Would you go to a 50-year-old with a high-school diploma and tell them they only have high-school level thinking? Of course not. Colleges do not have a monopoly on your ability to learn. Many people read a lot of books, for instance, without a teacher telling them to. Meanwhile, there are plenty of ways to get through college without getting past a high-school level of thinking.
