Worgan, although designed for writers, lends itself easily to school. The notebook can be arranged to organize the courses that you take each semester (use the Student Notebook Scheme, see here).
Also each Worgan page can be exported to another Knowl-Edge program called Quizzer (see Export). This means you can create self-tests using Worgan.
The timeline can be used to arrange facts for a history course. The biographer page can be used to keep track of famous people (and then these people could be exported to Quizzer as explained above).
The reminders can be used to help you prepare for exams and remember all the little things that you may forget (like birthdays). Using Worgan's finances section can help you keep track of your expenses and help you maintain a budget.
Site-licenses are available and give you a large rebate when purchasing large quantities of Worgan.
