How can you improve your spelling?

The best thing you can do to improve your spelling is to read a lot and look up words that you don’t know in the Oxford dictionary

Learn as many words as you can.
Study the most common words first.
Focus on the words that are tough.
Write the words somewhere. Just writing the words will help you remember them
Get a copy of the OXFORD Dictionary if you can. It’s the official dictionary for the Kenya National Spelling Bee Championship.
Have a teacher, friend or family member help you by pronouncing the words.
Learn more about prefixes, suffixes and other combining forms, as well as word origins (etymology).
Increase your vocabulary by reading books, journals & newspapers…
Study in groups.
Play word games.
Step forward (to the microphone, if there is one).
Face the judges.
Speak clearly and loudly enough so that they can hear you.
Use the English alphabet only.
Many languages use the Roman alphabet. Do not use the names or sounds of the letters in French or any other language. Doing so will be considered an error.
Repeat the word to make sure that you have heard it accurately.
Rehearse the word in your mind before you begin spelling.
Once you say a letter you are not allowed to take it back, even if you have not finished the word and know it is wrong.
When you’ve finished spelling the word, repeat it. That way the judges know you are finished.
Take your time.
Asking questions is a good stalling tactic if you need more time to think about the spelling.
If you spell your word correctly, be humble about it.
