WordPress Exam plugin

The project I'm panning to do will be study and exam-site, built on WP. Blog-content will be used for daily news and messages. Page page-type will be used for the whole hierarchical structure of the themes/lectures - managable trough WP-admin - all data will be stored in the database - the plugin should be able to work on a fresh wp2.3+ installation, no core patching - a question could belong to more than one quiz. - any page can have any number of quizzes as sub-page - any quiz can have any number of questions - any question can have any number of choices - choices are dependant to the questions, each choices can only have one parent. - each quiz can have a timeout value, if set, the quiz will be time-restricted - scoring based on right and wrong answers plus time, if used on that quiz - each question could have an image to be displayed below the question - each quiz could have result-contents for score ranges, - each quiz should have a flag of enabling the retry of the quiz or disabling it - a global variable of number of questions each time to be displayed (e.g. 4 questions on a page) - if paging is used, page numbers/total should be dispalyed for the quiz - each users participation will be recorded, scoring, date participated and timing, - if retry is enabled, each participation will be seperately saved - if retry is enabled, a number of retrys and percentage-based subtraction will occur - a flag to make the quiz free or permission based to participate - statistics for each subject, quiz, question and user - protection against cheatings not mandatory, but would be great: - a global flag for the system; if the user failes a quiz, next quizzes should be disabled to him - ajax would be great to pass results of each question to the user. - questions and answers should be seo-friendly (not requested per ajax) ## Deliverables 1) Complete and fully-functional working plugin(s) 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
