.
     8What if the course changes, and these items change or disappear?
     9
     10Each element may be given a "logical name".
     11For items, this defaults to the file name.
     12
     13A user's sequential position is stored in the DB as the logical name
     14or last item viewed.
     15On continuation, Bolt looks up that item.

     17== Implementation notes ==
     18
     19At the implementation level, an exercise has three functions:
     20
     21 * When invoked with $mode_show set, it shows the exercise.
     22 * When invoked with $mode_score set, it computes a score based on the responses stored in $_GET, and assigns the score to $score.  Its text output, if any, is ignored.
     23 * When invoked with $mode_answer, it shows and "answer sheet" based on the responses stored in $_GET.  If the response is correct and no answer sheet is to be shown, it sets $no_answer_sheet.
     24
     25Bolt's exercise primitives perform all these functions for you;
     26however, you're free to implement your own exercises.
