Selection of school in jeddah

I could suggest BISEJ (Bangladesh not British international but I would definitely recommend if you got the spare money haha) the infrastructure is pretty bad, class conditions too and non-existent extracurricular activities but this school tends to have good IGCSE and A Level grades, apart from the previous batch but generally.

I could recommend Coral too, I believe the principle there was one of our old principle of our school who left due to our school condition (Who was known to be great, though I was not in school when he/she left)

Ps - He will probably be looked in a pity way and be bullied if he doesn't socialise well or have trouble socialising. (In higher classes, Yr7+)  I have a friend who I mistook as Muslim because he used to use the common Islamic phrases/words used here day to day. My guess being he developed that in his previous school as he got older (Plus he's the popular kid kind, so he is really good at socialising)
