Beginner - From the beginning
If you walk into the living room and someone's watching a good movie that you have not seen, then it might be a good idea to try your luck and request the film to start from the beginning. You will learn to say this in Arabic along with other useful phrases.
Also, I love the dialogues, transcripts, and exercises. Everyday I look forward to doing more lessons. What a great learning resource is ArabicPod.net!!! Thank you for this obvious labor of love.
