I'm a professor at a top Ivy, so I see a lot of those kids. Generally, they're all wasting their time -- they could spend half as much time and the quality of their work would drop 1%. Efficiency matters. At some point I'll figure out how to convince them of this fact, and I will have succeeded as an educator.Even the grades don’t account for anything , but my dd always has strong work ethic or making sure all assignments perfect , making grades perfect... This type of kids easily get exhausted.
