Why is this course so incomplete? By the time you finish it, you can hope to have learned only 0.1% of Arabic!
No arabic is really easy you know
It should also be right "ما الجديد"
I think if it was written "What's new" then it would be more clear. But literally, you're right (though no one usually ask what is new [as opposed to old or used]).
I don't see why you differentiate it is and it's. It's just a question of level of formality. But why is the article required in Arabic?
It's showing 'new' instead of 'news'.
