Why student fails in exam?????

It's not the fault of the student if he/she fails, because the year has an ‘ONLY 365’ days.
Typical academic year for a student1. Sundays - 52, Sundays in a year, which are rest days. Balance 313 days.2. Summer holidays - 50, where weather is very hot and difficult to study. Balance 263 days.3. 8 hours daily sleep - means 122 days. Balance 141days.4. 1 hour for daily playing - (good for health) means 15 days. Balance 126 days.5. 2 hours daily for food & other delicacies (chew properly & eat) - means 30 days. Balance 96 days.6. 1 hour for talking (man is a social animal) - means 15 days . Balance 81 days.7. Exam days per year atleast 35 days. Balance 46 days.8. Quarterly, Half yearly and festival holidays - 40 days. Balance 6 days.9. For sickness atleast 3 days. Balance 3 days.10. Movies and functions atleast 2 days. Balance 1day.
