## Assessment

A complete assessment package is an integral part of the site. This allows students to record their progress on certain pages, called o-tests of which there are 1,840 currently available, and teachers to maintain records of their student progress and use it for diagnosis, feedback and help. In addition teachers can use the site to create homework tasks along with hints and deadlines, all of which is marked on-line. To see typical pages, choose a syllabus then enter

**o-test**in the search box. See the online help for more information.
