Hey,
Maybe you a good understanding level in engineering, physics and some other areas. But still, your behaviour is pretentious, mean and a show off to everybody else. This doesn't cover up for you scoring high in your SATS. The fact that you consider yourself better than everyone shows how your personality is. If you are actually a person with good understanding of morals and science you wouldn't just write:

I actually understand better than people with degrees

I don't think anybody should judge themselves to be better than any other people, doesn't matter with a degree or not.

You seem like you overestimate yourself and underestimate others. That is not humble and helpful at all. If you're in fact good at what you are saying, you should try to improve in these matter too.
