2023 AMC 10A Exam Analysis: Difficulty, Structure, and Strategies

In this comprehensive analysis, Think Academy’s math experts delve into the recently concluded 2023 AMC 10A competition, exploring overall difficulty levels and question structures. From the initial set of relatively basic questions to the concentration of geometry in the moderate difficulty range, and finally, to the last five particularly challenging questions, our analysis unveils patterns and nuances that shape the examination landscape. Our module-specific breakdown sheds light on the varying levels of difficulty and the knowledge proficiency required in each area. Additionally, we identify error-prone questions and tricky questions,  providing effective answering strategies. Read on! 

Overall Difficulty Levels

The question difficulty is relatively moderate, and the final questions are less complex than anticipated.

1.  Easy questions start from a basic level, but none are absolute giveaways. Unlike prior years where the first question was a straightforward calculation, this year’s initial question involved a problem-solving scenario, not difficult but requiring multiple steps, without offering complete free points. Additionally, within the first 10 questions, the 7th and 9th questions are prone to errors, challenging students’ mindset when placed at the beginning.

2. Moderate-difficulty questions focus primarily on geometry. While the tested geometry knowledge areas are similar to previous years, there are no exceptionally difficult or time-consuming questions. Many questions can be solved with a clear approach, and the 16th question, the most challenging in geometry, requires an analysis combining some number theory knowledge.

3. The last 5 questions do not present particularly challenging situations, and familiarity with core concepts is generally sufficient for quick resolution.

Overall, this exam assesses students’ attention to detail in various aspects. Meticulous students are likely to score significantly higher, leading to overall scores that could be either very high or very low.

Algebra: Varied Difficulty Levels

• Algebra questions encompassed 7 problems.
• Concentration is observed in the initial 10 and final 5 questions.
• Surprisingly, no algebra questions were found in the 11-20 range.
• A distinct polarization in difficulty is evident.
• Topics covered include basic operations, fractions, mean, exponentiation, polynomials, and algebraic expressions with integer solutions.
• Notably, the customary examination of arithmetic progression is omitted.

Geometry: The Key to High Scores

• Geometry consisted of 10 questions.
• Six geometry questions were concentrated in the 11-20 range.
• Two geometry questions were present in both the initial and final 10 questions.
• There is a lack of exceptional difficulty in geometry questions.
• Covered topics encompass square/triangle/circle areas, tangency of circles, regular polygons, and the Pythagorean theorem.
• Adherence to standard planar geometry concepts is evident.
• Proficiency in geometry correlates with higher scores.
• Solid Geometry:
  • Three questions touched on the topic.
  • There was no delve into pure solid geometry concepts.
  • Question 6 focused on cube geometry.
  • Question 18 explored Euler’s theorem.
  • Question 25 addressed a polyhedron’s properties.
  • The absence of topics like cylinders and cones raises curiosity about their potential inclusion in subsequent sections.

Combinatorics: Emphasis on Counting Principles and Probability

• The examination’s approach to combinatorics remains consistent, focusing on counting principles and probability.
• Among the six combinatorial questions, five were centered on counting principles and probability (3 probability + 2 counting).
• An additional question delved into the realm of sports competitions.
• The last question on counting and probability exhibited a distinctive characteristic, testing students’ understanding of spatial geometry.
  • Knowing the properties of a specific geometric shape facilitated a quick solution.
  • Lack of familiarity with the three-dimensional figure made the question considerably challenging.
• The other counting and probability questions intricately interwove various knowledge domains, extending beyond the realms of pure combinatorics.

Strategies for Tackling Error-Prone and Tricky Questions

Error-Prone Questions and Answering Strategies

Question 9: This falls within the realm of counting problems and is particularly prone to undercounting issues during enumeration. Additionally, it involves considerations related to months and dates, making it unsuitable for the direct application of addition, multiplication principles, or permutation and combination formulas.

Question 19: This problem entails the rotation of geometric figures in a coordinate system. Many students may mistakenly interpret it as the intersection of lines AB and A’B”, but, in reality, it represents the intersection point of the perpendicular bisector lines.

Tricky Questions and Answering Strategies

Question 7: Probability problems involving the dynamic sum of dice points are relatively rare in the AMC10. The wording of the question may pose a challenge during the reading process, leading to a significant investment of time in comprehension. However, once the question is fully understood, the difficulty in solving it is not substantial.

Question 13: This is a geometric angle problem that essentially involves the sine theorem. In the context of the AMC10, the concept of central angles can be utilized to solve it. This approach provides a significant advantage for students in the Think program. We will instruct students on how to construct the diagram for this problem.

Question 18: This problem is, in fact, an examination of Euler’s theorem. While many students are familiar with Euler’s theorem and may use it to validate certain geometrical properties, there are instances during problem-solving where they might struggle to apply it. Knowing Euler’s theorem makes this particular question straightforward and quickly solvable.

Congratulations on qualifying for the 2027 AIME! As you begin preparing, your progress in Algebra 2 can help you decide what to study first.

If you haven’t started Algebra 2 or are still studying it, some AIME problems may involve material you haven’t covered yet. Check whether you have studied logarithms, complex numbers, and trigonometry. Any unfamiliar topics will need attention alongside your competition practice.

If you have already studied these topics, focus on using them in longer solutions. For example, you may need to combine divisibility rules with counting, connect several geometry theorems, or rewrite a recurrence before you can calculate the requested answer.

Our free AMC 10 & AMC 12 Post-Exam Resource Pack brings together exam review, AIME preparation guides, and additional practice to help you choose where to begin.

Inside, you’ll find:

• 2026 AMC 10 & AMC 12 papers and solutions to review missed questions and understand the methods behind the answers.
• From AMC 10 to AIME Guide to distinguish topics you may need to learn from familiar topics that require deeper study.
• From AMC 12 to AIME Guide to compare the knowledge and problem-solving depth expected on the two exams.
• AIME practice problems to work on applying and connecting ideas.
• AMC 10 practice problems to revisit topics that need more practice.

Both guides include selected official AIME problems, hints, complete worked solutions, and a learning checklist. For each example, read the foundation first, try the problem independently, then use the hints and solution to review your approach.

Start with your 2026 paper and solutions to identify where you struggled. Then use the guide that matches your AMC background to decide whether to learn a topic, review it, or practice applying it in more demanding problems.
