The course emphasizes problem-solving, critical thinking, and collaboration.
What is AP Comp Sci?
AP Computer Science Principle is an important course that's perfect for high-schoolers who want to pursue computer science technology from the basics for their other leanings.
It's designed to be flexible, so students who lack prior knowledge of computer science can still learn and excel. The course doesn't hold any particular programming language, making it accessible to underrepresented students.
AP Computer Science Principle is prepared to be aligned with introductory courses of computing and technology offered in colleges and universities. This means students can easily transition to more advanced courses.
By learning the basics and necessities of AP computer science, students can choose their own preferred programming language to learn or explore. This course offers a complete knowledge of how bits and bytes work, which is essential for investigating new technologies in the computer science field.
Students who take AP Computer Science Principle are 16.9% more likely to major in Computer Science in college compared to non-takers, who have a 5.2% chance of doing so.
Study Tips
Learning to code early is key to success in AP Computer Science A. Students who start coding early and practice often will have increased confidence and a better chance of doing well on the AP CSA exam.
To prepare for AP CSA, students can take live online classes or explore online resources like Intro to Java Programming, Learn Java Online, Codecademy, and W3Schools. These resources can help students learn the basics of coding and programming.
A different take: How to Learn to Code for Beginners
CodeWizardsHQ courses provide students with the foundational coding and programming skills needed to succeed in AP Computer Science A. Students who already have these skills will find it easier to make sense of the course content and exams.
Practice tests are a great way to feel prepared and confident for exams. Free practice test sites like Albert.io, Smore's list of APCS resources and practice tests, and Varsity Tutors can be used to help students prepare for the AP Computer Science exams.
To get the most out of practice exams, students should pay attention to their results and create a notebook with questions they answered incorrectly, along with their correct answers. This will help them identify areas where they need to improve and focus their studying.

Section II: Performance Task
The performance task in Section II of the AP Computer Science Principles Exam assesses Computational Thinking Practices 1, 2, 3, and 4 across six rubric rows. This task is done throughout the course and evaluates students' skills in explaining code segments, using abstraction, and implementing algorithms.
Students' ability to explain how a code segment or program functions is assessed in Row 1, Program Purpose and Function. This skill is crucial in understanding how a program works and is essential for debugging and troubleshooting.
Row 2, Data Abstraction, evaluates students' ability to use abstraction to manage complexity in a program. This skill is closely related to Procedural Abstraction, which is assessed in Row 4.
Managing Complexity, assessed in Row 3, requires students to explain how abstraction manages complexity. This skill is essential in programming, where complexity can quickly become overwhelming.
Algorithm Implementation, assessed in Row 5, evaluates students' ability to implement and apply an algorithm. This skill is critical in computer science, as algorithms are the building blocks of programs.
The performance task also assesses students' ability to investigate the situation, context, or task, which is evaluated in Row 6, Testing.

Best Course
Most students find it difficult to choose the best AP computer science course.
The AP Computer Science Principles course is often considered the easiest, with an average score of about 2.6 / 10.
AP Computer Science A has an end of course exam based on multiple choice questions and free response questions.
AP CS Principles, on the other hand, has a create performance test and a multiple choice based exam.
Both courses are different in terms of exam formats, which can make a big difference in how you study.
Scoring and Evaluation
The AP Computer Science A exam is scored based on a combination of multiple-choice and free-response sections. Each section accounts for 50% of the total composite score.
Raw scores are scaled along a grading curve and converted to the 1-5 AP scores, which is a crucial aspect of the exam. This process ensures that students are evaluated fairly and consistently, regardless of the specific questions on the exam.
To give you a better idea of the scoring process, here's a breakdown of how the exam is evaluated:
- Multiple-choice sections: 50% of the total composite score
- Free-response sections: 50% of the total composite score
What Is Equivalent To?
The AP CS A course is aligned to cover one-semester equivalent college first year course.
This means that if you do well in AP CS A, you'll likely be well-prepared for a first-year college computer science course.
Section II: Free-Response
The free-response section of the AP Computer Science A Exam is a crucial part of the test, and it's essential to understand what to expect.
You'll be given four free-response questions that assess Computational Thinking Practice 3: Code Implementation. These questions are designed to test your ability to implement code and think computationally.
The free-response questions are divided into four types, which are:
- Methods and Control Structures
- Class
- Array/ArrayList
- 2D Array
To succeed in the free-response section, it's essential to practice identifying the proper parameters to use when calling methods of classes that are provided to you. Pay close attention to the method descriptions and use the correct type and order of parameters when calling methods.
You can find practice free-response questions and resources to help you prepare at Albert.io, AP College Board APCSA Past Exam Questions, CodeHS practice problems, and Smore’s list of APCS resources and practice tests.

What Is a 3 Score on the ACT?
A 3 score on the ACT is a respectable achievement, considering that 21.7% of students earned a 3 on the exam. This score indicates that you've done well, but not exceptionally well.
To put it into perspective, a 3 on the ACT means you've answered about 55% of the questions correctly. This is a good starting point for college admissions, but it's not a guarantee of acceptance.
The College Board's score distributions show that a 3 is a solid score, but it's not the highest you can aim for. If you're looking to impress colleges, you may want to aim for a higher score.
Keep in mind that a 3 on the ACT is a significant achievement, and it's a good indicator of your academic skills.
