I haven't taken any "real"(professional like Mensa) testing but I usually score between the high 130's to 150.
The only thing I can think of in regards to thinking is well it never stops.
Yes I'd say I'm natural problem solver. I would say that I'm highly visual at times and really have a photographic memory. I just see things in the quickest route being worked out. It helps to be open minded to other ways of doing things.
Sometimes there is much easier ways of doing things that people don't think of, or if they do they lack faith they can DO it. In my opinion there is no such thing as ONE way, or one right way, there are many ways to do things and all can be right.
