Detailed lessons are organized by topic (Biology, Chemistry, Earth/Space, and Physics) and presented as "Micro-Units." Each micro-unit must be viewed on Adobe's Acrobat Reader, which can be obtained free via a link at the site. The micro-units required two to seven minutes to open or download. Once opened however they are very detailed lessons complete with photos and extensive reading materials.
