exercises designed to test your understanding of the grammar points you have
just studied. You can access these from the bottom of each feature page.
(Microsoft Internet Explorer 4.0+ recommended). "Self-Tests" are available for
everything except Joiners.
Make certain that you let the "Self-Test" page load completely before entering
