They are similar, but there is a small difference. "Schooling" means going to school or university, taking classes, and graduating. "Education" means learning new information and skills, and becoming a more knowledgeable person. For example, reading a book or learning a language on your own could be part of your education (or could be "educational"), but not part of your schooling. There is a famous quote about this sometimes attributed to the great American writer Mark Twain: "I have never let my schooling interfere with my education." Now that you know the difference between these two words, can you tell what he meant?

There is no significant difference. Although, there is a slang use of "schooling" that is slightly different. If two people compete and one is shown to have far better skills, they say that the other person "got schooled".
