Regarding the ordering of the sheets:
If you already know what areas you need help with
jump right in at the appropriate sheets. Otherwise, the
first sheet "Working a Problem" gives a
quick run-through of an effective method of solving
a standard Astronomy problem. This first sheet can
serve as a diagnostic to determine which areas of the
process of solving a problem are most difficult for you.
Then the remaining sheets go into much more detailed help for
each of the component skills that go into solving a problem.
Sheets which contain practice problems are marked
with an asterisk(*).
