>>11549686Had a similar thing but I'm a few years older than you. I had Cs in my first semesters and a lot of stuff seemed confusing and I couldn't grasp them. I mostly spent my time playing dark souls, CSGO or just doing whatever. I also had about C- in highschool except in STEM classes. 2 years passed or so and looking back at the work I previously did looks like a child did it. Now my lowest grades are in the B+ if I dont put any effort whatsoever despite being harder classes.
It kind of feels like a spike in thinking and memory to me, but it's more like some kind of clarity. Stuff that used to be confusing or unintuitive to me only a few months back is now stupid simple and easy to understand.
Cant answer your question though. I have no clue why this happened since I thought at the age of 19-22 or so your brain was sufficiently developed that there would not be any notable changes. Might also just all be in my head, but the grades and transcripts dont lie.
Maybe I'm also just overthinking it and it's normal for people in this age range to see their average grade per semester increase by more than 15% for no reason.
