How does a person with an IQ of 250 acquire knowledge and learn?

I think I understand what you are asking, though I’m not sure what 250 IQ even means. The more intelligent a person is, the easier it is for that person to make connections with past things they have learned and this builds on itself very young and very fast when given the resources. I saw one post about a GOOD OL’ BOY FROM GEORGIA and I envy him in a way, I love fishing too, but I also loved learning and have always had an incredible hunger for learning and expanding my understanding of this existence. To answer the question, it is far easier for an intelligent person to pick up a text book, read through it and retain it, than it is for someone with less intelligence. However, with hard work and commitment to improving yourself, you will be surprised at what you can accomplish, no matter what your intelligence is.
