One flight to Korea.
All that's left is a passing score.

Seoul's EPS-TOPIK picks only the spots where you actually get stuck — Cause / Reason grammar — so 10 minutes a day is enough.

01 — Problem

The road to passing
is far too long.

01

Thick textbooks

You don't know where to start, and you stay stuck on the same parts forever.

02

Expensive local classes

Hundreds of dollars a month — and rarely explained in your own language.

03

Studying alone has limits

You can't tell which question types you're weak at, or how much you've improved.

02 Why it works

The opposite of
"just do more questions".

Seoul's EPS-TOPIK competes on precision, not volume. Every item is tagged with

concept_group skill_tag difficulty_score

— combined with your error pattern to pick the single most efficient next question.

🔍
01

We see the cause, not the category

↗

Not just 'weak at RC' — we drill down to 'weak at cause/reason grammar'. Tracked per skill_tag.

🎯
02

Only your weak spots

↗

A wrong-answer weighting algorithm re-serves your hardest topics at easier difficulty first.

⚡
03

One action at a time

↗

Today's task is one card. Not '78 items to review' — just '10 minutes and you're done'.

🧠
04

Review right before you forget

↗

3 days → 7 → 14 → 30. SRS spacing locks vocabulary into long-term memory.

03 How it works

First minute → today's 10 minutes → exam day.
