I think the main issue with school is that it isn't flexible enough. I get everyone learns at their own pace but having a set schedule just feels WRONG. If a kid is a prodigy and can get all the day's work done in 2 hours, why make them stay for 7 hours, or if a kid is a slow learner and needs more than 10 hours to get their work done, then making them stay for ONLY 7 hours isn't enough time.
