AIME Math Coaching
Pristone Academy helps students prepare for AIME-style work through live, online, one-on-one coaching. The student solves and explains; Edward observes approach selection, depth, arithmetic control, and verification. The result is targeted training across advanced algebra, number theory, geometry, and combinatorics—not simply a larger pile of hard problems.
Premium private coaching, typically structured as multi-session engagements.
AIME readiness work is a premium, high-touch service delivered live online. The paid diagnostic is billed hourly, with the exact rate confirmed before scheduling; it identifies whether the first priority is content depth, precision, problem selection, or verification discipline.

Free readiness check
Check the AMC base before pushing into AIME depth.
The AMC 10 readiness check gives a quick read on recognition, pacing, accuracy, and contest maturity before deeper AIME work.
Who this is for
Students who have qualified for AIME, are close to qualifying, or are training seriously beyond standard AMC 10/12 material. The work is best for students ready to slow down, explain their reasoning, and build accuracy under pressure.
- Students moving from AMC multiple-choice habits into integer-answer work
- Students who can start hard problems but lose points to execution or verification
- Families who want an honest readiness read before committing to intensive prep
- Advanced students building long-term olympiad-style mathematical maturity
What you walk away with
- ✓A clear AIME readiness profile
- ✓A prioritized plan across depth, execution, and verification
- ✓Stronger habits for choosing methods and checking answers
- ✓Parent-facing clarity about what is realistic in the current timeline
Who this is not for
Being upfront about fit saves everyone time — including yours. This program is not a good match if:
- Students looking for shortcuts without sustained practice
- Families expecting promised qualification or score outcomes
- Students seeking answer keys or completed solutions without sustained practice

How the AIME track works
1
Readiness diagnostic
Before or during the first live session, we observe how the student handles non-multiple-choice problems, not just whether they have seen the topic before.
2
Depth modules
Training moves through advanced algebra, number theory, combinatorics, and geometry at the level the student can productively absorb.
3
Precision protocol
AIME rewards clean execution. Students practice bounding, second-method checks, small-case tests, and answer-format discipline.
4
Retest and report
New mixed work tests whether the repair transfers. When useful, parents receive a structured summary of strengths, gaps, readiness, and next steps.
Measure readiness before prescribing harder work.
A live diagnostic separates content depth from method selection, execution, and verification so the next training block has a clear purpose.
Frequently asked questions
Yes. Sessions are live online and private. Visible scratch work and explanation make it possible to coach the student's method, precision, and verification process rather than only check an integer answer.
Edward reviews recent AMC or AIME-style work and observes the student solving representative problems. The deliverable is a ranked readiness profile and a first repair plan grounded in the work shown.
No. Some students are current qualifiers; others are AMC students trying to understand whether AIME readiness is a realistic near-term target.
No. Pristone does not promise specific scores, cutoffs, or qualification outcomes. The value is an honest diagnosis and serious training.
AMC 10 coaching emphasizes broad recognition, pacing, and multiple-choice strategy. AIME coaching emphasizes depth, integer-answer precision, verification, and longer solution paths.
There is no responsible fixed answer before the diagnostic. The student's current depth, timeline, goals, and transfer on new work determine the initial cadence and whether it should change.
