How accurate is ExamForge?

Every prep tool claims accuracy. We measure ours against real IELTS results that students self-report after the exam, and publish the numbers — wins, losses, and weaknesses.

Building our calibration dataset

We're collecting our first 50 verified results — be one of the first to report.

We've received 0 reports so far. We won't publish a headline accuracy number until we hit a sample large enough to be honest about.

Methodology

How we measure ourselves.

After every student takes the real IELTS exam, we ask them to share their official Test Report Form scores. We compare their actual band scores against the prediction from their most recent mock test taken on ExamForge before the exam.

Each submission is reviewed manually by a human (we eyeball the screenshot of the Test Report Form). Submissions that fail review are excluded and the bonus is revoked.

We report Mean Absolute Error (MAE) — the average gap between what we predicted and what they actually scored — both overall and per section. Lower is better. Anything above 0.5 bands is published only when we've fixed it; honesty about errors only helps when we have a path to closing them.

Publishing bad numbers is fine. Publishing fake numbers is fatal.

In their words

From students who've sat the test.

  • ExamForge predicted 7.0 overall. I scored 7.0 on the real test. The Writing feedback was the closest I got to a real examiner.

  • My mock score was 6.5 Speaking and I genuinely got 6.5 in the real exam. First prep tool where the number meant something.

  • Reading and Listening predictions were spot-on. Writing was 0.5 high but they flag that publicly — I respect the honesty.
