From the developer:
onCourse allows you to track your students, courses, and enrollments comprehensively. With minimal training, your staff will be able to easily manage the most important information from across your organisation: Web site pages, students, enrollments, invoices, tutors, and much more.
Everything you need is there: a full general ledger system, right through to systems to make it easy to market your courses on the web, by email, SMS, or however.
