The paper analyses the relationship between pupils' performance in an English language test, response times, and whether the pupils study non-language sub- jects in English. The sample consists of secondary school 9th graders and pupils from corresponding grades at multi-year grammar schools (N = 1,347).
The results show that pupils studying non-language subjects in English spent significantly less time completing the test, have higher scores, but are also three times more likely to guess the answers.
