What each level means in practice
Level 1: basic survival Korean — greetings, shopping, ordering food (~800 words).
Level 2: daily conversations and simple public information (~1,500–2,000 words).
Level 3: daily life plus familiar social topics; enough for most F-visa point requirements.
Level 4: news and ordinary work tasks; a common minimum for university admission.
Level 5: professional research or work contexts.
Level 6: near-native fluency in academic and professional settings; required for medicine and some government scholarships.
Level 1 is survival: greetings, ordering, buying a ticket, roughly 800 words. Level 2 handles everyday routine — the post office, a doctor's appointment, arranging to meet someone — with formal and informal speech kept apart.
Level 3 is where Korean becomes usable rather than merely present. A Level 3 speaker manages ordinary social and workplace situations and reads straightforward factual text. Level 4 adds abstraction: news, general current affairs, the ability to follow an argument, and enough written register to produce a report. This is the level most universities and most employers actually mean when they say they want Korean.
Level 5 handles specialised material in a familiar professional field and unfamiliar topics with some effort. Level 6 is functional near-fluency: research, negotiation, argument at length. It does not claim native ability, and the exam does not test speaking at all.
On the paper exam, TOPIK I gives Level 1 from 80 out of 200 and Level 2 from 140. TOPIK II gives Level 3 from 120 out of 300, Level 4 from 150, Level 5 from 190 and Level 6 from 230.
Notice the spacing. The step from Level 3 to Level 4 is 30 marks, the same as from 4 to 5, but the step from 5 to 6 is 40. The last level is deliberately the expensive one.
Under 80 on TOPIK I there is no level at all. The result is recorded as unclassified rather than as a failure, and the certificate simply is not issued. There is no penalty attached to it beyond the fee and the day.
Aim at the requirement, not at the highest number you could imagine reaching. Undergraduate admission generally asks Level 3, graduation Level 4, graduate programmes Level 4 or 5 depending on the department, and scholarship applications reward each level with points rather than a simple pass.
One more practical note: a TOPIK certificate is valid for two years from the announcement of the result. Sitting the exam three years before you need it is sitting it twice.
Honest ranges, for someone studying consistently: zero to Level 2 in roughly six months, Level 2 to Level 3 in another six, Level 3 to Level 4 in six to twelve. Level 4 to Level 6 is where the timeline stops being predictable, because it depends less on study hours and more on how much real Korean you read and hear outside a textbook.
The plateau almost everyone hits is between 4 and 5. It is not a vocabulary problem. It is that the exam stops asking what a passage says and starts asking what the writer thinks about it.
