How the banks are built
Every question is written against the body of knowledge a Green or Black Belt is actually examined on, weighted the way real papers weight it. You don't just get a score — every answer comes with the reasoning, so a wrong answer teaches you the concept you missed.
- Exam-realistic distractors — the wrong options are the plausible traps real papers use, not filler.
- Worked explanations — why the right answer is right, in one or two sentences of plain English.
- Domain coverage — practise the whole syllabus, not just the statistics you already like.
- Instant access — pay, and the bank opens in your browser straight away. No waiting, no accounts to create.
Free first, always
The 15-question sample is the honest starting point: same question style, same explanations, no email required. If the sample helps you, the full bank is the same experience at full length. If it doesn't, you've spent nothing and learned where you stand.
