Wiesbaden High School

I was wondering if anyone has had experience with the Wiesbaden High School, formerly the Dodds high school, as my daugther will be attending grade 11 there in the fall. Any feedback would be much appreciated.

I am moving to Germany soon to join my new German husband. I will be taking my son who is currently in grade 9 high school. He does not speak any German at all. The program of study which he is in at the moment in Canada leads to university entrance qualifications. I would like that he attends the same type of school in Germany (we will be near Koln). Does anyone know of the integration procedure for 15yr olds, if it is comprehensive in nature and if it will prepare and integrate a child into Gymnasium successfully if the child has no prior knowledge of German.
Thanks to anyone who can help me out.
