+Study time, mental health, and exercise show positive influence on exam scores.  
+Netflix hours and heavy social media use show negative or weak negative effects.  
+Lifestyle factors such as attendance, diet, and internet quality matter less than expected.
+
+Students who balance healthy routines — good study habits, sleep, mental well-being, and moderate screen time — tend to perform better academically.
