After I finished my contract, I had a month to spare before enrolling at the main centre that I had decided to study in. So I decided to do a few weeks of private one-to-one at the markaz Arabe (or Arabi Center).
The Egyptian Colloquial went well, but the teacher was only half interested and a little boring. Probably not her fault as she was not a trained teacher, but the fault of the centre. I guess the director found her through her social circle.
The focus of this centre was really Modern Standard and Classical Arabic and for this I did notice a difference in teaching quality and enthusiasm.
My biggest issue with this centre was that they made a mistake with the dates on my certificate and when I mentioned it, the administration started to argue with each other and at the end of that they were rude to me and refused to make any changes.
