Increasing IQ

Hello, I need help!
I am trying to increase my IQ to get a job as a particle physicist, need to raise it to 85 % I am trying everything possible but the maximum I could reach is 82% and after that it falls. I play chess, sudoku, read books that increase IQ, hang out with friends who helps reasoning… what else I could do? Is there something I am missing? Anyone knows?

thanks in advance

Are you increasing all four stats that make up IQ?

Problem Solving, Knowledge (IQ), Logic and Reasoning. You need to increase all four stats to get to 100%.

Ah yes I noticed I was missing knowledge… thank you for the help!
