Starting your first semester in college shouldn't feel like "being thrown in the deep end". You just spent 4 years of high school preparing for it!
But I agree that kids are awfully unprepared for the real world, so maybe coddling kids into early adulthood is unfortunately necessary? The whole situation makes me very sad.
You don't actually have any idea how different high school and college are, do you? Unless the kid went to boarding school, the environmental change is immense.
