My experience seems to resonate with a good amount of ppl here. I graduated from a very average university and my grades were a roller-coaster, I tend to prefer learning in depth topics that I'm interested into rather than study for exam and that led me to difficult times. I went to a more prestigious university for exchange and to my surprise students were not better in in-depth understanding but even more exam-smart...

One thing I've ended thinking is that University is just not good for learning in-depth (at least my field of computer engineering) I'm way better at that on my own, what it was good at tho is helping me building a map of knowledge of concepts I was not aware of, I'm thankful I discovered ML in a class which then became my passion and career.
