In my opinion, any time you try to group everyone together and give them all the same expectations and things to learn there are people not being challenged to their potential and those who are struggling to get by. As a child were you ever told that 'everyone is different', 'everyone is special in their own way', ect.? We should take this truth and apply it to our education system, In order to have every student reach their full potential, we should break it down and organize it on an individual level, without blanket expectations and curriculums.
