Benazir, you will have to guide your teaching and your partner. Most of people don't know how to teach. They can only speak to to (chatting:)) and answer your questions. And when you speaking to a beginner, there is a problem: if you speak your langauge the beginner doesn't understand you. If you speak English she understands you but it is English:(
Arabs study Fusha in schools so they can offer some guidance, but mosly it is you who explain them what should they do to help you. Or there will be just "chatting without reason". Maybe "chattign about Arabic grammar" without reason.
