AMC 10 Math Coaching
Pristone Academy helps ambitious students prepare for the AMC 10 through live, online, one-on-one coaching. The student solves and explains while Edward observes recognition, strategy, scratch work, pacing, and verification. That evidence becomes a focused plan across algebra, number theory, counting, geometry, and contest decisions.
Premium private coaching, typically structured as multi-session engagements.
This is premium live 1:1 coaching. The paid diagnostic is billed hourly, with the exact rate confirmed before scheduling; it establishes the initial scope and recommended cadence before any longer engagement.

Not sure where your student stands?
Answer nine quick questions and get a deterministic AMC 10 readiness band with two strengths and two priority gaps.
Who this is for
Students who are strong in school math but need a more strategic, contest-specific way to approach AMC 10 problems. The work is especially useful when a student is practicing hard but still losing points to timing, recognition, or avoidable errors.
- Students preparing seriously for the AMC 10A or AMC 10B
- Families who want a clear read on readiness before adding more practice
- Students who need strategy, pacing, and problem selection, not just solutions
- Advanced middle-school or high-school students building toward AIME readiness
What you walk away with
- ✓A clear map of strengths, gaps, and readiness level
- ✓A prioritized practice plan across the main AMC 10 topic families
- ✓Better decisions about when to solve, skip, estimate, or return
- ✓Parent-facing clarity about what is improving and what still needs work
Who this is not for
Being upfront about fit saves everyone time — including yours. This program is not a good match if:
- Families looking for a bulk homework-help service
- Students who only want answers without doing structured practice
- Families expecting guaranteed AIME qualification, scores, or admissions outcomes
- Students seeking routine school homework completion rather than contest training

How the AMC 10 track works
1
Observe a representative set
Before or during the first live session, the student works a representative set so we can observe how they read, choose, time, and verify problems across the AMC 10 pillars.
2
Explain the diagnostic
The student and parent receive a plain-language account of strengths, priority gaps, readiness, and the evidence behind the initial plan.
3
Repair the highest-value gap
Live instruction combines topic repair with pacing, expected-value choices, skip discipline, and review habits that matter under the 75-minute format.
4
Retest in mixed work
New mixed and timed work tests whether the repair transfers. The plan changes when the student's evidence changes.
Diagnostic map
What the AMC 10 diagnostic separates
Knowledge gaps
Missing or unstable tools in algebra, geometry, number theory, counting, probability, or arithmetic fluency.
Recognition gaps
Knowing a method once it is named but not recognizing the structure when the contest removes the chapter label.
Execution gaps
Misreading constraints, arithmetic slips, incomplete verification, or scratch work that becomes hard to audit under time pressure.
Strategy gaps
Problem selection, pacing, skip-and-return decisions, and whether guesses are informed by actual elimination.
Turn a score into a useful diagnosis.
A diagnostic session looks beyond the total to identify whether content, recognition, execution, or contest strategy is the current bottleneck.
Frequently asked questions
Yes. Coaching is live online and private. The student works visibly and explains decisions so feedback can address recognition, method choice, scratch work, pacing, and verification—not just the final answer.
Edward reviews recent contest work and observes the student solving representative problems. The result is a ranked readiness profile and a first repair plan, not a generic list of every AMC topic.
Bring recent AMC-style work or a practice result if available, plus a rough timeline and goal. Names of schools, student records, and other unrelated personal information are not needed for the academic diagnosis.
Both can fit if the student is serious. The diagnostic determines whether the work should begin with foundations, contest strategy, topic depth, or readiness for harder problem sets.
No. AIME qualification depends on the student, timeline, exam difficulty, and execution under pressure. The goal is to give an honest readiness read and train the gaps that matter.
Yes. For diagnostic sessions, Pristone can produce a parent-facing summary that explains strengths, priority gaps, readiness, and next steps in plain language.
The answer depends on the starting profile, timeline, goals, and how quickly repairs transfer to new timed work. The diagnostic establishes the initial scope; progress evidence determines whether the cadence should continue or change.
Regular tutoring often follows a school unit or homework set. AMC 10 coaching adds recognition without chapter labels, problem selection, time allocation, no-calculator execution, and deliberate verification under contest conditions.
