how to have better understanding in class???

I've done some research on how sit place affects your understanding skills in class especially to the class which has a letter-u arrangements like what university mostly have. The fact says that people who sits on the right side will have better understanding and listening skills than what people have on the left side. This is related to the ears that we have. Right ear will do better on listening people speak meanwhile the left ear will do better on listening some note of music. Based on what we know previously, right brain is specialized for art things and creativity and left brain is specialized for something related to math. And in human, left brain controls right side of human meanwhile right brain controls left side of human.
People who sits on the right side of the class, of course will use their right ear a lot more than people who sits on the left side. This means that people who sits on the right side of the class will catch what teachers or lecturers explained better as they can catch more on what teachers and lecturers talking about.
My suggestion.... try to sit on the right side of the class for better skill of understanding and listening.
