20 Most Common Spelling Errors

Pick a few words to learn at a time. When you find a useful or interesting word while reading, in conversation, or in class, write it down. Every day, write down each word on your list three times and spell it out loud. Literally one minute of this "studying" each day will teach you the spelling quite quickly. Remove words from the list once you're confident you know the spelling. Add new words to replace them.
