Most IELTS preparation fails for a boring reason. The candidate spreads their effort evenly across four modules when only one of them is holding the overall band down. Your overall score is the average of the four, rounded, so an hour spent on the skill you are already good at moves the number barely at all, and an hour spent on your weakest one can move it by half a band.
So the order below is not four equal steps. It is a diagnosis, then one repair at a time, cheapest repair first.
This guide assumes you already know how the test is built. If you have never sat it and still need the format, the scoring system and how registration works, start with IELTS preparation for complete beginners and come back here once you have a date booked.
#Step 1: Measure the baseline before you buy anything
You cannot prioritise what you have not measured, and self-marking does not work. The two productive skills are the problem: you can mark your own reading against an answer key, but nobody can mark their own essay accurately, because the errors you can see are the ones you have already stopped making.
What a baseline needs to tell you is not one overall number. It is four numbers, so you can see which one is dragging. A candidate at 7.5, 7.5, 7.0 and 5.5 does not have a 7.0 problem. They have a 5.5 problem, and everything else is already clear of most university requirements.
Take the measurement under real timing. Academic Reading is 60 minutes for 40 questions across three passages, Listening is 30 minutes plus transfer time, and Task 2 is 40 of your 60 writing minutes. A band produced without the clock running is not the band you will get.
The free diagnostic gives you a band across all four modules without an account. If you only want the writing number, the IELTS writing checker marks a Task 1 or Task 2 answer against the four official criteria and shows the sentences costing you marks.
#Step 2: Fix the structural errors in writing first
Writing is usually the lowest of the four, and it is the one that improves least from reading about it. The reason is that the marks are lost in patterns you repeat, and a pattern is invisible from the inside until something points at it.
The four criteria carry equal weight, which is the fact most candidates get wrong. People pour their effort into vocabulary, which is one quarter of the mark, while losing a whole band on Task Response because the second body paragraph drifts off the question. Our breakdown of what the four writing criteria actually mean goes through each one at bands 6, 7 and 8.
Work in this order, because it matches where marks are usually lost:
- Task Response. Answer every part of the prompt. A two part question answered once caps you, however well written the half you did answer.
- Coherence and Cohesion. One idea per paragraph, and linking words only where the logic actually turns. Writing "Furthermore" every second sentence costs marks rather than earning them.
- Lexical Resource. Precision beats rarity. A common word used exactly is worth more than an unusual one used approximately.
- Grammatical Range and Accuracy. Fix the repeated slip first. Most candidates have two or three recurring errors doing most of the damage.
The practical method is narrow. Write one answer, get it marked, fix the single highest cost error, and write another. Repeating an essay with the same error in it just practises the error. There are 69 Task 2 questions and 69 Task 1 questions here, each with a model answer, if you need prompts.
How many that takes is the question everyone asks next, and the honest answer is that the count matters less than whether each one was marked before you wrote the following one. How many practice essays you should write works through what the number depends on.
#Step 3: Build speaking rhythm by speaking, not by planning
Speaking is the module where preparation most often makes things worse. Memorised answers are audible, and they cost you under Fluency and Coherence when the examiner moves off the script you prepared for.
What actually moves the band is continuous speech under mild pressure. Part 2 gives you one minute to prepare and up to two minutes to talk, and most candidates stop at about seventy seconds because they run out of planned material rather than language. The fix is to practise extending: one more example, one more reason, one more comparison.
Record yourself and listen back. It is uncomfortable and it is the fastest diagnostic you have, because filler words and self correction are obvious on playback and invisible while you are talking. If your accent is the thing you are worried about, it is worth reading what the criteria actually say: pronunciation is marked on whether you can be understood, not on sounding like any particular country.
There are 40 Part 2 cue cards with their Part 3 follow ups on the speaking cue cards page, and the speaking practice tool gives you a band with feedback on fluency.
#Step 4: Drill reading and listening against real passages
Reading and listening are pattern recognition, and they respond to volume in a way writing does not. The catch is that volume only helps if you review properly.
Never stop at right or wrong. For every question you missed, go back into the passage or the transcript and find the exact sentence that proves the correct answer. That sentence is the pattern. Do this for fifty questions and you start seeing the traps before you fall into them, which is the entire skill.
True, False, Not Given is where most reading marks are lost, and almost always in the same direction: candidates pick False for something the passage simply does not mention. False means the passage contradicts it. Not Given means the passage is silent. The True, False, Not Given guide works through the distinction with examples.
For volume, there are 81 complete reading tests published in full, free and with no signup, and every answer carries a written explanation rather than a bare key. Listening practice sits on the listening practice page with notes on the traps.
#Does IELTS preparation need a paid course?
For most candidates, no. A course buys you structure and a deadline, which is worth real money if you will not otherwise sit down and work. What it does not buy you is the thing that actually moves the band, which is a marked answer with the specific error pointed at, often enough to break the habit.
The parts of preparation that genuinely cost money are marking and speaking time, because both need a second party. Everything else is format knowledge and volume, and both are free. A course is worth it if your weakest module is speaking and you have nobody to talk to. It is usually not worth it if your weakest module is reading, where the fix is doing passages and reviewing them properly.
Whatever you use, ask it one question before you trust a number it gives you: does it tell you how its scoring was measured? We re-measure ours every week and publish the result including the weeks it gets worse, with the method and the limits, at our scoring quality page. The reference bands there are labelled in house against the public band descriptors, which that page states plainly.
#How long this takes
It depends entirely on the gap. Half a band in one module is usually a few weeks of focused work. Two bands across all four is months, and anyone promising otherwise is selling something. If you have a fixed date and about a month, the 30 day study plan lays the same priorities out as a day by day calendar.
The one thing that reliably wastes time is studying evenly. Measure first, find the module that is actually costing you the overall band, and spend your effort there until it stops being the weakest one.
