This study explored mathematics anxiety and mathematics self-efficacy of senior high school students in Botolan District of Zambales during the academic year 2020-2021. The students are female, belong to young adults, and are Grade 11 senior high school students. Descriptive research was employed in the study, using ANOVA, T-test, and Pearson r to test the significant difference and relationship of variables. Findings revealed that there is a high positive level of Mathematics anxiety and Mathematics self-efficacy of the students. Students stated that learning Mathematics made them feel nervous. Students acknowledged that Mathematics is a complex and difficult subject, and they lack mathematical skills to solve complex problems. For Mathematics anxiety, students' perceptions according to age do not differ significantly. When attributed to sex, perceptions differ significantly on the Face Expression, while perceptions on the Appraisal, Arousal, and Action Tendencies are the same. In terms of the strand, perceptions differ significantly on the Arousal and Face Expression. In terms of school, the significant difference only matters on the Action Tendencies. For Mathematics self-efficacy, perceptions according to age on the Mastery Experience, Vicarious Learning, and Affective State aspect of Mathematics self-efficacy differ significantly, while perceptions on Social Persuasion are the same. When grouped according to sex, perceptions on Vicarious Learning and Affective states differ significantly. In terms of school, perceptions only differ significantly on Physiological State. Moreover, the perceived level of Mathematics anxiety and Mathematics self-efficacy differ significantly. The paper also concludes that Mathematics anxiety and mathematics self-efficacy influence students' academic performance. A follow-up study may be conducted on the difference in age, school and Mathematics self-efficacy to validate the result of the findings.
