Based on my years of experience, I can guarantee that you can learn Arabic from the alphabet until you reach a good level to speak with native speakers in different topics with confidence in less than 60 hours. During the 60 hours, you will learn Arabic alphabet, introducing yourself, talking about your family and relatives, talking about where you live and places where you live, talking about studies and traveling, and a lot more you will get during the 60 hours, for sure!
