You can take the course exam as many times as you wish, at no extra cost, but the Florida State Law requires you to wait 30 days until you can take it again. The good news is that you don't have to take it unless you are ready. As soon as you pass all the quizzes, you will see the 100-question Practice exam, and will be able to take it as many times as you wish, until you feel confident. You can also take the quizzes at the end of each chapter as many times as you wish. Passing or failing them will not have any consequences. As you will see, the end of course quizzes have 10 questions, but they show up randomly. It gives you 10 random questions out of about 50. This means that when you retake the quiz, it will never be the same. Same with the 100-question practice and final exam. We suggest taking each quiz multiple times until you score 100 on each one of them. Only then take the long 100-question practice exam. Take the final course exam only when you are absolutely sure that you will pass, so that you don't have to wait 30 days until you can take it again. After you pass the final exam, don't waste any time and take the Florida state exam as soon as possible before you start forgetting  information you learned.
