German tutoring for secondary level student (regular, at home) and long gymnasium preparation

Hello, I am looking for regular German tutoring for my son, who soon would be starting his secondary school and would need help to also prepare for long gymnasium preparation. The lessons should take place at my home in Birmensdorf. Specifically 2 days per week with 1 session each day. The available times are noted in my profile but open to suggestions. We would like support with school topics, homework, and general language skills required for Gymnasium. The goal is to build confidence and keep up with class requirements. I would appreciate a patient and clear teaching approach. If you can support for Kurz Gymnasium exam preparation along with School please get in touch, Thank you, and I look forward to hearing from you.
