Expert take: what ISTQB Foundation really tests

With 40 questions and a 65% bar, the test-design-technique questions (equivalence partitioning, boundary values, decision tables) carry the most application-level weight and deserve focused practice.
Preparation tips
- Study straight from the CTFL v4.0 syllabus and learn the glossary definitions precisely.
- Drill the test-design techniques — they carry the application (K3) questions.
- Take official sample exams to get used to the exact wording and 40-question pace.
Common mistakes to avoid
