Diagnostic control was performed and examined to establish the effectiveness of the set of exercises utilized in lesson organization. The final exam revealed that the students’ communicative skills in the professional field have improved, their vocabulary extended, and they were encouraged to continue developing their language skills. The findings of scientific research are beneficial to young scientists, teachers, and students conducting research in this field.
