This study aimed to determine the significant effect of the Stress Coping Strategy and Test Taking Strategy on the Perceived level of Mathematical Skills of students in Mathematics in the Modern World at Agusan del Sur State College of Agriculture and Technology (ASSCAT). There was a total of 169 respondents, which were comprised of BSEd-Mathematics, BSEd-Science, BSEd-English, and BEEd students, which were identified through a proportional stratified random sampling technique. The researchers utilized various data gathering tools, including questionnaires from the studies of Oliva, Ricablanca, Bacus, and Moneva (2019) for Coping Strategy, Bicak (2013) for Test Taking Strategy, and Cornillez, Jordan, and Yocte (2020) for the Perceived level of Mathematical Skills in MMW. The statistical tools used were mean, Pearson Product-Moment Correlation, and Multiple Regression analysis. The result of the study showed that the level of coping strategy and test-taking strategy were all described as high, and the level of mathematical skills was described as good. Furthermore, the result revealed that there was a strong positive relationship between the coping strategy and the test-taking strategy, which correlates to the level of mathematical skills of students in MMW. In addition, it was found that the Coping Strategy and Test Taking Strategy can significantly affect the level of Mathematical Skills of Students and can be summarized by a model Y= 0.500X1 + 0.357X2.
