The aim of the actual course was to understand most of the Qur'aan when you finish all 3 books. This course has been trial and tested- it definately is the best thing out there. Best thing about it is that it is free!
The lessons are based on a series of books called the Madinah Books 1-3. These are the books that are used to teach Arabic at the Islamic University of Madeenah, and is taught over a space of 2 years. If a person is serious and dedicates quality time- on a daily basis- will definately take him very very far in arabic.
