Oh well I pissed about in school and enjoyed it and i'm still the cleverest person I know. I guess you just have to be there, no matter how seriously you take it
I dont mean to sound wierd but school is actually fun, you meet great people and if you do revision you get rewarded in exams and then this opens a lot of doors for you in later life, if you don't try at school you will suffer the consequences later
Secondary school is 5 years, college 2, university 4, 11 years + 7 for primary thats 18 years out of about 80 you will be alive for, fail the first quarter you have to live the other 3 quarters badly
