Bilingual education is more demanding than the usual parallel programme. The course is suitable for able and motivated students. Of course a feeling for language is important because the students are expected to learn English, both actively and passively, in a relatively short space of time. Students find it perfectly normal to use English all the time in their communication with both teachers and fellow students.
Factors that are particularly important are enthusiasm, motivation, perseverance, a healthy curiosity and a wide general interest.
