What is the AP Computer Science a exam?
THIS PAGE IS INTENTIONALLY LEFT BLANK. The AP Computer Science A Exam assesses student understanding of the computational thinking practices and learning objectives outlined in the course framework. The exam is 3 hours long and includes 40 multiple-choice questions and 4 free-response questions.
Question 1: Methods and Control Structures
This question involves the use of check digits, which can be used to help detect if an error has occurred when a number is entered or transmitted electronically. An algorithm for computing a check digit, based on the digits of a number, is provided in part (a). The CheckDigit class is shown below. You will write two methods of the CheckDigit class
/** Returns true if numWithCheckDigit is valid, or false
otherwise, as described in part (b). Precondition: The number of digits in numWithCheckDigit is between two and seven, inclusive. * numWithCheckDigit >= 0 */ public static boolean isValid(int numWithCheckDigit) AP Computer Science A Course and Exam Description apcentral.collegeboard.org
Applying the Scoring Criteria
Apply the question scoring criteria first, which always takes precedence. Penalty points can only be deducted in a part of the question that has earned credit via the question rubric. No part of a question (a, b, c) may have a negative point total. given penalty can be assessed only once for a question, even if it occurs multiple times or in mul

v) Array/collection access confusion ([] get) w) Extraneous code that causes side-effect (e.g., printing to output, incorrect precondition check) x) Local variables used but none declared y) Destruction of persistent data (e.g., changing value referenced by parameter) z) Void method or constructor that returns a value apcentral.collegeboard.org
Question 3: Array/ArrayList
The Gizmo class represents gadgets that people purchase. Some Gizmo objects are electronic and others are not. A partial definition of the Gizmo class is shown below. public class Gizmo { /** Returns the name of the manufacturer of this Gizmo. */ public String getMaker() { /* implementation not shown */ } apcentral.collegeboard.org
/** Returns true
* otherwise. */ if this Gizmo is electronic, and false public boolean isElectronic() { /* implementation not shown */ } apcentral.collegeboard.org
/** Returns true if this Gizmo is equivalent to the Gizmo
object represented by the parameter, and false otherwise. */ public boolean equals(Object other) { /* implementation not shown */ } // There may be instance variables, constructors, and methods not shown. } The OnlinePurchaseManager class manages a sequence of Gizmo objects that an individual has purchased from an online vendor.
