<p>There are various psychologic and environmental factors that affect academic achievement during adolescence. The current research examines how lifestyle attributes, academic pressure, psychological wellbeing and academic performance correlate in adolescents. Stratified random sampling was used to pick up 500 Class X students of the secondary schools in West Bengal. Lifestyle factors, academic stress, and psychological well-being were measured using standardized questionnaires, and academic achievement was measured using the past examination results of students. The SPSS was used to analyze data in terms of descriptive statistics, Pearson correlation and multiple regression analysis. The results indicated that lifestyle and psychological well-being are strongly positively correlated with academic achievement but there is a negative linkage between academic stress and academic achievement. The results of the regression analysis have shown that these variables together can explain a large amount of variance in academic achievement. The findings indicate the need to facilitate healthy lifestyle habits and psychological support programs among school adolescents.</p>
