Scores come from solving accurately — not from solving more.

A complete preparation strategy for the major standardized tests: realistic practice conditions, deep conceptual review, and test-taking strategy built to maximize scores.
We start by diagnosing exactly where your student stands.
*Credit By Exam — an exam for skipping ahead a course
*STAAR — Texas state assessment (grades 3–9)
It’s not too late — but the fundamentals have to be seen clearly first.
Top students have been building their fundamentals for five to ten years. Trying to win a short sprint on a weak foundation is closer to wishful thinking.
So YEON starts by reading the student’s fundamentals. Only when you know exactly where a student stands can you see what’s actually achievable in the time that remains.
Across private and public education, college admissions, careers, and business — in both Korea and the US — one thing has held true: opportunity is given to those who can take it on. Being “late” is never a reason to give up.
Stop just solving problems. Analyze the types, then attack strategically.
Master the core concepts first, then prepare by problem type — it is the most effective path.
Type analysis & strategy
Instead of grinding endless practice sets, we analyze each problem type and approach it strategically.
→ Efficient time use, fewer wrong answers
Personalized error notes
The task students avoid most, but the most accurate and transparent. There is a clear link between error-note completion and scores.
→ Pinpoints each student’s strengths and weaknesses
Applied practice quizzes
To read a passage you need a wide vocabulary — including the nuances and applications of each word — to grasp context precisely.
→ Learning by understanding, not memorization
Practical high-difficulty problems
We prepare fully for the hardest problems. Approached with the right purpose, even unfamiliar questions become answerable.
→ Stable readiness for the toughest tests
You study with materials and a platform YEON built.
In-house learning materials
We use materials YEON created — every problem type strategy and essential concept included.
→ Type strategies + essential concepts
A purpose-built testing platform
Mock exams run on a platform we developed: time per question, high-error types, and more analyzed from every angle.
→ A test experience that mirrors the real thing
Students take the test alone — but they prepare with us.
Dedicated management chat
Ask anytime and get a reply within one to two hours. Across 300+ students, one truth is clear: the students who communicate with us most reach their goals.
Regular progress reports
Before every parent meeting, we report class attitude, assignment completion, and recommendations in detail.
Regular parent consultations
Throughout the program we review the student’s status, direction, and overall performance together with parents.
A curriculum that accounts for the student’s psychology and thinking.
Most programs
The student carries 95% of the load alone
YEON
Our curriculum is engineered to carry 25% for the student
A good curriculum carries 25% of the load for the student. Not spoon-feeding answers — designing things so a student goes further with less force. That’s why we’re confident.

“My child only ever solved problems. As the test neared, they came to see how much error notes and type analysis matter. In the end they reached their target SAT® score — such a relief.”
11th-grade parent
“Being able to ask about problems instantly over 1:1 chat was the best part. They pinpointed exactly what I was missing, and testing on the platform meant I was far less nervous on the real day.”
AP® exam student
Getting started is simple — three steps.
Parent consultation
We understand the student’s academic level, current situation, and goals.
Diagnostic mock exam
We examine the student’s ability area by area in detail.
Program recommendation
Combining the consultation and test results, we propose the solution that fits best.
Frequently asked questions
First, confirm where your student actually stands.
Time spent solving problems without knowing what’s missing is the most expensive waste of all. We pinpoint the student’s position with a parent consultation and a mock exam, then propose the best-fitting solution.
