IELTS Vocabulary Study Plan: Work Backward From Your Test Date
Short answer: count the words you still need, count the days until your test, keep the last 5 to 7 days for revision only, and divide. Then protect time every day for review, because new words you never see again are mostly gone within a week. A plan that recalculates every day from "words left ÷ days left" survives missed days without you redoing the math.
Step 1: Decide what "the words" are
A plan needs a finite list. "Learn more vocabulary" never ends, so it is hard to tell if you are on track. For IELTS Academic, a sensible core is an academic word list: the few hundred to one thousand word families that appear again and again across university texts, such as significant, evidence, impact, policy or sustainable. You will meet these in Reading passages and need them in Writing Task 1 and Task 2. Pick one list and stick with it until the test. Mixing three lists makes the number feel bigger and the progress smaller.
Step 2: The words-per-day math
Use this formula:
new words per day = words you don't know yet ÷ (days until the test − revision days)
Some examples with a 950-word list:
- 90 days left, 6 revision days: 950 ÷ 84 ≈ 11–12 new words a day. Comfortable, with plenty of time for review and practice tests.
- 41 days left, 0 known words: 950 ÷ 41 ≈ 23 a day; keep 6 days for revision and it becomes 950 ÷ 35 ≈ 27. That is heavy. If you already know 200 of the words, it drops to 750 ÷ 35 ≈ 21.
- 20 days left: 950 ÷ 14 ≈ 68 a day, which is not realistic alongside other IELTS practice. Here it is better to cap new words at around 25 to 30 a day and accept that you will cover part of the list well rather than all of it badly.
The point of the cap is that every new word creates future review work. If you add 60 new words today, you will see many of them again tomorrow, in three days and in a week. Review load grows with every day you keep adding new words.
Step 3: Skip what you already know
Before you start, go through the list quickly and mark words you already know well enough to use in a sentence. Each one you remove lowers the daily number for the rest of your plan. Be honest: recognising allocate when you read it is not the same as using it in an essay. If you hesitate, keep it in the plan.
Step 4: Build review into the day
New words fade fast unless you meet them again at growing gaps. A common pattern is to review a word 1, 3, 7, 14, 30 and 60 days after you first learn it, and to bring back any word you got wrong the very next day. In practice, a day might look like this:
- Reviews first (10–15 minutes): words that are due today, including yesterday's misses.
- New words (10–20 minutes): today's quota, with the meaning, an example sentence and the pronunciation.
- A short quiz (5 minutes): test yourself on today's and recent words from different directions: meaning to word, word to meaning and fill-in-the-blank.
If you only have ten minutes on a busy day, do the reviews and skip the new words. Reviews protect what you have already invested; new words can wait a day.
Step 5: Use the last week for revision
In the final 5 to 7 days, stop adding new words. Go back over the words you missed most often and practise using topic words in Writing Task 2 sentences. That week is also when you will want time for full practice tests, so a vocabulary plan that is finished early takes pressure off.
Step 6: Re-plan, don't catch up
You will miss days. When that happens, do not try to do two days of new words at once. Recalculate: words left ÷ days left. The daily number goes up a little, spread over all remaining days, instead of one painful day. If it goes above your cap, accept covering slightly fewer words and keep the reviews going.
How Bandlio helps
Bandlio does this math for you. Enter your IELTS test date and it splits the words you have not learned yet over the days left, for example "D-41 · 18 words today"; without a date it uses 15 a day, and you can set a daily maximum. Its 950 words come from the New Academic Word List and are grouped into topics such as Environment, Education, Technology and Health. When you tap "I know it", a word comes back after 1, 3, 7, 14, 30 and 60 days; when you tap "Again", it comes back tomorrow. Ten-question quizzes send missed words back to review. Meanings are shown in easy English and in your language (24 built in, offline). No account; your progress stays on your phone. Bandlio cannot promise a band score; it helps you keep a steady vocabulary plan.
Frequently asked questions
How many words a day should I learn for IELTS?
Divide the words you still need by the study days you have left, after keeping the last few days for revision. With 950 words and 60 study days that is about 16 new words a day. Fewer than 10 a day is easy to keep up; more than 30 new words a day usually leaves too little time for review.
What if I miss a day?
Don't double up on new words the next day. Do your reviews first, then let the plan spread the missed words over the remaining days. A plan that recalculates from the words and days left handles this for you.
Is it too late to learn vocabulary two weeks before IELTS?
Two weeks is short for 950 new words, but not for the most useful part of them. Focus on reviewing words you already half know and on topic words you can use in Writing Task 2, and keep the daily number realistic.
