The purpose of this quantitative study was to provide statistical evidence to support that if males take the Caribbean Certificate of Secondary Level Competence (CCSLC) mathematics examination before the Caribbean Secondary Education Certificate (CSEC) mathematics examination, they will have a statistically significantly higher average score than those who only take the CSEC mathematics examination. In addition, the study also proposed statistical evidence to support that if males take the CCSLC mathematics examination before the CSEC mathematics examination, there is a statistically insignificant difference between the average female and average male scores on the CSEC mathematics examination for those between 14 and 19 years old. With respect to research question one, the results indicated that male students who wrote the CCSLC mathematics examination before the CSEC mathematics examination received a statistically significantly higher mean score than their male counterparts who only took the CSEC mathematics examination. With respect to research question two, when compared to female students who wrote the CCSLC mathematics examination before taking the CSEC mathematics examination, the results indicated that the male students who wrote the CCSLC mathematics examination before the CSEC mathematics examination mean score was marginally higher than the female student. Although the male students' score was marginally higher than the female student, based on the two-sampled independent t-test, there was no statistically significant difference in mean scores.
