44 tests per skill. 176 across all four. Choose Strict mode for real exam pressure, or Breath mode when you're still building confidence.
Not just a band number. Every test names the exact mistake, the sentence it lived in, and the pattern behind it. Then it tells you how to fix each one.
Mistake Memory tracks every session. See which slips you've fixed, and which ones are still capping your band, so practice stops being random repetition.
How Mistake Memory works
Everywhere else
Tomorrow, the same mistakes will be waiting for you. Nobody's keeping count.
At Zoju
Mistake memory · “Past/future tense”
By week 4, that mistake stops costing you marks. Mistakes you stop making.
Most apps show you a score and move on.
Zoju checks Reading and Listening against answer keys, grades Writing and Speaking by criterion, and remembers what keeps costing you marks.

Two modes, two jobs. Breath mode slows the clock so you can learn. Strict mode runs the real exam timing. No aids, no second chances. Switch when you’re ready.

Same mistakes, every test? Not for long. Mistake Memory flags the slips you keep repeating and tells you when they stop, so you see what’s actually working, not just hope it is.

Reading and Listening show answer-key breakdowns. Writing and Speaking break down by IELTS criteria, so you know what to fix, not just what you got. Practice estimates, never official results.

We take your actual answer and show you how to lift the band. Better vocab where you forgot it. Clearer structure where you wandered. The grammar fix where you slipped.

British, Australian, American. The accents IELTS actually throws at you. Real exam audio, run the clock, no subtitles. The same pressure you’ll face on test day.
Tutor quality is a lottery. ChatGPT can't grade IELTS. Coaching institutes cost more than a flight. Zoju was built for one test. The price reflects it.

In most apps, you don’t — that’s the whole problem. Zoju tracks your estimated band, your recurring mistakes, and per-criterion progress across every session. You see what you’ve fixed and what’s still costing you marks. Real trends, not single-test noise.
It can help if you act on what’s costing you marks. Most retakers keep practising the same way and getting the same band. Zoju’s job is to name the recurring slip (the article you keep dropping, the topic sentence you keep skipping, the question type that keeps catching you out) so practice stops being random repetition.
Each score is a practice estimate, not an official result. The real value is the criterion-level breakdown and pattern tracking that shows what’s costing you marks.
We’re an affiliate partner of British Council IELTS in Thailand, which is a referral arrangement — it doesn’t make our practice content official or endorsed. Band estimates are practice indicators, not official IELTS scores. The official test is delivered by British Council, IDP: IELTS Australia, and other accredited test centres. Zoju itself is independent — our tests, questions, analysis, and band estimates are all created by us.
No. If one module is dragging your band down, focus there first. Zoju keeps the other skills visible so nothing slips.
Strict mode recreates exam conditions with real timing and no aids. Breath mode slows things down so you can experiment and learn without the clock.
ChatGPT can rewrite an essay. It does not give you full answer-key Reading and Listening practice, remember your pattern history, or stay anchored to IELTS task flows. Zoju is purpose-built for IELTS: Reading and Listening are checked deterministically, while Writing and Speaking use criterion-level AI feedback and remember your recurring slips across sessions.
Yes — and it’s generous. You get 44 reading and 44 listening tests with full answer analysis, completely free and unlimited. Plus 2 AI writing evaluations and 2 AI speaking evaluations to try the feedback before upgrading. No credit card required.
Real prep is about quality feedback on repeated practice, not cramming 50 essays before the test. 20 a month is roughly one a day — focused enough to spot recurring patterns, generous enough to never block you on a good study run. Your evaluations refresh on the 1st of each month.
