The SAT is a solvable problem.
Most students don't lack ability — they lack a system. I diagnose exactly where points are leaking, then coach your student through it, one session at a time, until the score follows.
Every lost point has a reason.
Find the pattern, fix the habit, watch the score follow. That's the whole job.
How a score actually moves.
No generic worksheets. Every student follows the same four-step loop — built around their gaps, not a one-size template.
Diagnose
A full timed practice test, then a question-by-question breakdown of exactly where points are lost — content, timing, or careless errors.
Plan
A targeted study map. We attack the highest-yield weaknesses first, so early sessions produce the biggest score jumps.
Drill
Focused 1-on-1 sessions on the real patterns the test reuses — with homework that reinforces each concept between meetings.
Prove
Regular re-tests track the climb. We adjust the plan as the numbers move, all the way to test day.
Other programs.
The SAT is the specialty — not the limit. With a perfect TOEIC and a shelf of math-competition titles, I also coach:

English & Writing
Reading, grammar, and essay writing, plus TOEIC/TOEFL prep — grounded in a perfect 990 TOEIC.
Custom requests
A different goal — an AP subject, a school course, interview prep? Ask, and we'll see if it's a fit.

Andrew Cho
Andrew Cho is a 1-on-1 SAT instructor who scored where his students want to be — a perfect 800 on SAT Math, a 1520 composite, and a perfect 990 on the TOEIC. That combination means he has mastered both the mathematical reasoning and the English fluency the exam demands, and he knows exactly how the test thinks.
His coaching rests on one conviction: the SAT rewards preparation, not luck. Most students lose points to a small set of repeatable patterns — a timing habit, a recurring question type, a careless step — and once those are found and fixed, the score climbs. Instead of generic worksheets, Andrew pinpoints each student's specific leaks and coaches them out, one session at a time.

Do you tutor online, in person, or both?
Both. In-person sessions run in Seoul; remote sessions run over video for students anywhere in the world, at any time — I keep a 24/7 schedule across time zones.
How far in advance should we start?
The earlier the better. Most students see the biggest gains with two to three months of consistent sessions before test day — enough time to diagnose, drill the weak spots, and re-test. Focused work helps even on a shorter runway, and we'll map a realistic plan to your date on the first call.
What does it cost?
Pricing is per session at a clear, standard rate, shared on the consultation call once we've agreed on a plan.
