First of, totally normal. I think I did worse than you on my first play through. Just guessing, but it’s not necessarily that you were wrong for grinding social stats—-that’s necessary—-but probably that you used not the best activities to do so. Because of the game’s setting, characters are constantly reminding you to study, but in general (unless it’s raining or something) that’s one of the worse ways to raise knowledge. Some activities raise multiple things at once—-did you do the Big Burger challenge? Did you do it often? I spent waaaay too much time studying and reading during “free” times, and that’s a slower growth. So my Joker was sitting with that paper bag of Iwai’s for almost half a year.
