AP Statistics
A 20-session AP Statistics exam preparation program.
Overview
A 20-session program — roughly 10 weeks — preparing students for the AP Statistics exam, aligned with the College Board’s revised framework effective Fall 2026. Each unit pairs concept sessions with graded problem-solving and evaluation, and the program concludes with full-length timed mock exams and review.
Instructor Profile
- Applied Mathematics and Statistics major at Stony Brook University (rising junior)
- Relevant Teaching Experience: Teaching Assistant for AMS 310: Survey of Probability and Statistics at Stony Brook University (Spring 2026)
- College statistics coursework: AMS 310 (Survey of Probability and Statistics), AMS 394 (Statistical Laboratory), and AMS 315 (Data Analysis), with AMS 311 (Probability Theory) and AMS 317 (Introduction to Linear Regression Analysis) in Fall 2026
- Scored a 5 on AP Statistics exam (2024)
Learning Outcomes
The course is built around the four statistical practices defined in the AP Statistics Course and Exam Description:
- Formulate Questions: determine a valid investigative question for a statistical study.
- Collect Data: identify and justify methods for collecting data and conducting statistical inference.
- Analyze Data: construct representations of data and calculate numerical statistical outputs.
- Interpret Results: interpret results and justify conclusions and the methods behind them.
Curriculum
The course covers all five units of the AP Statistics exam as outlined in the CED. Because the units differ greatly in size, sessions are allocated by weight and topic count. Each unit pairs concept sessions with problem-solving sessions, and the program closes with three full-length mock tests.
| Unit | Exam weight | Sessions |
|---|---|---|
| 1. Exploring One-Variable Data and Collecting Data | 20–30% | 1–4 |
| 2. Probability, Random Variables, and Probability Distributions | 15–25% | 5–8 |
| 3. Inference for Categorical Data: Proportions | 15–25% | 9–12 |
| 4. Inference for Quantitative Data: Means | 10–20% | 13–15 |
| 5. Regression Analysis | 10–20% | 16–17 |
| Exam Review | — | 18–20 |
A typical concepts session
- Before session: a short 10-minute warm-up video is assigned to introduce the unit.
- During session: the instructor works through the unit’s concepts using the provided notes, worked examples, and visualizations.
- After session: a short review quiz is assigned to check understanding.
A typical problem-solving session
- Before session: an exercise set of 40–50 practice problems is assigned; the instructor grades it and returns written feedback.
- During session: the instructor selects the problems the student struggled with and works through them together.
- After session: a report outlining suggestions for improvement is provided, along with a follow-up exercise set of variable length.
Materials
- All notes are developed and provided by the instructor.
- Two practice textbooks:
- 5 Steps to a 5: 500 AP Statistics Questions to Know by Test Day
- The Princeton Review AP Statistics Premium Prep (latest edition)
Format
Sessions are held online via Google Meet, or in person in Songdo or Gangnam. A mixed arrangement also works; for example, one online and one in-person session each week. The format is confirmed during the introductory call and can be adjusted by session as needed.
Pricing
70,000 KRW per session. A standard session runs 1.5 hours and is inclusive of all out-of-session work, including problem-set grading, written feedback, and individualized improvement reports.
Time beyond the 1.5-hour block, when needed, is billed at 15,000 KRW per additional 30 minutes. Tuition is billed monthly in advance at the start of each calendar month.
Policies
- Enrollment and payment: The program runs on a monthly contract of two sessions per week. The monthly fee is due before the first session of each month.
- Refunds: A refund is available only if requested before the first session of the month begins; once the month has begun, fees are non-refundable.
- Cancellations and no-shows: Cancellation of a scheduled session by the student must be reported at least 24 hours in advance. Sessions cancelled with proper notice are rescheduled at no cost. Cancellations made less than 24 hours in advance are treated as no-shows and charged in full. A late arrival does not extend the session beyond its scheduled end time.
- Instructor-initiated changes: If the instructor must cancel a session, notice is given at least 24 hours in advance and the session is rescheduled at no cost — no session is lost.
- Preparation: Students complete all pre-session assignments before each session.
- Venue costs: For in-person sessions, any venue or space costs (such as a study café) are covered by the student.
Getting Started
A short introductory call is available at no charge to discuss the student’s goals, current level, and scheduling before any commitment.
