Let me warn you about a mistake I’ve often seen in homework from my students. They write sentences like these: I’m going to U.S.A. next year. We visited United States. My friend is from U.S. Can you find the mistake? Click here, or listen for the answer... I’ve got an entire course to help you identify and avoid mistakes like these – it’s the 200 Common Errors in English Course. The lessons cover not only grammar mistakes, but also mistakes in spelling, vocabulary, pronunciation, and even common mistakes and problems in your English learning strategy. I'd love to help you find and fix your English errors fast!
