The best place to learn Arabic where ever you are is the internet. I have been studying the language casually for two years and can now have decent conversations now. I have tried many things but have found podcasts to be the most effective since they’re fun to listen to and convenient as they can be downloaded to any MP3 player. I highly recommend http://www.arabicpod.net, they have over 400 mp3 podcasts to download from, videos, apps and other cool stuff. All their beginner podcasts are free. Don’t give up!
