The Arabic course has many mistakes.
I am a native speaker of Arabic. I also had learned Arabic for 12 years in school. I've taken the placement test, and it is full of mistakes. First: Words in formal Arabic are pronounced differently according to their function in the sentence. Example: نام الطفلُ. الطفل in the sentence above is subject that's mean this is who did the action. The word here is pronounced with a soft (o) sound. but in the sentence below, the same word is a compliment. أنجبت المرأة الطفلَ. Here, the same word is pronounced with a soft (a) sound. In the placement test, the words were pronounced differently according to gender which is a different case. I know the Arabic course is in Beta test, but they should make people who studied Arabic test that course.
