There are six programs within Hot Potatoes - JQuiz for quizzes, JCloze for gap-fill exercises, JCross for crosswords, JMix for reordering sentences, JMatch for matching questions, and The Masher to combine different exercise types into one integrated unit. Teachers can input questions, answers, and feedback and Hot Potatoes will generate the necessary web pages without requiring knowledge of HTML or web design.
