Abstract
This study investigates the factors which affect the students' achievement in their examinations, mainly test anxiety. The effect of this anxiety was traced among Arab learners of English as a Foreign Language. The researcher used a questionnaire in order to get the necessary data about this psychological phenomenon. Data analysis was used to indicate that test anxiety is a natural psychological phenomenon that occurs due to lack of readiness or because of getting poor marks or grades. Moreover frantic reviews just before the test are more confusing methods than helpful ones. Students can reduce test anxiety through study habits and skills. Some recommendations were given to reduce these causes of anxiety.
