This research used "ex post facto" method, with responses collected from eleventh grade high school students in Jakarta. Respondents worked on tests with similar material, although at different times. Students' anxiety was measured based on behavioral and cognitive characteristics listed on the questionnaire given to respondents along with the English test. The results pointed out that there was indeed a difference of students' anxiety levels in working on the various English text comprehension tests given.
