Preparing for the ISTQB® Certified Tester AI Testing (CT-AI) exam? This course gives you 6 full-length practice exams with 240 original questions, written from the new CT-AI v2.0 syllabus.

Every exam follows the official CT-AI v2.0 exam structure: 40 questions, 60 minutes, and the same mix of learning objectives and K-levels as the real exam. You practice exactly what the exam tests, chapter by chapter.

What makes these practice tests different:

- Written for v2.0 – covers the updated syllabus content, including generative AI testing, red teaming, data pipeline testing, data representativeness, label correctness, statistical ML performance testing and deployment testing.

- Every option explained – you learn why the correct answer is right AND why each wrong option is wrong, so every mistake becomes a lesson.

- Syllabus references – each question shows its learning objective (for example AI-5.1.5) and K-level, so you know exactly what to review.

- Exam-style calculations – practice confusion matrix metrics (accuracy, precision, recall, F1), dataset constraint scenarios and metamorphic testing questions like the K3 questions in the real exam.

- 100% original questions – no copied or reworded official sample questions.

Topics covered across all 6 exams:

1. Introduction to Artificial Intelligence

2. Quality Characteristics for AI-Based Systems

3. Machine Learning

4. Testing AI-Based Systems

5. Input Data Testing for Machine Learning Systems

6. Model Testing for Machine Learning Systems

7. Machine Learning Development Testing

Important note about scoring: the real CT-AI exam is points-based (44 points in total; K3 questions are worth 2 points, and you need 29 points to pass). Udemy scores every question equally, so aim for at least 70–75% here to build a safe margin for exam day.

How to use this course: take each exam in timed conditions, review every explanation, revisit the syllabus sections you missed, and retake the exam until you consistently score above the pass mark.
