This study was an ex-post-facto survey, which investigated students’ mathematics and English language (mock) achievement as predictors to school certificate performance in Physics, using two hundred and fifty (250) students randomly selected from public secondary schools in Rivers State. The data was analyzed using the Pearson Product Moment Correlation Coefficient and t-test inferential statistics. In order to predict the performance of students on physics based on their performances in Mock examinations on mathematics and English language, the multiple regression analysis (R2) was used. Results showed that there was a significant relationship between the performance of students in English language Mock examination and their performance in physics. There was also a significant relationship between students’ performance in mathematics mock examination and their performance in physics (SSCE). Although there exist positive dependence of performance of physics (SSCE) on their collective performances in. mock examinations on mathematics and English language, the predictor variable Y1=38. 79 EM+0.17Mm where the partial multiple regression coefficients are 38.79 and 0.17 respectively. Based on these findings, it was recommended that learners of physics should be involved in acquisition of knowledge in mathematics and English language, if their performance in physics should improve.
