The results of the research showed that students experiencing anxiety before taking a math test as the cause of anxiety is experience, intelligence, preparation, and family. Differences in levels of anxiety based on gender indicate that there is no significant difference between the level of anxiety experienced by male and female students but male students are more anxious than female students the cause is that there have been similar thoughts and goals in terms of achievement so as to make male students neither men nor women experience significant differences in anxiety levels. There is a relationship between the level of anxiety with learning outcomes of 0.43 which is in the category enough and has a positive relationship, namely the higher the level of anxiety, the higher the student learning outcomes.
