Advising is one of those situations where everyone thinks it’s easy, until it’s not. Both my kids had special circumstances. My daughter was a double major and how certain classes were counted toward both majors and general education requirements required input and in a few circumstances petitions. My son had a serious medical issue at the beginning of sophomore year that resulted in assistance from his regular advisor, disability services and transportation who all coordinated when he missed the first week of school. Then he switched majors and needed some of his intro engineering classes for one engineering major to be applied to another.
It’s also true that the kids who need advising the most - typically first generation, low income students without good family support that are most harmed.
