16 Days Until the BJT — Is It Too Late? A Two-Week Sprint Plan

Short answer: no, it's not too late — as long as you spend these 16 days on exam calibration, not "studying."

Sixteen days can't rebuild your vocabulary or grammar foundation. But they are exactly enough to fix four things: question-type reflexes, time management, listening rhythm, and habitual point-loss — and the BJT takes a surprising share of its points from precisely these four.

First, be clear: what 16 days can and cannot change

Cannot change: total vocabulary, grammar system. Cramming a word list now has the worst return in the room.

Can change: your reflexes for each question type, per-question time budget, a strategy for the long listening passages, and those "I knew this but got it wrong again" habits. Between J2 (420–529) and J1 (530–599) often sit exactly those few dozen habit points.

Days 1–2: Find out where you stand

Start with one full mock exam (80 questions) — no dictionary, no replays, strictly timed. Record three numbers: overall accuracy, accuracy for each of the three sections — Listening (choukai / 聴解), Listening & Reading (chou-dokkai / 聴読解), Reading (dokkai / 読解) — and your weakest question type. The goal of these two days isn't to score higher; it's to draw your weakness map. The next 14 days follow that map.

Days 3–10: Attack only your weakest section

A fixed daily quota (30 questions minimum for a full-time worker), all aimed at the weak section. Handle every mistake with three questions: Why was it wrong? What was it testing — a word, grammar, or the relationship between speakers? Would I still recognize it in a different scene? The questions you can't answer all three for are the only ones worth your time.

For "listening fatigue" there is one cure: stop trying to catch every word. Catch two things instead — who is speaking to whom (the relationship), and which way the attitude is leaning (agreeing, politely declining, requesting). On BJT listening questions, far more answers are missed on relationship judgment than on vocabulary.

Days 11–14: Full papers at exam rhythm

One full paper every other day; on the days between, review mistakes only — no new questions. The core skill here is the courage to let go: stuck for more than 30 seconds, pick something and move on. In a CBT exam, every second spent on one question is deducted from the questions behind it.

Days 15–16: No new questions

Only your mistake notebook and business-scene expressions. Shift your sleep schedule to match the exam slot so your brain learns to switch into Japanese at that hour. ID, route, arrival time — all prepared the night before. New questions in the last two days manufacture anxiety, not points.

How long per day for 16 days?

For a working adult, 1–1.5 hours is enough. What matters isn't the daily length — it's 16 days without a single break. Miss one day and the rhythm has to be rebuilt.

Should I cram vocabulary?

Not from a word book. Collect only one kind of word: the ones that appeared in your mistakes. They're proven to be tested, and proven to be words you don't know — the only list worth memorizing in 16 days.

How close is my mock score to the real one?

It varies — don't obsess over the absolute number. Watch the trend: under the same conditions, if your accuracy climbs from 60% to 80%, the real score moves with it.

If you're exactly the "a couple of weeks left" person, the system has short-cycle plans built for you (3-day and 10-day sprints). Check where you stand first, then decide how to spend your 16 days.

Your field, your plow.
