I also some translations are extremely suspect because I have found in no other source, and they do not occur in other Egyptian-courses.
Moreover, the vocabulary is sufficient relative to the lesson texts not, so you have to learn many sentences by heart, without understanding it.
The phonetic transcription is chosen to be very arbitrary and does not correspond in many cases the actual pronunciation.
Grammar refers to the general Arabic language and is in no way limited to the Egyptian one. It's the same grammar, which is used in Arabic-based course.
After the Arabic basic course, this was probably the last course, I have acquired from Sprachenlernen24.
