Based of the book by Jim Winchester. Any problems or otherwise, please leave a comment. This was my first quiz, so far my most popular quiz. Thank you.
There is a misspelling on the displayed 'Z' answer. Also it would be good to accept a few alternative spellings as some of the answers are quite tricky, e.g 'F', 'I', M' and 'T'.
I made some adjustments to the quiz. I added alternative spellings to try and make the quiz easier based on the percentage of those who took and their answers.
