Petals Around the Rose: Fraternity Register

hey i was just wondering what was the purpose of the puzzle cause it confused me when in the intro it said that the longer u take to solve the smarter u are well it toke me second try to get it does that mean i'm not smart i can accept that but i dont get it usually only smart ppl can solve puzzle or maybe i just got a creative way of thinking maybe its not about hom smart u are but how creative u are combine with maths as well. well thats all i have to say
