Why does school suck?

Most of students have this thought at least once a day. Even though school gave us education and trained some daily skills, schools usually drove students crazy. For instance, different majors teachers might set the homework due or exam date on the same day and principles or teachers would make some unreasonable rules to ask students to follow it. Thus, students had to work really hard on their assighments and being cautious in the school. If we did nnot pay attnetion on those stuff, we would not only failed the class but alos got detension form school. this slogan challenges our culture because most of people only focus on schooling is the mainly way to get better fuuter but does someone thinks about the unfair issues for student in school?
