Most of these pages make extensive use of Javascript.  Therefore they require Netscape version 4.05, or Internet Explorer 4.01 or better.  They are best viewed at a resolution of at least 800 x 600.

Several of the pages have quizzes that can be printed by your students.   The quiz is scored, if they use the print button at the bottom of the quiz (if they just print it as a web page, the quiz is not marked).

There is nothing to prevent a student from taking the quizzes over, and over.  If they do the number of times printed is shown, so you will know that they have done this.

Cookies are used to store the students answers to the quiz questions (for 10 days).   In this way, when students leave the quiz, and come back to it at a later time they will be able to retrieve their previous answers.  When the student comes back to the page he/she is asked to verify his/her name.  In a multi-user environment, where several students may be using the same computer, you may want to disable the ability to use cookies on your web browser, so that one student does not get another student's answers.
