Speed review is a fun and fast way to review items. Select the red timer icon on the course you would like to review.
Speed Review will test you on all the words you have learnt so far in this specific course, so essentially not only the ones that need reviewing. The main difference between Classic Review and Speed Review is the timer function within the Speed Review. The user will have a certain amount of seconds to input their answers per question. If the time runs out the user will lose a heart, which is displayed at the top of the screen. There are three hearts per session.
