Why students fail exams

I got sent this in an e-mail this week - i always knew it wasn't my fault!

It's not the fault of the student if they fail, because the year ONLY has 365' days. Typical academic year for a student:
1. 52 Sundays in a year, you know Sundays are for rest. Days left 313.
2. Summer holidays-50 where weather is very hot and difficult to study. Days left 263.
3. 8 hours daily sleep- 130 days GONE.. Days left 141.
4. 1 hour for daily playing- (good for health) means 15 days. Days left 126.
5. 2 hours daily for food & other delicacies (chewing properly & swallowing)-means 30 days. Days left 96.
6. 1 hour daily for talking (man is a social animal)-means 15 days, days left 81.
7. Exam days- per year at least 35 days. Days left 46.
8. Quarterly, Half yearly and festival (holidays)-40 days. Balance 6 days.
9. For sickness- at least 3 days. Remaining days=3.
10. Movies and functions- at least 2 days. 1 day left.
11. That 1 day is your birthday. How can you study on that day???
Balance = 0
