10 day trial                     $10.00   10 day membership which allows you access to all of the Physics Topics and all of the Mathematics and Calculus Topics. This option is for those who anticipate only short term use of the site - perhaps to prepare for a test that is less than 10 days away. Our other membership options offer much better value, however.

1 Month Membership    $20.00  1 month membership which allows you access to all site content which includes Physics and Math Topics plus the E-Book "The Exam Secret". Membership lasts for one month starting from whatever date you sign up.

Extended Membership  $49.00  Includes access to all site content until Dec31, 2010. This membership offers our best value for those taking physics until the end of the year.

1 Year Membership        $75.00  1 year membership which allows you access to all site content for an entire year starting from the date you sign up. The best deal for those who have two semesters of physics ahead of them.
