Memory test with time check

This exercise is an unusual game based on the use of memory; you have to memorize 15 different words and, after that, you have to answer 15 questions asking for each word you memorized. It's not all, in fact the test does not only consist in memorizing and answering, it also takes your time! You have to complete the exercise in the minimum possible time. Each mistake you make will cause the test to restart from the first question, and only after giving all 15 correct answers in a row your time will be stopped. Good luck!
