Dear Sir or Madam,

I hope this am writing to request information about the language courses offered at the Success Language Centre, as advertised.

Firstly, I am interested in whether you offer German courses at your centre. Additionally, could you please provide details regarding the duration of the beginner-level course?

Furthermore, I would like to inquire about the frequency of classes and the scheduling options available for students.

Moreover, could you please furnish me with information regarding the fees for your courses and whether there are any discounts available for students?

Lastly, I am curious about the qualifications and experience of your instructors. Are they native speakers of the languages they teach?

Thank you for your attention to these inquiries. I eagerly await your response.

Sincerely, 

Trần Bình Minh.
