Overview of Each Exam
Each AP exam is not only about information recall, but also an assessment of close analysis and interpretation. When you’re well-informed about each course’s test format, you’ll improve your chances of scoring high on the final exam, and come one step closer to earning college credit.
The AP Computer Science exam lasts a total of 3 hours. Exam content refers to AP Java subscript. Accordingly, all test questions should be answered in the Java format. The test is broken down into two sections. In Section I, students are given 1 hour and 30 minutes to respond to 40 multiple-choice questions. Examples of questions include data structures, programming fundamentals, object-oriented programming, data structures, logic, algorithms/problem solving, software engineering, and recursion. This portion of the exam accounts for 50% of the overall score.
Section II of the AP Computer Science exam centers on four Free Response questions, which students are given 1 hour and 30 minutes to answer. In a short-answer format, students must respond using Java programming language. In addition, you will solve problems using in-depth reasoning. Section II of the exam will account for 50% of the overall exam score.
For example, students may be asked to identify best object-oriented program design needed at a car dealership scenario, or for the program which best suits a flight company tracking incoming and outgoing flights each day. In this way, students will put their skills to the test in real-life situations.
On the other hand, the AP Computer Science Principles’ final score is based on an official exam grade as well as through-course assessments. The AP Computer Science Principles exam lasts a total of 2 hours. During the exam, students are to answer 74 multiple-choice questions in 120 minutes. Some questions ask students to choose only one correct answer, while others may require multiple selections within a single question. The exam accounts for 60% of the overall assessment score.
Students must also carry out two through-course performance tasks, worth the remaining 40% of the overall assessment score. In the first task, students are tested on the Impact of Computing Innovations. Students are given 8 hours of class time to complete this portion of the assessment, which is awarded 16% of the assessment score.
Secondly, students conduct a task referred to as the Application to Ideas. Students are given 12 classroom hours to complete this section. It is worth 24% of the assessment score.
For example, in the exam portion of the assessment, students may be asked to assess the result of running a code segment given two variables. Alternatively, during the performance task portion, students may be asked to develop computer programs and explain aspects which allow the program to function.
Key Differences in the Curricula of Each Course
AP Computer Science A versus AP Computer Science Principles are considered complimentary courses. That is to say, neither is a prerequisite for the other. Students are encouraged to take a close look at the curriculum and goal sets of each to better determine which course they should take.
AP Computer Science A hones your skills in developing Java script programming. Over the duration of the course, you will develop learning skills that include problem solving, design strategies and methodologies, data organization, data processing, examination of potential solutions, and understanding of social and ethical computing practices. AP Computer Science A is considered compatible with CS1 courses.
The course is broken down into lab activity and computer language practice. You’ll be given no less than 20 hours of hands-on lab activity in which your main goal will be problem solving: individually or in groups. Major objectives include designing problem solutions, expressing solutions succinctly, testing solutions, and weighing possible solutions.
You’ll also be developing Java script skills during the computer language portion of the course, as all problem solutions must be written in Java. However, AP Computer Science A is an introductory course. For this reason, lessons in Java should also be considered an introduction, but not an exhaustive course as it would be too much to include in a single class.
Overarching goals of this course include implementing and analyzing potential problem solutions, utilizing common algorithms, using data structures and algorithms to carry out new problems, writing out clear solutions, testing and debugging solutions given Java script programming, reading and understanding programming and the development process, and understanding social implications of computing.
On the other hand, AP Computer Science Principles equips you with the discipline necessary to analyze and draw conclusions about large sets of data. The course will call on you to be creative in problem solving computing problems. In addition, you must work collaboratively to design, analyze, and experiment with potential design concepts in groups. Big picture, you’ll also start to consider the ethical and social ramifications of computing.
AP Computer Science Principles, versus AP Computer Science A, does not specify a computing language. Each teacher selects a language for the class to be conducted in.
Major studies within the AP Computer Science Principles course include creativity, abstraction, data and information, algorithms, programming, internet, and global impact. Additionally, as AP computing students, you’ll focus on drawing connections between concepts, analyzing problems and artifacts, abstracting, creating computational artifacts, communicating the impact of technology and computation, and collaborating as a group to come to collective conclusions.
Pros and Cons for Taking Each Course
When you glance at both curricula, you’ll notice there’s overlap in exam format and course content. Both classes will develop your ability to analyze and problem solve effectively. The major difference between AP Computer Science Principles and AP Computer Science A lays in the spectrum of the material covered.
AP Computer Science A offers a more narrowly focused course. Students with a predisposition or particular interest in pursuing Java script computing should consider enrolling in this course. Given its compatibility with CS1 courses at many American colleges, students can begin to look at the course as an avenue for future study.
Before taking the course, you should have a basic foundation of English and algebra. You should also have some familiarity with functions and the concepts found in the uses of function notation. Lastly, basic mathematical understanding is also a key to success in this type of course.
Contrarily, AP Computer Science Principles is a broadened look at computing practices. Since language is not specified, you’ll have the advantage of being exposed to one or more computing languages. Especially in the case that you’ve not yet narrowed down where future computing interests are, AP Computer Science Principles offers a comprehensive sampling.
It’s strongly suggested that you’ve already taken a high school algebra course prior to enrolling in AP Computer Science Principles, with a special emphasis on functions and problem solving strategies that may require more than one approach. It’s important students have exposure to the Cartesian (x, y) coordinate system as well as a foundation in mathematics before starting the course.
What Sort of Student May Excel in Each Course
