[[Scratch]] contains the resources available for creating a question/answer system. This system can be used for one to be "quizzed", or to repetitively answer automated questions. This tutorial shows various methods on how to create a question system. For each method, the [[Ask () and Wait|ask () and wait]] block is used to ask questions and input answers.

==Simple Method==
This method can become lengthy in scripting, repetitive, and orderly, but still accomplishes a simple question system. The script tells the sprite to ask a question, detect if it is right or wrong, and play a sound according to the outcome. This is a simple way to program a quiz game.
<scratchblocks>
when gf clicked
ask [What is 1+1?] and wait
if <(answer) = [2]> then
play sound [correct! v] until done
change [correct v] by (1)
else
play sound [wrong v] until done
end
. . . //repeat the above script with different questions for any desired amount of time
</scratchblocks>

==List Method==
The next method continuously picks a random question to ask, with questions and answers added to certain lists. The list storage makes adding questions and answers quicker. Each item in the list "questions" must directly correspond to the same item in "answers". Further methods can be used to group questions and implement other functions for various purposes. For the following tutorial, assume the following:
* "questions" is the [[list]] which contains each question
* "answers" is the list which contains the corresponding answers to the questions in the list above
* "item#" is a [[variable]] used to determine the current question one can answer
<scratchblocks>
when gf clicked
forever
set [item# v] to (pick random (1) to (length of [questions v])) //picks a random question
ask (item (item#) of [questions v]) and wait //asks the question and waits for the response
if <(answer) = (item (item#) of [answers v])> then//if the answer is correct
play sound [correct! v] until done//notifies the viewer that the answer is correct
else
play sound [wrong v] until done//notifies the viewer that the answer is incorrect
say (item (item#) of [answers v]) for (1) secs //used to display what the correct answer was
</scratchblocks>

==Group Method==
This method is much like the List Method of coding a quiz, but the Grouping Method can be used to group questions and repetitively ask the specified group of questions until a condition is reached. For example, if there are twenty questions, this method can be used to ask four of those questions in the group until they are known very well, and then the system will select a new group. For this method, assume the additional following:
* "current questions" is the list which contains the current group of questions
* "current answers" is the list which contains the current group of corresponding answers
* "correct" is the variable used to determine how many questions of a specific group have been correct
<scratchblocks>
when gf clicked
forever
delete (all v) of [current questions v] //clears the current group's questions
delete (all v) of [current answers v] //clears the current group's answers
set [correct v] to (0) //resets the amount if correct answers for the new group
repeat ([ceiling v] of ((length of [questions v]) / (5))) //each group contains 1/5 of the total questions
set [item# v] to (pick random (1) to (length of [questions v]))
add (item (item#) of [questions v]) to [current questions v] //adds a questions to a group
add (item (item#) of [answers v]) to [current answers v] //adds the corresponding answer
end
repeat until <(correct) = [15]> //"15" can be changed to the desired amount needed correct each group
set [item# v] to (pick random (1) to (length of [current questions v])) //picks a random question
ask (item (item#) of [current questions v]) and wait //asks the question and waits for the response
if <(answer) = (item (item#) of [current answers v])> then//if the answer is correct
play sound [correct! v] until done //notifies the viewer that the answer is correct
change [correct v] by (1)
else
play sound [wrong v] until done //notifies the viewer that the answer is incorrect
say (item (item#) of [current answers v]) for (1) secs //used to display what the correct answer was
</scratchblocks>

==Mathematical Method==
This method is used in a math quiz in a way very much like the list method, but takes use of the [[Operators Blocks|Operators blocks]] to make several possibilities without needing to list them.
Take, for example, randomly generated addition questions involving addends from 1 to 20. For this method, assume these variables:
* "number1" is the first added to the question
* "number2" is the second added in the question
* "expect_answer" is the expected answer of the generated question
<scratchblocks>
when gf clicked
hide variable [expect_answer v] // hides the answer
forever
set [number1 v] to (pick random (1) to (20))
set [number2 v] to (pick random (1) to (20)) // generates two random integers from 1 to 20
set [expect_answer v] to ((number1) + (number2)) // calculates the result
ask (join (number1) (join [ + ] (number2))) and wait // asks the question
if <(answer) = (expect_answer)> then // if the answer is correct
play sound [correct v] until done// notifies the viewer that the answer is correct
else // if the answer isn't correct
play sound [wrong v] // notifies the viewer that the answer is incorrect
show variable [expect_answer v] // tells viewer what the correct answer was
wait (4) secs // assures that the viewer has enough time to react before the variable is hidden again
hide variable [expect_answer v] // hides the variable in preperation for the next loop
end
end
</scratchblocks>
