Each year, the CDSC offers students in grades 10 and 11 the opportunity to participate in an additional preparatory course for the Cambridge C1 Advanced exam. Led by Debbie Kramlich, this course is a special elective offered by the school. It helps students further develop their English skills to a high level and prepare specifically for the internationally recognized Cambridge C1 exam.

Throughout the school year, students undergo intensive training for all sections of the exam. They practice for the oral exam together, write numerous texts, and regularly work on exercises covering Reading, Listening, Use of English, and Writing. We are proud of the dedication and hard work shown by the participants from the previous school year and congratulate them on achieving their Cambridge language qualifications.

The official Cambridge exam takes place at the CDSC every June. External examiners travel from Bangkok to the CDSC to conduct the oral exams. This allows our students not only to prepare for the exam at the CDSC but also to take it within their familiar school environment.
