Study 15 new words a day for 90 days and you land at 1,350 words — enough to cover the entire beginner vocabulary list (982 words) plus a meaningful head start on intermediate words. If your target is Level 4, which requires a cumulative 3,093 words, the daily count jumps to about 35 words a day. The number of words matters less than how you study them: this plan assumes you're cycling back through vocabulary you've already seen, not just plowing forward once.
| Target | Cumulative | Words/day (90d) |
|---|---|---|
| Beginner (TOPIK Level 1–2) | 982 | 11 |
| Intermediate (TOPIK Level 3–4) | 3093 | 35 |
| Advanced (TOPIK Level 5–6) | 5965 | 67 |
The baseline plan is straightforward: 15 new words a day, every day, for 90 days. Multiply that out and you get 1,350 words — a number that lines up almost exactly with the entire beginner-level list (982 words), with room left over to start working through intermediate vocabulary. For most learners aiming at the beginner levels, or building a solid foundation before jumping into intermediate study, this is a realistic, sustainable pace.
If your goal is Level 4, the math changes. Level 4 requires a cumulative 3,093 words, which means fitting that vocabulary into the same 90-day window pushes your daily target up to roughly 35 words a day. That's more than double the baseline pace, and it's worth being honest with yourself about whether that's sustainable alongside everything else you're studying — grammar, listening, writing. Some learners choose to stretch the Level 4 vocabulary goal beyond 3 months rather than more than double their daily load.
Either way, the daily word count you pick should assume you're not just seeing each word once and moving on. This plan works because it's built around cycling back through words you've already studied — which is exactly what the next section covers.
When you learn a word for the first time, it doesn't stay put in memory — it fades, often within days, unless something brings it back. That's the basic problem with a purely linear study plan: you learn 15 new words today, 15 more tomorrow, and by the time you've moved on to word 200, word 5 is already slipping away. A repetition-cycle (회독) approach solves this by design: instead of only moving forward, you deliberately loop back through words you've already met.
The difference isn't just psychological comfort — it changes what you're actually training. On a first pass, you're mostly building recognition: you see a word and a definition together and it feels familiar. On a second or third pass, especially after some time has gone by, you're training recall — pulling the word up from memory without the answer sitting right next to it. That's the skill the actual exam tests, so it's the skill worth practicing.
In practice, this means your daily 15 (or 35) words are never just new words in isolation. Some of that study time goes to fresh vocabulary, and some goes back to words from earlier days or earlier weeks. The exact mix will vary by learner, but the principle stays the same: new exposure plus repeated review beats new exposure alone.
Picture a week built around the 15-words-a-day baseline. Each day still delivers its 15 new words, but part of that daily study session is spent circling back to vocabulary from earlier in the week or earlier cycles, rather than treating every day as a fresh, isolated batch. By the end of the week, you've added over 100 new words, and — just as importantly — you've touched most of those words more than once instead of only once.
The same structure scales up for the Level 4 pace. At roughly 35 words a day, a week adds up to a much larger new-word count, so the review portion of each session becomes even more important — without it, you're adding words faster than you can realistically retain them. Whichever pace you're on, the weekly rhythm is the same: new words plus a return visit to recent ones, repeated week after week until you reach the 90-day mark.
By the time you hit the last two weeks of the 90-day plan, the priority should shift. Instead of pushing hard on brand-new vocabulary, spend most of your time on the words that have already given you trouble — the ones you've gotten wrong more than once, mixed up with a similar-sounding word, or simply never felt confident about. Keeping a running list of these as you go through the earlier weeks makes this phase much easier, since you'll walk into the final stretch with a ready-made review set instead of having to reconstruct it from memory.
Alongside your error list, weight your remaining review time toward the vocabulary that shows up most often, rather than treating every word on your list as equally important. Not every word you've studied over the past weeks carries equal weight on the actual exam, and in a tight two-week window, your time is better spent making sure high-frequency words are locked in than squeezing in a handful of rarely-used ones. The goal for these final two weeks isn't volume — it's making sure the words you're most likely to actually need are ones you can recall without hesitation.
You need to review. Moving forward without cycling back is the main reason vocabulary plans fail — words fade from memory within days if you don't revisit them, so build review time into every study session rather than treating it as optional.
Slow down your new-word intake before you cut review time. It's better to add fewer new words each day and keep cycling through what you've already learned than to keep pace on new words while skipping review — half-learned vocabulary you never revisit isn't worth much on exam day.
Start with beginner vocabulary and let intermediate words follow naturally as your daily count builds up. At 15 words a day, you'll cover the full beginner list before you're deep into intermediate territory, which gives you a solid foundation before the harder words show up.
It depends on which level you're targeting — 1,350 words comfortably covers beginner vocabulary and a start on intermediate, while a Level 4 goal requires a much larger cumulative total (3,093 words).
