I think thats just how it works. If you found school harder then you probably developed some skill or habit knowingly or otherwise, but if you found it easy then you just never did put in effort to develop such skill. Of course this does not apply to all.
Same here for me. Learning in school never took any effort at all. I was always good enough with little practice that I didn’t push myself to do more.
College is the great equalizer that shows people they’re not as gifted as they thought.
Ironically I found school easily 10x harder than anything at university, bachelors and masters level included.
