Link: Oxford Dictionaries Spelling Challenge



Oxford Dictionaries Spelling Challenge has three levels of difficulty: Tricky, Difficult, Fiendish. Each level will ask 15 questions.

The words you are to be tested on are read aloud [so you will need audio for this] Once the test is complete it will show a summary of your test stating how many were correct out of 15 and give the correct spellings where they were input incorrectly.
