ISTQB CTFL v4.0: where the 40 exam questions really come from

The ISTQB Certified Tester Foundation Level (CTFL, syllabus v4.0) is a 40-question multiple-choice exam. You have 60 minutes and need 26 correct answers (65%). If you do not take it in your native language, you get 25% extra time.

Most study guides give every chapter the same attention. The exam does not.

How the 40 questions are split

Chapter Topic Questions
1 Fundamentals of testing 8
2 Testing throughout the software development lifecycle 6
3 Static testing 4
4 Test analysis and design 11
5 Managing the test activities 9
6 Test tools 2

Chapters 4 and 5 are 20 of the 40 questions, and they hold all eight application questions (level K3). Chapter 6 is worth two questions. Spending a third of your time on tools is a bad trade.

What a K3 question looks like

K3 means you must apply a technique, not recall a definition. Example, boundary value analysis:

A field accepts an age from 18 to 65 inclusive. Which test values does 2-value boundary analysis give?

The answer is 17, 18, 65, 66: each boundary, plus its nearest value on the other side. With 3-value analysis you also take the neighbour inside the range: 17, 18, 19, 64, 65, 66.

If you can do this by hand, with equivalence partitioning, decision tables and state transitions too, you are covering the heart of chapter 4.

A way to spend your hours (my suggestion, not an ISTQB rule)

  • Give chapter 4 the biggest share, and do exercises, not only reading.
  • Read chapters 1 and 2 once carefully: vocabulary questions are quick points if you know the definitions.
  • Keep chapters 3 and 6 for a final pass.
  • Take mock exams early. Aim for 75% on mocks before the real exam, since the pass mark is 65% and you want margin.
  • Train under the same conditions: 40 questions, 60 minutes.

If you want a guided path

At AutomationDataCamp we run a CTFL v4.0 preparation: 2 × 7 hours online over a weekend (21-22 November 2026), then practice sessions and mock exams. It is taught in French. The price includes the official exam with a second attempt, from €450 VAT incl. if you fund it yourself.

If you prefer to study alone, the chapter split above is the part worth keeping.

Which part of the exam worries you most: the application questions of chapter 4, or the vocabulary ones? Tell me in the comments.
