Reality Check Before You Start

Thirty days can move you up by roughly 0.5 to 1 band if you work consistently. That is a realistic figure, not a promise.

If your current level is Band 5.5 and your target is Band 7, thirty days will not get you there. You will need three to six months. If you are at 6.5 and need 7, thirty days of focused work is very possible.

So before anything else, find out your starting point. Do not guess.

Take a full diagnostic test before Day 1. Use a Cambridge IELTS book, sit the Listening and Reading sections with a timer, and write both Writing tasks. If you can afford it, pay a teacher to mark your writing. If not, compare your essays against the public band descriptors and be harsh with yourself.

Write down two numbers: your current estimated band, and your target band. Stick them on your wall. Everything you do for the next month should be aimed at closing that gap.

Before Day 1: Three Things to Sort Out

1. Book your test now, not later. Test slots at the British Council and IDP centres in Dhaka, Chattogram, Sylhet, and Khulna fill up quickly, especially before the January and September intakes. If you are preparing for a visa deadline, book first and prepare second. The deadline will keep you honest.

2. Confirm your test type. Academic or General Training. If you are unsure, stop and confirm with the university, employer, or immigration authority. Do not book on a guess.

3. Gather your materials. You do not need much:

That is enough. You do not need twelve books, five apps, and a coaching centre unless you genuinely need the structure.

The 30-Day Plan at a Glance

Week Focus Main goal

Week 1 (Days 1–7)

Diagnosis and foundation

Know exactly what is weak

Week 2 (Days 8–14)

Skill building

Fix the weak areas one by one

Week 3 (Days 15–21)

Timed practice

Perform under real conditions

Week 4 (Days 22–30)

Mock tests and taper

Peak on test day, not before

Two rules for the whole month:

  • Keep an error log. Every mistake goes in the notebook: what you got wrong, why, and what you will do differently. Review it every Sunday. This single habit is worth more than any coaching class.
  • Do not skip Speaking. It is the section most candidates in Bangladesh leave for the last week. That is a mistake. Ten minutes a day, every day, from Day 1.

Week 1: Diagnosis and Foundation (Days 1–7)

The goal this week is not to improve. It is to find out what is broken.

DayTaskTime

1

Full Listening + Reading test, timed. Mark it. Log every error.

3 hrs

2

Writing Task 1 and Task 2 under exam time. Get feedback or self-mark against band descriptors.

3 hrs

3

Record a full Speaking test with a friend or by yourself. Listen back. Note fluency, grammar, and pronunciation problems.

2 hrs

4

Learn the exact format of your test version. Set your target band. Build your daily timetable.

2 hrs

5

Listening: question types (form completion, multiple choice, maps). Practise one section, then review.

3 hrs

6

Reading: skimming and scanning. Start True/False/Not Given, the type most candidates lose marks on.

3 hrs

7

Review your error log. Start a vocabulary notebook by topic. Take the afternoon off.

2 hrs

By the end of Day 7 you should be able to name your two weakest skills. Most Bangladeshi candidates find that Writing and Speaking are the problem areas. If that is you, give them more time from here on.

Week 2: Skill Building (Days 8–14)

Now you fix things. This is the hardest week and the most important one.

Rest and review your error log

Aim to write four essays and four Task 1 responses this week. Get every one of them checked. If you have no teacher, swap essays with a serious study partner. If neither is possible, pay for three or four online checks — it costs far less than repeating the test.

For Speaking, record yourself every single day. Then transcribe one minute of it. You will hear your own mistakes clearly: missing articles, wrong tenses, flat intonation, and the pronunciation habits that come from Bangla.

Week 3: Timed Practice (Days 15–21)

From here, everything is under exam conditions. No pausing the audio. No extra ten minutes on Reading.

The mock on Day 18 is your checkpoint. Compare it with your Day 1 diagnostic. If your Writing has not moved at all, something is wrong — probably you are writing without feedback. Fix that immediately.

Week 4: Mocks and Taper (Days 22–30)

This week you do fewer new things and more of what you already know. Your goal is to arrive at the test centre fresh, not exhausted.

DayTask

22

Full mock test. Review it the same day.

Full mock test, then stop doing new material

28

Light review: error log, vocabulary notebook, Speaking Part 2 topics

29

Logistics day — see the checklist below. No studying after lunch.

Test day

Do not try to learn anything new in the last three days. It will only make you anxious.

Section-by-Section Notes for Bangladeshi Candidates

Listening. The recordings use British, Australian, and New Zealand accents, and Section 3 often has two or three speakers interrupting each other. Practise with the audio at normal speed from the start. Do not slow it down. Watch your spelling — "accommodation", "Wednesday", "forty" versus "fourteen" cost real marks. Write answers in capitals on the answer sheet if your handwriting is unclear.

Reading. Time is the enemy, not difficulty. You have 60 minutes for 40 questions and no extra transfer time. Aim for 17–18 minutes per passage and keep 5 minutes to transfer answers. Never leave a blank — there is no negative marking.

Writing. This is where most candidates lose their band. Two specific problems I see constantly: (1) Task 2 answers that list ideas without developing any of them, and (2) Task 1 answers that describe every single number on the chart instead of the main trends. Learn the structures, then practise them until they are automatic. For paper-based tests, keep your handwriting legible — examiners will not struggle to read your essay; they will just mark it lower.

Speaking. Fluency matters more than big words. A simple sentence spoken confidently beats a complicated one delivered with long pauses. Three habits to break: apologising ("sorry, my English is not good"), answering in one line, and memorising answers. Examiners are trained to spot memorised responses.

Pronunciation points that Bangla speakers should practise: /v/ versus /b/ ("very" is not "bery"), /θ/ and /ð/ ("think", "this"), final /s/ and /z/, and consonant clusters at the end of words ("asked", "texts"). Ten minutes a day with a mirror or a recording app will help.

Resources That Are Actually Worth It

Free:

  • Cambridge IELTS 15–19 — the only books that closely match the real test
  • British Council's Road to IELTS and IDP's IELTS Prepare — free modules come with your booking
  • IELTS Simon and IELTS Liz blogs — excellent for Writing structures
  • YouTube: IELTS Liz, E2 IELTS, and BBC Learning English for listening and pronunciation
  • Facebook groups for IELTS Bangladesh and Dhaka speaking partners — useful, but be careful who you practise with

Paid, if your budget allows:

  • Three to four online essay corrections (roughly BDT 500–1,000 each)
  • One official mock test at the British Council or IDP centre in Dhaka (check current prices — usually a few thousand taka)
  • A short coaching course only if you genuinely cannot self-discipline. Most people do not need one, and BDT 8,000–20,000 is a lot of money for what is usually just structure and a speaking partner.

For books in Dhaka: Nilkhet Book Market has cheap photocopies of Cambridge books. Buy the originals if your budget allows, but if money is tight, do not let that stop you from preparing.

Practical Checklist for Test Day

  • Bring your valid passport. This is mandatory. An NID is not accepted for IELTS registration in Bangladesh.
  • Arrive at least an hour early. If your centre is in Dhaka, add an extra 45 minutes for traffic. There are no exceptions made for latecomers.
  • Leave your phone at home or hand it in as instructed. Having a phone in the exam room can get your result cancelled.
  • Eat properly before you go. The test runs for nearly three hours and you cannot leave.
  • Know your centre's address in advance. Check it the day before, not on the morning.
  • Sleep. A tired brain loses more marks than a weak vocabulary.

If You Have Less Than 30 Days

If you have two weeks, cut the plan in half: do the Day 1–3 diagnostic, then jump straight to timed practice and mocks. Skip the skill-building phase. Your score will improve less, but you will at least be familiar with the test format, and familiarity alone is worth a few marks.

If you have one week, do three full mocks, review them carefully, and practise Speaking daily. That is all you can do.

Final Word

The people who improve fastest in thirty days are not the ones who study the longest. They are the ones who find their weaknesses early, get feedback on their writing and speaking, and practise under real conditions instead of in comfortable ones.

Thirty days is enough time to prepare properly. It is not enough time to panic. Start with the diagnostic, keep the error log, and let the plan do the rest.
