Summary: A game that will test your reaction time based on how fast you enter the corresponding letter that appears on screen
Part I: the basics When you start a game, the program shows you a random letter from the alphabet There is a textbox for you to type in the correct phonetic word for that letter, and press enter. if you get it right it goes hooray!and takes you to a new letter if you get it wrong it quickly shows you the correct answer before moving to a new letter when a round is complete it shows your score (you can decide the length of a round).
Part II: test for speed You're not truly trained in the phonetic alphabet until you have instantaneous recall. So don't count an answer correct unless the user types in the correct answer quickly enough. I think I set mine to something like 2-3 seconds or something like that.
