Your result

Practice, not the exam. This assumes papers of equal difficulty, a steady level and independent questions. Real IELTS papers are equated and passages share difficulty, so real results can fall outside this range.

Questions people ask

Are IELTS practice test scores accurate?

Practice papers are useful if they are full, timed and new to you. Real papers are equated, so the same marks can give a different band, and scores on repeated papers overstate your level.

How many practice tests do I need for a reliable picture?

More helps: with one mark the likely range is wide; with four or five it narrows. The model still assumes the papers are equally hard.

What band is 30 out of 40 in IELTS Reading?

On IDP's indicative table, 30 correct in Academic Reading is band 7.0 and in General Training Reading it is band 6.0.

How we work this out

What it does

Enter your recent Reading or Listening practice marks and see the likely range for your next comparable practice paper, as marks and bands.

IELTS Listening, Academic Reading and General Training Reading practice papers out of 40, one to six of them.

Method

  1. We start from a flat assumption about your accuracy and update it with every mark you enter (a Beta(1,1) prior and a binomial model of 40 questions).
  2. That gives the chance of each mark from 0 to 40 on one more practice paper of the same difficulty.
  3. We report the middle mark and the range that holds 9 in 10 of those chances, then read the bands from IDP's published indicative table.
