The study aimed to investigate the Effect of Academic Stress on Students' Academic Achievements and Its Implications for Their Future Lives. A correlational research design was employed through stratified random sampling (n[subscript i] = 270, where female = 80 and male =190) to collect pertinent data through a questionnaire. Descriptive and inferential statistics were employed. Firstly, academic stress highly affects students' academic achievement, with females being more stressed (65.20%) than males (59.60%), which leads to a high dropout rate and low graduation rate. Secondly, about 69% were accustomed to drinking alcohol, chewing Khat, absenteeism, and smoking whereas about 31% were regularly engaging in unsafe sex, physical fights, smoking shisha, and poor personal sanitation. Thirdly, there were significant positive relationships among sex, age, academic batch, and student's cumulative grade point average. To conclude, academic stress hinders good academic achievement, increases college dropout rates, low graduation rates, and lack of self-confidence. It leads to drinking alcohol, absenteeism, chewing khat, reduced academic morale of students, and failure in completing assignments on time. Therefore, university authorities should ensure a good academic environment for the students and minimize academic stress through appropriate course load, appropriate lecture hours, proper lecture schedules, and non-congested lecture halls.
