Progress reports and easy to navigate screens abound as the user studies for and takes examinations on the site. Courses on the site train students for the CFA exams, Financial Modeling and Risk Management and much more.
Ankit Mittal one of the members of the EduPristine team was kind enough to give me a login to poke around and the site is truly nice to use. Visit EduPristine to see a demo http://www.edupristine.com, read their press release regarding Moodle 2.2, or checkout the screenshots below for a quick tour.
