The purpose of the present study is investigating quantitative and qualitative factors influencing students’ Mathematics performance at a particular College situated in Oman. It examined the correlation between attendance percentage, prior Mathematics learning, communication skills, mode of study, & gender, and students’ Mathematics performance using relevant data from the College’s database, year 2021 – 2022. Moreover, survey reports were also used to identify other factors. Analysis of the data used product-moment correlations, biserial correlation along with ANOVA, and thematic method. Gender and mode of study did not emerge as part of the equation; however, the findings indicated that English communication skills, class attendance, and prior Mathematics scores have significant effects on students’ overall Mathematics performance. Furthermore, the thematic analysis found that although students are satisfied with the school climate, it seemed to suggest that students were burdened with the topics and were lacking proper motivation due to issues on teaching styles and lack of exercises linked to real-life applications.
