Section C Predictions edit
The 2022 paper 1 will contain 5 questions worth 17 marks. As long as you know the program well, this will be a walk in the park.
06. This question is about the Breakthrough class.
06.1 State the name of a Boolean attribute in the Breakthrough class. [1 mark]
06.2 State the name of a method in the Breakthrough class that uses exception handling. [1 mark]
06.3 With reference to the CreateStandardDeck and AddDifficultyCardsToDeck methods and the "game1.txt" file - how many cards in total are in the deck? [1 mark]
06.4 With reference to the "game1.txt" saved game file, state what each line of the saved game file represents. [2 marks]
07. This question is about the method __Loadlocks in the Breakthrough class.
07.1 State the datatype used for __Locks. [1 mark]
07.2 State a correctly formatted single line which could be added to the "locks.txt" file to represent a 3-challenge lock needing an Acute Pick, Basic File and a Crude Key to open it. [1 mark]
08. This question is about the CreateStandardDeck and AddDifficultyCardsToDeck methods in the Breakthrough class.
08.1 State the type of iteration used. [1 mark]
08.2 State how many difficulty cards are generated when the game is run.
08.3 State how many other cards are generated when the game is run.
08.4 If we wished to make the game less difficult (reducing the number of difficulty cards from five to three), describe the necessary code changes which would need to be made assuming we wanted to keep the overall total number of cards the same.
- Question about a class?
- Question about a second class?
- Question about a third class?
- Question about a class diagram?
- Question about a game functionality such as how to tell if game is ended?
- Question about why text files were used over other file types to store data?
These predictions are made based on last year's Advanced Subsidiary paper
Section D Predictions edit
Programming Questions on Skeleton Program
- The 2022 paper 1 contains 4 questions: a 5 mark, a 9 mark question, a 10 mark question and one 13 mark question - these marks include the screen capture(s), so the likely marks for the coding will be 1-2 marks lower.
- The 2021 paper 1 contained ...
- The 2020 paper 1 contained 4 questions: a 6 mark, an 8 mark question, a 11 mark question and one 12 mark question - these marks include the screen capture(s), so the likely marks for the coding will be 1-2 marks lower.
- The 2019 paper 1 contained 4 questions: a 5 mark, an 8 mark question, a 9 mark question and one 13 mark question - these marks include the screen capture(s), so the marks for the coding will be 1-2 marks lower.

Current questions are speculation by contributors to this page.
Fix Key 1-5. edit
Fix "IndexOutOfRange" exception caused by inputting a card number not in the range 1 to 5.
C#:
private int GetCardChoice() {
do {
Console.Write("Enter a number between 1 and 5 to specify card to use:> ");
Choice = Console.ReadLine();
loop = !int.TryParse(Choice, out Value);
if (Value > 0 && Value < 6) {
inRange = true;
}
else {
inRange = false;
}
} while (!inRange || loop)
return Value;
}
Delphi/Pascal:
Java:
private int getCardChoice() {
String choice;
int value = 0;
boolean parsed;
do {
Console.write("Enter a number between 1 and 5 to specify card to use:> ");
choice = Console.readLine();
try {
value = Integer.parseInt(choice);
parsed = true;
} catch (NumberFormatException e) {
parsed = false;
}
} while (!parsed || value < 1 || value > 5);
return value;
}
Python:
This handles characters and out of range integers entered.
def __GetCardChoice(self):
Choice = 0
while not 0 < Choice < 6:
try:
Choice = int(input("Enter a number between 1 and 5 to specify card to use:> "))
except:
pass
return Choice
VB.NET:
Private Function GetCardChoice() As Integer
Dim Choice As Integer = 0
Dim Value As Integer
While Choice < 1 Or Choice > 5
Try
Do
Console.Write("Enter a number between 1 and 5 to specify card to use:> ")
Choice = Console.ReadLine()
Loop Until Integer.TryParse(Choice, Value)
Catch ex As Exception
End Try
End While
Return Value
End Function
Private Function GetCardChoice() As Integer
Dim Choice As String
Dim Value As Integer
Do
Console.Write("Enter a number between 1 and 5 to specify card to use:> ")
Choice = Console.ReadLine()
Loop Until Integer.TryParse(Choice, Value) And (Value > 0 And Value < 6)
Return Value
End Function
Add Load Function edit
Add functionality to select (load) a specific (saved) game file (currently no choice is given).
C#:
private void SetupGame()
{
string Choice;
Console.Write("Enter L to load a game from a file, anything else to play a new game:> ");
Choice = Console.ReadLine().ToUpper();
if (Choice == "L")
{
//Loading
Console.WriteLine("Please Enter the filename");
string filename = Console.ReadLine();
if (!LoadGame(filename + ".txt"))
{
GameOver = true;
}
//Loading
}
else
{
CreateStandardDeck();
Deck.Shuffle();
for (int Count = 1; Count <= 5; Count++)
{
MoveCard(Deck, Hand, Deck.GetCardNumberAt(0));
}
AddDifficultyCardsToDeck();
Deck.Shuffle();
CurrentLock = GetRandomLock();
}
}
Delphi/Pascal:
Java:
private void setupGame() {
String choice;
Console.write("Enter L to load a game from a file, anything else to play a new game:> ");
choice = Console.readLine().toUpperCase();
if (choice.equals("L")) {
Console.write("Enter file to load:> ");
String name = Console.readLine();
if (!loadGame(name)) {
gameOver = true;
}
} else {
createStandardDeck();
deck.shuffle();
for (int count = 1; count <= 5; count++) {
moveCard(deck, hand, deck.getCardNumberAt(0));
}
addDifficultyCardsToDeck();
deck.shuffle();
currentLock = getRandomLock();
}
}
Python:
def __SetupGame(self):
Choice = input("Enter L to load a game from a file, anything else to play a new game:> ").upper()
if Choice == "L":
if not self.__LoadGame( input("Enter file to load:> ")):
self.__GameOver = True
else:
self.__CreateStandardDeck()
self.__Deck.Shuffle()
for Count in range(5):
self.__MoveCard(self.__Deck, self.__Hand, self.__Deck.GetCardNumberAt(0))
self.__AddDifficultyCardsToDeck()
self.__Deck.Shuffle()
self.__CurrentLock = self.__GetRandomLock()
VB.NET:
Private Sub SetupGame()
Dim Choice As String
Console.Write("Enter L to load a game from a file, anything else to play a new game:> ")
Choice = Console.ReadLine().ToUpper()
If Choice = "L" Then
Dim file As String
Console.WriteLine("Enter File to load")

If Not LoadGame(file) Then
GameOver = True
End If

Next
AddDifficultyCardsToDeck()
Deck.Shuffle()
CurrentLock = GetRandomLock()
End If
End Sub
Require player to complete challenges in order edit
Currently the challenges for a lock do not need to be completed in order. Change the functionality to only allow the user to complete challenges for a lock in the order they are listed.
C#:
public virtual bool CheckIfConditionMet(string sequence)
{
foreach (var C in Challenges)
{
if (!C.GetMet() && sequence == ConvertConditionToString(C.GetCondition()))
{
C.SetMet(true);
return true;
}
else if (!C.GetMet() && sequence != ConvertConditionToString(C.GetCondition()))
{
return false;
}
}
return false;
}
Delphi/Pascal:
Java:
public boolean checkIfConditionMet(String sequence) {
for (Challenge c : challenges) {
if (!c.getMet()) {
if (sequence.equals(convertConditionToString(c.getCondition()))) {
c.SetMet(true);
return true;
}
else {
return false;
}
}
}
return false;
}
Python:
def CheckIfConditionMet(self, Sequence):
for C in self._Challenges:
if not C.GetMet():
if Sequence == self.__ConvertConditionToString(C.GetCondition()):
C.SetMet(True)
return True
else:
return False
return False
VB.NET:
Public Overridable Function CheckIfConditionMet(ByVal Sequence As String) As Boolean
For Each C In Challenges
If Not C.GetMet() Then
If Sequence = ConvertConditionToString(C.GetCondition()) Then
C.SetMet(True)
Return True
Else
Return False
End If
End If
Next
Return False
End Function
Difficulty card functionality edit
At the moment a difficulty card will give the user the option to discard 5 cards OR discard a key by selecting it using 1-5. Change the functionality to force the user to select a key to discard OR if no keys are in the players hand then discard 5 cards from the deck.
C#:
if (Hand.GetNumberOfCards() == 0)
{
Console.Write("5 Cards have been discarded from the deck ");
Discard.AddCard(CurrentCard);
CurrentCard.Process(Deck, Discard, Hand, Sequence, CurrentLock, "D", cardChoice);
}

Keys += 1;
}
if (Keys > 0)
{
do
{
newKeys = 0;
do
{
Console.Write("To deal with this you need to select a card to discard ");

Difficulty error edit
When given a difficulty card, the program will ask for either a 1-5 input or discard 5 deck cards. When a Key is selected it will not always discard it because the list index changes itself.
C#:
Delphi/Pascal:
Java:
// Changes to DifficultyCard process method
if (parsed) {
if (choiceAsInteger >= 1 && choiceAsInteger < 5) {
if (hand.getCardDescriptionAt(choiceAsInteger - 1).charAt(0) == 'K') {
Card cardToMove = hand.removeCard(hand.getCardNumberAt(choiceAsInteger - 1));
discard.addCard(cardToMove);
return;
} else {
Console.writeLine("Card selected is not a key, discarding 5 cards from the deck.");
}
} else {
Console.writeLine("Invalid card position, discarding 5 cards from the deck.");
}
}
// Changes made to Breakthrough getCardFromDeck method
Console.write("To deal with this you need to either lose a key ");
Console.write("(enter 1-4 to specify position of key) or (D)iscard five cards from the deck:> ");
String choice = Console.readLine();
Python:
#Changes to GetCardFromDeck

Retrieve card edit
Create a new card child class for a Retrieve card. If a player draws a retrieve card they are able to retrieve one card from the discard pile and return it to their hand. There should be two retrieve cards in the deck. These should be added, like the difficulty cards, after the user draws their hand.
C#:
Delphi/Pascal:
Java:
class RetrieveCard extends Card {
protected String cardType;
public RetrieveCard() {
super();
cardType = "Ret";
}
public RetrieveCard(int cardNo) {
cardType = "Ret";
cardNumber = cardNo;
}
@Override
public String getDescription() {
return cardType;
}
@Override
public void retrieve(CardCollection hand, CardCollection discard) {
Console.writeLine(discard.getCardDisplay());
int choiceAsInt = 0;
do {
Console.writeLine("Choose a card to return to your hand:> ");
String choice = Console.readLine();
try {
choiceAsInt = Integer.parseInt(choice);
} catch (Exception e) {
Console.writeLine("Invalid card position");
Console.writeLine();
}
} while (!(choiceAsInt > 0 && choiceAsInt <= discard.getNumberOfCards()));
hand.addCard(discard.removeCard(discard.getCardNumberAt(choiceAsInt - 1)));
}
}
// In Breakout class
public void addRetrieveCardsToDeck() {
for (int i = 0; i < 2; i++) {
deck.addCard(new RetrieveCard());
}
}
// Changes to getCardFromDeck method
} else if (deck.getCardDescriptionAt(0).equals("Ret")) {
Card currentCard = deck.removeCard(deck.getCardNumberAt(0));
Console.writeLine("Retrieve card found!");
currentCard.retrieve(hand, discard);
}
// Changes to setupGame method
addDifficultyCardsToDeck();
addRetrieveCardsToDeck();
deck.shuffle();
Python:
class RetrieveCard(Card):
def __init__(self):
self._CardType = 'Ret'
super(RetrieveCard, self).__init__()
def GetDescription(self):
return self._CardType
def Process(self, Deck, Discard, Hand, Sequence, CurrentLock, Choice, CardChoice):

elif self.__Deck.GetCardDescriptionAt(0) == 'Ret':
CurrentCard = self.__Deck.RemoveCard(self.__Deck.GetCardNumberAt(0))
print()
print("Retrieve card encountered!")
print(self.__Hand.GetCardDisplay())
print()
print(self.__Discard.GetCardDisplay())
choice = input('Choose a card to retrieve from the Discard pile')
print()
CurrentCard.Process(self.__Deck, self.__Discard, self.__Hand, self.__Sequence, self.__CurrentLock, choice, CardChoice)
self.__Discard.AddCard(CurrentCard)
VB.NET:
In order to complete this challenge you need to create a new class called something like RetrievalCard, you need to alter the play game function, you need to alter the setupGame subroutine and you need to create a function to add retrieval cards to the deck. We will look at the Retrieval card class first, then the add retrieval cards function, then the altered setup game subroutine, then the play game function It is worth noting that only the code in the case "U" block has been changed for the playGame() subroutine.

Card count edit
A player loses if they run out of cards in the deck without solving the locks. Therefore they may wish to see this information. Change the program so that alongside the current score the game also displays the number of cards remaining in the deck on each turn.
C#:
//This is from PlayGame
Console.WriteLine("Cards reamining: " + Deck.GetNumberOfCards());
//This a separate function
public static bool DeckEmpty(CardCollection Deck)
{
int NumberOfCardsInDeck = Deck.GetNumberOfCards();
if (NumberOfCardsInDeck == 0)
{
return true;
}
else
{
return false;
}
}
//This is from PlayGame in the switch MenuChoice
case "D":
{
Console.WriteLine(Discard.GetCardDisplay());
bool empty = DeckEmpty(Deck);
if (empty == true)
{
GameOver = true;
}
break;
}
Delphi/Pascal:
Java:
// after line Console.writeLine("Current score: " + score); in Breakthrough.playGame()
Console.writeLine(deck.getNumberOfCards()+" cards remaining in the deck");
Python:
35: print("Current score:", self.__Score)
36: print("Amount of cards in deck: " + str(self.__Deck.GetNumberOfCards())) # Display amount of cards in deck
37: print(self.__CurrentLock.GetLockDetails())
38: print ("Amount counted.")
VB.NET:
Public Sub PlayGame()
cardsLeftInDeck = Deck.GetNumberOfCards()
Console.Write("Cards left in deck: " & cardsLeftInDeck)
Save game edit
There is a load game feature but no ability to save the state of a game. Create one that can be called instead of View Discard or Use Card and saves the game to a file of the users choosing. Also change the Load Game functionality so that the user can enter the name of the file they want to load.
Delphi/Pascal:
Java:
Add a case S into playGame:
case "S": {
Console.writeLine("Please input the filename");
String filename = Console.readLine();
saveGame(filename);
break;
}
And change getChoice:
private String getChoice() {
Console.writeLine();
Console.write("(D)iscard inspect, (U)se card, (S)ave Game:> ");
String choice = Console.readLine().toUpperCase();
return choice;
}
New saveGame()
private boolean saveGame(String fileName) {
try {
BufferedWriter myStream = new BufferedWriter(new FileWriter(fileName));
myStream.append(score + "\n");
int i = 0;
int j = 0;
for (Challenge c : currentLock.getChallenges()) {
if (i > 0 && i < currentLock.getChallenges().size()) {
myStream.append(";");
}
for (String condition : c.getCondition()) {
if (c.getCondition().size() - 1 == j) {
myStream.append(condition);
} else {
myStream.append(condition + ",");
}
j++;
}
j = 0;
i++;
}
myStream.append("\n");
i = 0;
for (Challenge c : currentLock.getChallenges()) {
if (c.getMet()) {
if (currentLock.getChallenges().size() - 1 == i) {
myStream.append("Y");
} else {
myStream.append("Y;");
}
} else {
if (currentLock.getChallenges().size() - 1 == i) {
myStream.append("N");
} else {
myStream.append("N;");
}
}

Speciality deck edit
Currently the game provides a preset set of cards - picks, files and keys. Create a new method to create a SpecialityDeck for an alternative version of the game so the user/player can be provided with an option to play the StandardDeck *or* a SpecialityDeck. SpecialityDeck consists of three types of tool (E)xplosive, (W)elder and (A)nother.

Consecutive Tool Type Penalty edit
Currently no error message is displayed if the user attempts to play two consecutive cards of the same tool type. Change the code to notify the user when their card has been disallowed due to this rule. In addition, leverage a score penalty of 1 point (reduce the user's score by one) and notify the user that this has occurred in all cases except where the user's score would then become negative in which case it should be omitted.

Never reuse locks edit
When a lock is completed a new lock is selected from the list of locks at random. However, it could select a lock that has already been solved by the player. Adjust the method GetRandomLock() in the breakthrough class to fix this.
C#:
private Lock GetRandomLock()
{
Lock NewLock;
do
NewLock = Locks[RNoGen.Next(0, Locks.Count)];
while (!NewLock.GetLockSolved());
return NewLock;
}
Delphi/Pascal:
Java:
private Lock getRandomLock() {
Lock newLock;
do {
newLock = locks.get(rNoGen.nextInt(locks.size()));
} while (!newLock.getLockSolved());
return newLock;
}
Python:
def __GetRandomLock(self):
newLock = self.__Locks[random.randint(0, len(self.__Locks) - 1)]
while newLock.GetLockSolved():
newLock = self.__Locks[random.randint(0, len(self.__Locks) - 1)]
return newLock
VB.NET:
Post Inspection of Discard Pile edit
When playing the game, the player can choose to inspect the discard pile by entering a "D" at their first input. The program is to be amended so that the player can choose to retrieve ONE card from the discard pile and discard ONE card from their hand. The card being retrieved cannot be a difficulty card.
Amend the method PlayGame from the Breakthrough class so that after the user chooses to inspect the discard pile: • the user is prompted to enter a card number to retrieve from the discard pile by entering an integer value for the card. Entering 0 will skip this step. The user should be given the following prompt: "Please enter a number greater than 0 for a card to retrieve. Enter 0 if you wish to skip this step" • the user is then asked to enter a number for the card that they wish to remove from their hand. The user should be given the following prompt: "Please enter a number for the card to discard from your hand" • the cards are transferred between the discard pile and the hand and the game continues
C#:
Delphi/Pascal:
Java:
Python:
#the following added within the PlayGame method
if MenuChoice == "D":
print(self.__Discard.GetCardDisplay())
retrieveCard = int(input("Enter the card you want to retrieve or 0 to skip this step. "))

retrieveCard = int(input("Enter the card you want to retrieve or 0 to skip this step. "))
if retrieveCard != 0:
