If you’re a middle schooler in Johns Creek or Duluth planning to take the AMC 8 this year, this is a good time to start preparing. Twelve weeks gives you enough room to build your skills steadily.
The 2027 AMC 8 runs from January 21 to 27. With a 12-week plan, you can finish your main preparation before the contest window opens. That gives you time to work through unfamiliar problem types, review your mistakes, practice under time pressure, and slow down in the final days instead of cramming.
Today, our education specialists at Mathnasium of North Johns Creek will take you through each week, from your first practice test to your final review before contest day.
The AMC 8 gives you a chance to practice the kind of thinking you’ll use in more advanced math:
choosing how to represent a problem
checking your reasoning
managing your time
explaining how you got your answer
Before you start preparing, make sure you know where you’ll take the contest. You sign up through an approved competition site, usually your school. Sites follow their own registration deadlines:
October 28, 2026, is the early-bird deadline.
January 5, 2027, is the final day for a new competition site to register.
Check with your math teacher to see whether your school is hosting. Otherwise, ask your parents to help you check the MAA’s public list of registered sites and find another place nearby where you can take the AMC 8.
What’s on the test? The AMC 8 gives you 40 minutes to answer 25 questions covering:
Counting and probability
Estimation
Elementary geometry, including the Pythagorean Theorem
Spatial visualization
Interpreting graphs and tables
Early algebra
To keep your preparation organized, you can follow this week-by-week plan.
Your first step is to take one full past AMC 8 under real contest conditions:
Choose a recent test with full solutions from the Art of Problem Solving AMC 8 archive.
Set a timer for 40 minutes.
Work through all 25 questions somewhere quiet so the experience feels as close to contest day as possible.
Do not use a calculator.
Try not to treat your first score like a final judgment. Think of it as a map showing where you’re losing points and what deserves more attention. If you’re in 5th or 6th grade, a lower score on your first attempt is completely normal. You’re working on a test designed for students through 8th grade.
When students come to Mathnasium for support, they begin with a diagnostic assessment so we can see where their understanding starts to break down. From there, we build a personalized learning plan that targets the specific gaps we found.
You can take the same approach with your practice test. Instead of only counting wrong answers, look at the reason behind each one.
Start by sorting every missed or skipped question into one of these four types:
|
Error type |
Example |
What to do next |
|
Content gap |
Review the concept, then solve 3–5 similar problems. |
|
|
Reading error |
You solved for the radius when the question asked for the diameter. |
Underline what the question is asking for, including any required units. |
|
Approach error |
You chose a slow or unworkable method, such as using algebra when a diagram or casework would be faster. |
Write down the clues you missed, such as “draw first,” “make a table,” or “try small cases.” |
|
Arithmetic slip |
Do a short accuracy drill, then rewrite the step correctly. |
Then, you may keep these sorted misses in an error log, either in a notebook or a document. For each one, record the type of mistake and what you’ll do differently next time. You’ll use that log to guide the practice blocks that follow.
You can start with the skills that caused problems on your Week 1 test, then work them into your AMC 8 practice, focusing on:
Averages and estimation
Divisibility, factors, multiples, and remainders
Integer reasoning
Let your error log decide where you spend the most time. If fractions caused several misses but averages did not, give fractions the extra practice.
We also recommend mixing several of these skills in your review session instead of doing a long set of one problem type. For example, you might solve a percent problem, then a divisibility problem, followed by a ratio or estimation question.
This idea was supported by a large classroom trial by Rohrer et al. (2020). Seventh graders who used interleaved practice scored 61% on a delayed test, compared with 38% for students who used blocked practice.

Over weeks 4-5, turn your attention from number sense to the visual side of the AMC 8:
Coordinate geometry and the Pythagorean Theorem
Symmetry and nets
3D reasoning and spatial visualization
The geometry questions on the AMC 8 expect you to use spatial reasoning rather than simply apply the right procedure or formula. According to research by Jones (2013), diagrams can help connect written information, visual features, and mathematical reasoning. So, treat the diagram like a tool you can work with:
Redraw the figure, label the given lengths and angles, and mark relationships that may not be obvious at first, such as parallel lines, right angles, or equal sides.
Before you calculate, see whether you can break the figure into simpler shapes or rearrange it into one you recognize.
For spatial problems, test cube nets, sketch different views of a solid, count faces and edges, or mentally rotate a shape.
For geometry areas that stood out in week 1, spend extra time rebuilding the basics before tackling harder contest questions.

By week 6, you’re ready for problems where the hardest part is figuring out how to organize the possibilities before you count them, including:
Systematic lists and casework
Complementary counting and basic probability
Permutations and combinations
Logical deduction
Your error log should tell you where to begin:
Missing the underlying idea? Start with a smaller version of the problem and organize the possibilities in a list, table, or tree diagram.
Choosing inefficient methods? Set up your cases before doing any arithmetic. With a clean structure, you can avoid counting the same outcome twice or missing one entirely.
Making calculation mistakes? Check your cases first. In counting problems, an answer that looks like an arithmetic slip can come from overlapping or missing possibilities.
During Mathnasium sessions, our tutors often ask students to walk through their steps so the students can make better sense of the concept. This aligns with research by Wong et al. (2002), which found that learners trained to self-explain performed better when applying what they had learned to new problems.
You put this into practice at home by explaining why your organizing method works out loud to yourself, a parent, a sibling, or a study buddy.

At this stage, start combining major AMC 8 skill areas, so you have to recognize the problem type and choose an approach for yourself. You can include number sense, geometry, counting, probability, graphs, and tables in the same sets.
As you read each question, look for clues like these that suggest a useful approach:
Rate problems may become clearer in a table
Geometry problems call for a diagram
Counting problems can be easier to organize with cases
Average problems may make more sense when you think in terms of totals
You may also try short strategy-sorting drills. Take 8–10 problems and sort them by likely strategy before solving them. You can also compare two possible approaches to the same problem and decide which one is faster or clearer.
Research by Rittle-Johnson and Star showed that seventh graders who compared different solution methods developed greater flexibility in choosing and using mathematical strategies than students who studied the methods separately.
The AMC 8 gives you about 1.6 minutes per question on average. That means you need to make quick decisions about when to keep working and when to come back later.
We suggest this pacing plan:
First 25 minutes: Work through the questions that feel manageable. Mark anything that is taking longer than about 2 minutes. Don’t let one hard problem steal the time you could use on two easier ones.
Next 10 minutes: Go back to the marked questions and give them a second look.
Final 5 minutes: Make sure every question has an answer. Since the AMC 8 does not penalize incorrect answers, leaving one blank guarantees you no credit for it.
Mathnasium tutors usually invite students to look back at how they solved a problem, not just whether they got it right. You can use the same idea after each timed set. Write down your score, then add two quick notes to your error log:
Which problem did I spend too long on before letting it go?
Which marked problem felt easier on the second pass, and what changed?
Those notes can help you spot patterns in your pacing. After a few simulations, you may notice that certain problem types deserve a first-pass attempt, while others are better saved for later.
Take your final full simulation early in the week under official conditions. That leaves the rest of the week for review rather than cramming.
You can review your simulation in three layers:
Correct answers: Was your method efficient, or did you get there the long way?
Incorrect answers: Was the miss a content, reading, approach, arithmetic, or pacing issue?
Unattempted questions: Was the obstacle recognizing the problem, confidence, or time?
Then create a personal trap list with your top five recurring errors and the specific fix for each. You can read it over before contest day.
Look through this checklist close to the contest week:
Confirm your site’s contest date within January 21–27.
Verify the location and when you need to arrive.
Check which materials your site allows.
Get a good night’s sleep the night before.
Go in with a calm two-pass plan.
The skills you build in this plan also carry into MATHCOUNTS, the national middle school math competition for grades 6–8. Chapter competitions take place in February, so students preparing for the AMC 8 are also building toward MATHCOUNTS.
Your math teacher or school coach can tell you when and where your chapter competes, or you can look it up with the MATHCOUNTS chapter competition search.
You can make your AMC 8 prep more effective with these free local support options:
Your school’s math team or club, where you can compare solution methods and talk through harder problems with classmates.
Ocee Library in Johns Creek has offered free math tutoring with high school volunteers. Check the Fulton County Library System for current sessions.
Gwinnett County Public Library, Duluth Branch, offers homework-help resources, and library cardholders can access Tutor.com. Check the current schedule.
A small study group: get a few classmates together, solve problems independently first, then compare approaches and discuss the main idea.
When the same mistakes keep coming back, or it’s hard to know what to work on next, structured support might help.
At Mathnasium, we begin with a diagnostic assessment to pinpoint each student’s specific math needs and goals, then create a personalized learning plan based on what we learn.
Students ready for more challenge may also enroll in the new Mathnasium Plus program at Mathnasium of North Johns Creek, where we help them develop deeper reasoning, multi-step problem-solving skills, and confidence with unfamiliar problems.
At Mathnasium of North Johns Creek, students work through challenging problems and explain their reasoning with guidance from specially trained tutors.
Mathnasium of North Johns Creek is a math-only learning center that helps PreK–12 students from Duluth, Johns Creek, and nearby communities excel in math.
To succeed in math class and in competitions such as the AMC 8 or MATHCOUNTS, students need more than to follow procedures. They need to recognize patterns, choose efficient strategies, work through unfamiliar problems, and learn from mistakes.
Those are the skills we aim to develop through math instruction guided by the Mathnasium Method™, our proprietary teaching approach.
Here’s how it works.
Each student begins with a diagnostic assessment that helps us understand their current skill level, knowledge gaps, goals, and how they think and feel about math.
Using those insights, we build a personalized learning plan focused on the skills they need most.
Our specially trained tutors follow the plan closely with live, face-to-face instruction in a caring and supportive group environment, in the center or online. They use mental, verbal, visual, tactile, and written techniques, so a tricky idea can make sense.
Students get room to think before tutors step in. Our tutors ask guiding questions instead of handing over answers, which builds the kind of critical thinking, problem-solving skills, and independence that competitions reward.
Fun is part of the approach, too. We use game-based activities, a reward system, and consistent encouragement to keep sessions engaging, even when the problems get hard.
The results speak for themselves:
94% of parents report an improvement in their child’s math skills and understanding
93% of parents report their child’s improved attitude toward math after attending Mathnasium
90% of students saw an improvement in their school grades
Whether your child is aiming for the AMC 8, working through math gaps, or simply ready for more challenge, a free diagnostic assessment is a great place to start. From there, we’ll create a personalized learning plan focused on the skills your student needs next.
