Haley Shea
Elementary Statistics Tutor • +143 Subjects
Haley graduated from the University of North Georgia with two bachelor's degrees in English Writing & Publication and Interdisciplinary Studies (Mathematics/Technology, Social Science, and Humanities concentrations), and an associate's degree in Psychological Science (2020). Previously, she completed an associate's in Communication, Film & Digital Media Studies (2016). While at UNG, she worked as a Writing Center Peer Consultant, Supplemental Instruction Facilitator, English Department Student Administrative Assistant, Writing Fellow, and Ambassador for the Center for Undergraduate Research & Creative Activities (in addition to programming stimulus displays for EEG experiments in the neuroscience lab). Her major fields of study are supplemented by three minors: Linguistics, Psychology, and Studies of English Language Learning. Combined, this background enables a flexible tutoring approach that can be customized to meet the needs of both additional-language learners and individuals facing cognitive challenges. Haley Shea is currently pursuing graduate-level education in cognitive science, conducting neuroscientific laboratory research in psycholinguistics and brain-computer interface, and training for a career in human-computer interaction. During college, her top subjects were Advanced English Grammar and Linguistics. There, she was known for her passionate leadership of study sessions for sentence-diagramming, which inspired her laboratory research. An active community member, she was Vice President of the English Honor Society chapter and led the UNG Writers Guild for two years, helping students write and gather valuable feedback from one another, enabling them to better proofread and edit their work for future publications. Many of those writers saw their work in print through UNG's award-winning student literary magazine, for which Haley Shea served as an editor for several years. Other campus engagements included running the community book drive for over two years and founding an all-student improv troupe which went on to perform and compete in tournaments around the state and region. While acting helped her become comfortable on-stage, Haley Shea also greatly benefited from her time as a member of the speech and debate team, placing first in statewide debate and slam poetry competitions over the years. Her favorite topic of both debate and poetry is that of human innovation and interaction with emerging technology, especially in relation to ethical policies on artificial intelligence. Captivated by syntax in both spoken language and computer code, she is fascinated with recent developments in language-based software and hopes to contribute to the field of computational psycholinguistics while earning her PhD. After graduating, Haley Shea knew she wanted to keep supporting other students toward their goals. A scholarship student herself, she always loves any chance to help individuals express their strengths and unique personal histories in ways that will help further their goals. To this end, she continues to mentor applicants for nationally competitive scholarships and other student support opportunities, such as the McNair Scholars Program and Goldwater STEM Scholarship, two major awards which made an immense difference toward the funding of her bachelor's education when she was named an official recipient in 2019, in honor of her interdisciplinary research and commitment to fostering student success on campus. She finds joy in any opportunity to uplift other students--especially women in STEM, individuals facing disabilities, or anyone who seeks to improve their command of the English language. In sharing her passions with her students, she helps them break out of "analysis paralysis" into a fun, personalized routine that helps foster positive associations with the topic of study and strong metacognitive skills that lead to improved performance over time. Special Topic Announcement: Students of English writing, grammar, comprehension, et cetera may enjoy developing their meta-linguistic awareness through Sentence Diagramming. Ask during booking to learn more about how you can become a grammar wiz through one-on-one classes in Sentence Diagramming taught by Haley Shea.

Frequently Asked Questions
Students typically find object-oriented programming concepts—especially inheritance, polymorphism, and encapsulation—challenging to grasp initially. The 2D array manipulation and ArrayList operations also trip up many students, particularly when combined with nested loops and algorithmic thinking. Additionally, the transition from procedural thinking to designing classes with proper method decomposition often requires targeted practice, and students frequently underestimate the importance of understanding how the AP exam's GridWorld or other case study frameworks apply these core concepts.
The exam splits into two sections: a 90-minute multiple-choice section (40 questions) testing conceptual understanding and code reading, and a 90-minute free-response section (4 questions) requiring students to write and debug code. Many students underestimate the multiple-choice section's difficulty—it requires not just knowing syntax but understanding what code does without running it. Effective tutoring addresses both skills: building speed and accuracy in reading unfamiliar code, and developing the ability to design solutions and explain your reasoning clearly in free-response questions.
Recursion requires students to think about problems in a fundamentally different way than the iterative loops they've mastered, and many struggle to visualize the call stack or trust that the recursive case will eventually terminate. The challenge intensifies when recursion is combined with arrays or strings, or when students need to trace through multiple recursive calls mentally. A tutor can break down recursion using visual tools like call stack diagrams and simplified examples, then gradually build complexity so students develop intuition rather than just memorizing patterns.
Free-response questions reward clear design and partial credit heavily—writing pseudocode or outlining your approach first prevents costly mistakes and earns points even if your code isn't perfect. Students should spend 2-3 minutes planning before coding, identifying what variables and loops they'll need. Tutoring focuses on teaching students to read prompts carefully for edge cases, write modular helper methods rather than one giant solution, and practice writing clean, readable code quickly so they can verify logic under pressure.
The multiple-choice section frequently presents buggy code or asks students to predict output without running it—skills that require deliberate practice. Tutors work through code-tracing exercises systematically, teaching students to track variable values through loops and method calls, spot off-by-one errors, and recognize common mistakes like null pointer issues or incorrect loop bounds. Regular practice with released AP exam questions builds pattern recognition so students can quickly identify problems and understand why code behaves unexpectedly.
With 90 minutes for 40 multiple-choice questions, students should aim for roughly 2 minutes per question, but skipping difficult questions and returning to them saves time and confidence. For free-response, allocating 20-25 minutes per question allows time for planning, coding, and review. Tutoring includes timed practice tests to help students find their rhythm, identify which question types slow them down, and develop strategies like solving the easiest free-response question first to build momentum.
Students who struggle with foundational concepts (loops, arrays, methods) typically see the biggest gains—often 2-3 score levels—when they close those gaps through focused tutoring. Students already scoring 3s or 4s can reach 5s by sharpening free-response writing clarity and eliminating careless mistakes on multiple-choice through deliberate practice. The timeline depends on starting point and consistency, but 8-12 weeks of regular tutoring combined with independent practice typically produces meaningful improvement.
Beyond strong Java proficiency and understanding of AP exam content, an effective tutor should have experience teaching object-oriented design, recognizing common student misconceptions, and explaining abstract concepts like recursion and polymorphism clearly. Familiarity with the specific AP case study (GridWorld or others) and access to released exam questions is important. Ideally, tutors have either taught AP Computer Science or scored well on the exam themselves and understand the exact skills the exam tests.
