If you click on the "Community" menu at the top of the iTalki webpage and choose "Language Partners" you will find lots of people who are looking for the chance to practice with you. Just search for English or German speakers who are learning Arabic (so that you can help them in return).

Hello. My name is Milton and I am a tutor. I can assist you with learning English. Check my profile; perhaps, you would like me to prepare a class for you and if that is the case, you may book one of my classes. Take care
