Key facts

Time to a levelNIIED publishes no figure. Yonsei KLI: one level per 10-week term (200 class hours), roughly aligned with TOPIK 1 to 6 [1]
How hard is Korean?The US Foreign Service Institute puts Korean in its hardest group for English speakers: about 88 weeks or 2,200 class hours to professional working proficiency [2]
Vocabulary at level 1About 800 basic words (NIIED level descriptor) [3]
Vocabulary at level 2About 1,500 to 2,000 words (NIIED level descriptor) [3]
Cut-offs to aim forTOPIK I: 80 (level 1), 140 (level 2) of 200. TOPIK II: 120, 150, 190, 230 (levels 3 to 6) of 300 [5]

How long does it take to reach a TOPIK level?

No agency publishes a figure for this, and any number you see is an estimate. The closest reference points are university language programs: Yonsei's Korean Language Institute spends 200 class hours on each of its six levels, and those levels are designed to line up roughly with TOPIK levels 1 to 6.

Yonsei notes that the mapping is approximate and does not guarantee a TOPIK score; its table puts institute level 3 between TOPIK 2 and 4, and levels 4 to 6 at about TOPIK 4 to 6. Read it as roughly 200 hours of classroom work per level for a full-time student, with self-study on top.

For English speakers, the US Foreign Service Institute puts Korean in its hardest group, at about 88 weeks or 2,200 class hours to professional working proficiency. Time depends on your starting point, your hours per week and how much of that time is active practice. The routines below assume you study most days.

What does each level expect from you?

NIIED's level descriptors tell you what to practice: everyday survival topics and about 800 words at level 1, paragraph-level texts and 1,500 to 2,000 words at level 2, social topics at level 3, easy news and idioms at level 4, and unfamiliar political, economic and cultural topics at levels 5 and 6.

Use the descriptor for the level above your current one as your reading and listening syllabus: at level 1 and 2, everyday notices, dialogues and about 800 to 2,000 words; at level 3 and 4, news-style texts, idioms and Sino-Korean vocabulary; at level 5 and 6, editorials and academic texts on unfamiliar topics. The full descriptors are in the levels and scores guide.

Which test should you register for?

Register for TOPIK I if your goal is level 1 or 2, and for TOPIK II if your goal is level 3 or higher. You cannot get a level 3 from TOPIK I, and a TOPIK II score under 120 gives no level at all.

If you are between the two, timed practice tells you more than a feeling: score a TOPIK II listening and reading set under real time limits, and if you are consistently near 120 of 300 with writing still to add, TOPIK II is realistic. The two tests run in the morning and afternoon of the same day, so where a site offers both you can register for both. See the exam format guide and the 2026 dates.

What should a weekly routine look like?

Split your week across vocabulary, listening, reading and (for TOPIK II) writing, and do one timed set every week. The hours below are suggestions for someone studying most days; they are not a promise of a result.

Suggested weekly routine by target (hours are illustrative)
TargetVocabulary and grammarListeningReadingWritingTimed practice
Level 1 to 2 (TOPIK I)3 to 4 h: 15 to 25 new words a day with flashcards, one grammar point a day2 h: short dialogues, replayed until every line is clear2 h: signs, notices, short paragraphsNot tested; write new words in short sentencesOne 100-minute TOPIK I set every 1 to 2 weeks
Level 3 to 4 (TOPIK II)3 to 4 h: 20 to 30 words a day incl. Sino-Korean roots, two grammar points3 h: news clips, announcements, short lectures3 h: 2 to 3 passages a day, timed2 h: one question 51 to 53 set and one question 54 essay a weekOne full 180-minute TOPIK II set every 2 weeks
Level 5 to 6 (TOPIK II)3 h: abstract and academic vocabulary from your own reading3 h: discussions, documentaries, lectures at natural speed4 h: editorials and academic texts, 50 items in 70 minutes3 h: two question 54 essays a week, checked against the criteriaOne full TOPIK II set every week in the last two months

Adjust the split to your weakest section. The level depends on the total score only, so a strong section can carry a weaker one, but every section is worth 100 points. Review your wrong answers before you add new material.

How should you practice writing for TOPIK II?

Write in the formal written -다 style, keep to the character ranges (200 to 300 for question 53, 600 to 700 for question 54), answer every sub-question in the prompt, and practice on a 원고지 grid so the paper format holds no surprises.

NIIED's answer guide marks questions 53 and 54 on content and task performance, organization, and language use, with language use counted twice, so the same idea in more accurate, higher-level Korean scores more. Rewrite your own essays once with better connectives and vocabulary rather than only writing new ones. Rubric bands, grid rules and style rules are in the writing guide.

What should you do in the last two weeks?

Switch from learning to rehearsing: full sets under real timing, a fixed sleep schedule around the test time, and a check of the practical rules so nothing on the day surprises you.

  • Do at least two full sets under real conditions: 100 minutes for TOPIK I, 180 minutes with the break for TOPIK II, answers on a printed sheet.
  • Practice the answer sheet: one circle per item, writing inside the box. Two marks or a partial mark scores 0, and text outside the box earns no points.
  • Read your admission ticket for the check-in time; times differ by country and year, and late arrivals cannot enter. Bring a valid original ID and correction tape.
  • Hand in every electronic device before the first session. A device with AI translation or writing functions voids the test and bars you for two years.
  • Stop cramming new vocabulary in the last two days; reread your wrong-answer notes instead.

How does TopikIQ fit into this routine?

TopikIQ covers the daily practice part: TOPIK-style reading, listening and writing questions at your level with an explanation in your language, flashcards for vocabulary, and a wrong-answer notebook for review.

The free plan gives 20 questions a day in sessions of 10, 3,000+ vocabulary flashcards with spaced repetition, 44 grammar points, mistake review and 3 AI tutor chats a day; a signed-in free account can also try one full mock exam and one AI writing feedback. After 20 answers in each scored section the app shows an estimated score, which is an estimate, not an official result. The questions are original, not past exam papers, and TopikIQ is not affiliated with NIIED.
