My Independent AP CSP Study Reflection
To prepare for the AP Computer Science Principles Exam, I’ve been reviewing CollegeBoard’s multiple-choice questions and studying material shared by classmates, especially blog posts related to Big Ideas 3 and 5. My goal has been to make sure I fully understand each of the required skills and can apply them accurately when faced with different question types on the exam.
Big Idea 5: Impact of Computing Innovations
Beneficial and Harmful Effects
We studied how computing can bring about both positive and negative changes. For instance, social media can help people stay connected but may also affect mental health and spread misinformation. These examples showed how technology must be designed and used with care and consideration for its impact on users and society.
The Digital Divide
We looked at how differences in internet access and digital tools affect communities differently. Some groups, especially in rural or low-income areas, face more barriers to education and work because they lack reliable access. This topic helped me understand why expanding digital access is a key issue in computing.
Bias in Computing
We explored how algorithms can reflect unfair patterns if they are trained on biased data. This includes issues with facial recognition or hiring systems. We talked about ways to reduce bias, like using more balanced datasets and reviewing algorithms for fairness during development.
Crowdsourcing
We discussed how people use the internet to work together on projects, like editing Wikipedia or contributing to open-source code. While this approach allows many voices to contribute, it also creates challenges in maintaining accuracy and quality.
Legal and Ethical Issues
Our study included topics like copyright, data privacy, and how companies handle user information. We considered questions like whether users are fully informed when their data is collected. These conversations helped us think through the responsibilities that come with creating and managing technology.
Safe Computing Practices
We reviewed ways to protect ourselves online, including strong passwords and multi-factor authentication. We also discussed common threats, like phishing and malware, and how to respond to them. These lessons helped reinforce the importance of acting responsibly in digital spaces.
Big Idea 3: Algorithms and Programming
Binary Search
We learned how binary search works by repeatedly dividing a sorted list to find a value. This method is faster than linear search for large datasets. Writing the code ourselves helped show how conditions and loops work in real situations.
Lists and Filtering
We practiced building programs that use lists and filters to sort or search through data. This helped us understand how iteration and selection are used to solve real problems, such as organizing information or finding matches in a dataset.
Big-O Notation
We studied how Big-O notation helps describe how an algorithm performs as the input size increases. We compared different kinds of algorithms—like constant, linear, and quadratic—to see which ones are more efficient, especially for large tasks.
Randomness in Programs
We looked at how randomness can be used in computing, such as in games or simulations. These lessons showed how random values can be useful in creating variety or modeling uncertainty.
Simulations
We saw how simulations allow us to test systems without real-world consequences, like predicting traffic patterns or climate change. We also talked about the importance of understanding the limits of a simulation based on its assumptions.
Undecidable Problems
We explored problems that computers can’t fully solve, like the Halting Problem. These lessons helped us understand the limits of what computing can do and why not every question has a programmable solution.
Graphs and Heuristics
Finally, we studied how graphs can represent relationships, such as in navigation apps. We also used heuristics, which are shortcuts or strategies to find solutions when exact methods are too complex. These tools are useful in many types of real-world problems.
How to Keep Studying
To improve and continue studying effectively, I plan to review key concepts from each Big Idea using flashcards and targeted practice questions. I’ll regularly revisit MCQs from CollegeBoard and teach material to classmates for reinforcement. By rotating topics weekly and tracking progress, I’ll ensure steady growth. I’ll also practice simulations and algorithms to deepen my understanding of computational thinking and exam-ready problem solving.

General Tips
Big Ideas:
- Big Idea 1: Creative Development
- Big Idea 2: Data
- Big Idea 3: Algorithms and Programming
- Big Idea 4: Computer Systems and Networks
- Big Idea 5: Impact of Computing
Multiple Choice Section Tips
- Read Carefully: Especially for “Select two correct answers” or “Which best explains…?” type questions.
- Sketch it out: For logic problems, draw the code path or flowchart if you’re visual.
- Use process of elimination: Cross off options that clearly violate logic or syntax.
For logic questions, remember:
- Loops execute while a condition is true.
- IF statements branch based on a condition (watch your nesting!).
For Internet/Cybersecurity questions:
- Understand encryption, packets, IP addresses, and DNS.
- Know examples of metadata and phishing vs. malware.
Create Task Tips (Reflection)
Even though it’s submitted, review your logic:
- Could you explain your abstraction?
- Do you use data clearly and meaningfully?
- Did you cite any borrowed code?
- Be able to identify what was required in your Create Task and reflect on it in practice prompts.
Study Hacks
- Use Quizlet: Prioritize terms in Big Idea 2 (data types, metadata) and Big Idea 3 (functions, parameters, loops).
- Do timed mini-quizzes daily.
- Group study: Teach a topic to someone else—it boosts retention.
- Redraw pseudocode from memory: Great for abstraction and logic practice.
2021 MCQ Review
Score:
62/70
Reflection:
I took 1 hour and 41 minutes which is a good time as 2 hours is allowed. This is an improvement for me based on past MCQs as before I went over the time limit. I excelled on the topics my team taught and on the logic questions, but struggled a little more on the technical questions.
Topic Breakdown:
Areas I need to work on:
3.10: Lists – Scored 20%
This was my lowest-scoring section. I plan to review how to create, access, modify, and iterate through elements in lists, as this is a foundational skill in programming.
-
3.3: Mathematical Expressions – Scored 33%
I need to strengthen my understanding of arithmetic expressions, particularly the order of operations and how they are evaluated in code. -
3.7: Nested Conditionals – Scored 50%
I will practice interpreting and constructing nested conditional statements to better understand the logic flow and improve accuracy. -
3.15: Random Values – Scored 50%
I intend to revisit how random values are generated and implemented in programs, especially in simulations and games. -
2.1: Binary Numbers – Scored 71%
I need to reinforce my knowledge of binary representation and conversions between binary and decimal systems. -
1.4: Identifying and Correcting Errors – Scored 80%
While not a low score, I believe there is room for improvement in debugging and correcting both syntax and logic errors. -
3.12: Calling Procedures – Scored 80%
I plan to review how procedures are defined and called, including understanding the use of parameters and return values.
Areas of Strength
I demonstrated strong understanding across a wide range of topics, scoring 100% in areas such as collaboration, program function and purpose, data analysis, conditionals, iteration, internet principles, and computing ethics. These results suggest a solid foundation in both the technical and conceptual aspects of computer science principles.
Next Steps
I will focus my review and practice on the topics where my performance was below 80%, particularly in list manipulation, mathematical expressions, and nested conditionals. Additionally, I will continue to reinforce and maintain my understanding in the areas where I performed well. I can also use the extra practice that was posted on College Board.
