"George and Rawad"
Is this not missing the "uu" character for "and"? So currently says "George Rawad"
I agree. There are actually 2 competing standards for this. We, in Lebanon, put a space between وَ and the word after it, and I think it is be better for the course makers to adopt that standard in this case, because it's a lot easier for beginners to learn, and it makes adding hints and tips under words a lot easier too, because people can hover (or click) on وَ separately.
The options for this exercise include the character for "wa" (and) as part of Rawad. So the option is "andRawad". I'm answering "George and andRawad" and every time it tells me there's an extra space.
Next time, try answering just "George andRawad." Other commenters have mentioned elsewhere that in some dialects of Arabic, the wa/and is considered part of the following word, which is what you're seeing here.
This is the fourth time the placement quiz has used names. I don't think this is an effective assessment, and it is not checking vernacular vocabulary and has only checked the same syntax ("name" and "name") each time.
