Every attempt draws questions you haven't met yet first · Pro.
A full-length paper drawn to the same domain weights, from the questions we rate hardest — the ones that combine two facts or weigh workable options against each other.
One exam domain at the real exam's pace — for the domain your last mock went worst in.
What's in a CT-GenAI mock paper
Each paper draws its questions per domain in the same proportions ISTQB publishes for the real CT-GenAI — so a mock that goes badly in one domain is telling you something a randomly-drawn quiz couldn't.
| Domain | Official weight | Questions drawn | Share of paper |
|---|---|---|---|
| Introduction to Generative AI for Software Testing | 17% | 7 | 18% |
| Prompt Engineering for Effective Software Testing | 28% | 11 | 28% |
| Managing Risks of Generative AI in Software Testing | 25% | 10 | 25% |
| LLM-Powered Test Infrastructure for Software Testing | 13% | 5 | 13% |
| Deploying and Integrating Generative AI in Test Organizations | 17% | 7 | 18% |
| Total | 100% | 40 | 100% |
What a CT-GenAI paper is shaped like
Which way this particular paper applies pressure.
The clock
At roughly 1.5 minutes a question, the pacing is comfortable but not generous. You can afford to think on a hard question, and you cannot afford to do it twice. Most candidates finish with time for a second pass if they keep the first pass moving.
The weighting
Prompt Engineering for Effective Software Testing is the largest domain at 28%, but with 5 domains in play no single one decides the result. A mock score here is usually a fair reflection of overall coverage rather than a verdict on one topic.
The standard
The pass mark is 30 on the 0–46 scale. Because scaling adjusts for the difficulty of the particular set you were served, there is no fixed number of questions that guarantees it — which is exactly why a single mock result means less than a consistent one.

What trips people up on a CT-GenAI mock
CT-GenAI is marked against the syllabus, not against how you use AI tools day to day. Hallucination, reasoning error, bias, few-shot prompting, meta prompting, RAG, fine-tuning and LLMOps all have precise syllabus meanings, and the distractors are usually ideas that sound right to anyone who has used a chatbot. When you miss a question, check the syllabus wording rather than your own habits.
Prompt engineering is the heaviest chapter, and it holds almost all of the two-point apply-level questions: given a test task, pick the prompt structure or technique that fits it, or spot what a prompt is missing. These questions reward practising with prompts, not reading about them, so rehearse them until you can name the missing part of a prompt quickly.
The risk chapter is the second biggest and the easiest to underrate. Expect output to judge: is this a hallucination, a reasoning error or a bias, and which mitigation fits? Privacy and security questions turn on what you send to which model, so keep the data-exposure risks and their mitigations distinct.
Infrastructure and adoption are small chapters with a lot of vocabulary: RAG versus fine-tuning, agents, LLMOps, shadow AI, choosing between an LLM and an SLM, and the adoption phases. They are easy marks if you can tell the terms apart and easy losses if you skimmed them.
The real exam gives two points for each apply-level question and one for the rest; our mocks count every question the same, so treat a mock score near the pass line as borderline and look at your prompt-engineering accuracy first.
