WHY STUDENTS FAIL?!?!?!?!

Actually, It's not students' faults if they'd been becoming so. However, all of you know that the Years only has 365 days?

So here is the short typical academic for a student:-
● We got 52 days of Sundays, it's the day where all of humanity got right to rest their minds.Days left: 313
● When Summer vacation, we got about 50 days holiday, but we knew already that the hot weather (especially at Mideastern) give a lot of difficulty to study. Days left: 263
● We'll need 8 hours for daily sleep. In a short words, 130 day's gone! Days left: 141
● 1 hour of daily playing (I mean it also for outdoor activities, everybody knew that it's good for health) , it might take 15 days. Days left: 126
● For food and other delicacies, it would take 2 hours daily (Chewing properly & swallowing). Means 30 days. Days left: 96
● An hour for talking (society means for goodness). It's about 15 days. Day's left: 81
● Examinations Day! On a year, at least 35 days taken. Day's left: 46
● Some events of a year or even festival (It may said as holiday too). Counted to be 40 day's for that. Day's left: 6
● For sickness, at least 3 days enough already (Here we just took Fever for average of the sickness). Days left: 3
● Movies and functions. 2 days gone. Days left: 1
● At last, your birthday!! Day's left: 0

Balance of all of those average: 0 (Zero!!!)
How could we study with that?? It's such a usual things if we're FAIL!!!!!!
