// Need to countdown as well as storing the countdown length ready to shorten after the right number of questions.

// Page loads -> question is displayed -> countdown begins 
// -> if countdown ends -> page reloads with "incorrect"
// -> if answer is posted -> answer is checked 
// -> if answer is correct -> new question is loaded & countdown length is checked
// -> if countdown length needs to change it is changed
// -> if answer is incorrect -> page reloads with "incorrect"
