The number of studies carried out regards the effects of certain demographic variables on Foreign Language Anxiety (FLA) is rather limited in the English as a foreign language (EFL) context. Besides, the findings of these studies yielded differential results. This study researched the levels of FLA exhibited by Turkish undergraduates and effects of gender, age, and previous preparatory class experience on FLA at Ufuk University Preparatory School, Ankara. 124 preparatory school students have participated in the study. Data were collected via the Foreign Language Classroom Anxiety Scale (FLCAS), which was developed by Horwitz, Horwitz and Cope (1986) and adapted to Turkish by Aydin (2001). Scale administration was done via the Ufuk University online questionnaire system. Analysis of the quantitative data unveiled that Ufuk University Preparatory School students had moderate levels of FLA. Besides, age was found to be casting a significant effect on FLA. On the other hand, previous preparatory class experience, and gender were found to have no significant effect on the FLA levels of Ufuk University Preparatory School students.
