studying donkey

A person who studies a lot, and he gets straight As in tests or exams, but he has no idea what the hell is he doing! A 21st century typical student who only focuses on grades or degrees, and he cares little to zero about the material he is learning, or the outcome of his studies in terms of knowledge and real life applications. Someone who is in school with the main focus of making more money or following the crowd and listening to what others told him, so he tries to do well just to embarrass them. The good student with no qualifications who sums up our educational systems today.

This engineer I work with must have been a studying donkey! He has a PHD, but he cannot answer a single question I ask him at my job.
