How long does it take to prepare for the TOEIC?

Every site answers "one to three months". That is true and useless, because the time you need depends on the gap you are closing, not on an average. Start instead from the one number ETS publishes that lets you reason at all: the standard error of difference is about 35 points per section.

Two different problems, two different calendars

Before building a schedule, work out which one you have. They do not take the same amount of time to fix.

A format problem

You understand English well enough, but you leak points on the mechanics: you discover that the audio never repeats, that Part 2 prints nothing at all, that Part 7 imposes a pace you cannot hold if you read everything. This kind of problem is fixed quickly — two to four weeks is often enough, and it is where the genuine hundred-points-in-a-month stories come from.

A level problem

You are blocked by vocabulary, speech rate or grammar. Here there is no shortcut: progress is slow and uneven, and ETS says as much in its own way when it notes that the test measures general proficiency rather than the content of any course. Count in months, not weeks.

Diagnose before you plan

Settling the question takes one sitting: do a full section, timed, without pausing and without going back. Then re-read your mistakes and sort them.

This reading only works if your practice reproduces the real constraints. A quiz you scroll at your own pace, replaying the audio, reveals no format problem at all — it hides every one of them.

A rhythm that works

On study habits there is no official data: what follows is common practice, not ETS guidance.

• About an hour a day is the most commonly recommended pace over four to twelve weeks. Below thirty minutes, progress becomes hard to measure inside a month.
• Regularity beats intensity. Five one-hour sessions beat one five-hour Sunday: consolidation needs the gaps between sessions.
• One full mock test a fortnight, no more. Two hours straight trains stamina, but a mock test teaches nothing on its own — the review is where the learning is.
• Half your time on review. Doing three hundred questions without re-reading them costs more time than doing a hundred and understanding every error.

Progress is not linear

Going from 700 to 800 is not the same work as going from 400 to 500. High on the scale, the remaining points live in the most discriminating questions — the ones with plausible distractors — and the room to manoeuvre shrinks. The limiting factor usually becomes speed rather than comprehension.

It is also why training changes character above 850: it stops being about learning and starts being about holding two hours without a dip in attention, at a reading pace that lets you finish Part 7.

When you are ready to book, how to register sets out the deadlines to count backwards from your own.
