Quizzes are setup to allow you to take them multiple times. When you view a quiz it will show you how many times you have left to take it.
To take a quiz, simply view the quiz you would like to take and click the Take Quiz button if it is available.
Maximum Limit
Some quizzes might have a maximum amount of tries. If you reach that amount you will not be allowed to take the quiz again and will see the following text:
Prerequisites
Some quizzes might have a prerequisite quiz defined. This means that you have to pass the prerequisite quiz with a certain score before you will be allowed to take this quiz.

If you take a quiz that requires approval before you complete it you will be prompted with a message that the quiz entry needs to be approved. Once it is approved you will be sent a notification that you may continue with the quiz.

Once you are taking the quiz you may be presented with types of quiz options. Once you have reached the end of the quiz you will be presented with the option to review your choices.
You will have the chance to go back and edit your answers at this time.
When you believe your answers are correct select the Mark Completed button to finish the quiz.
If the quiz requires manual scoring (Essay or Short Answer) your quiz will not receive a score at this time. It will be scored later.
If your quiz does not require manual scoring you will be presented with your scored (or result generated) quiz.
Question Types
Multiple Choice/Multiple Selection
I believe these type of questions are familiar to anyone who has ever been to school. I don't think I need to explain their operation.
Double Ended
Double Ended questions can also be used for a short 1 or 2 word answer question. The object of a double ended question is to use two sentences where the answers share a common word to create a statement.
Ex.
Ridley Scott directed film with Cage & Rockwell.
Matchstick Men in Black Comedy about aliens starring Tommy Lee Jones and Will Smith.
Essay/Short Answer
Essay and short answer questions need to be scored by a person manually and cannot be added to a Variety Quiz. They can have a fixed character length as defined in the ACP
Matching
Matching questions will have a list of questions on the left and their jumbled up answers on the right. Enter the letter from the right side into the box on the left side.
Result Generator/Advanced Result Generator/Personality by Decado
These type of quizzes will ask you a series of multiple choice questions to generate a result based on your answers.
