Learning is an instinctual process, but effective learning strategies have to become habitual.
Many people have a problem with mastering math and science, although in most cases language is not a significant barrier. Math uses the language of numbers, which is universal, while science typically uses terms that are not native to any modern society. Yet some people do very well in both fields without even being particularly good in school. Famous figures in science and math that flunked school are Albert Einstein, Michael Faraday, and more recently, Jack Horner.
