This study examined the influence of test Anxiety on performance Levels on numerical tasks of secondary school Physics students. One hundred and eighty-three SS 3 students (105 males and 78 females) with average age of 15.6 years, SD = 1.68, randomly selected from four co-educational secondary schools in Ibadan North Local Government area of Oyo-State constituted the sample for the study. A questionnaire and two Physics Achievement tests were used for data collection. Findings revealed that the performance levels of low test-anxious students was higher than that of high test-anxious students on both numerical non-numerical Physics tasks. Also, female students were found to be more test-anxious than male students but this difference was not significant.
