How hard is the ISTQB Foundation Level exam?

Mostly understanding, not recall: 24 of the 40 questions are K2, and 8 are K3, where you apply a technique to a new case.

Questions40 multiple choice, one point each
Pass mark26 of 40 (65%)
Time60 minutes, or 75 in a non-native language
PrerequisitesNone
Question levels8 K1, 24 K2, 8 K3

What makes it hard

  • Close terms: error, defect and failure; confirmation and regression testing; review types. The wrong option is often the neighbouring term.
  • Techniques: 5 K3 questions in chapter 4 (partitions, boundary values, decision tables, state transitions, ATDD) and 3 in chapter 5 (estimation, prioritisation, defect reports).
  • Select TWO questions score only when both answers are right.
  • Time: ISTQB expects about 1 minute for a K1 question, 1 to 2 for K2 and 3 for K3.

What makes it easier

No prerequisites, one point a question and 26 of 40 to pass. The K3 techniques reward method over memory.

Question 1FL-4.2.2 (K3) Boundary value analysis
An infusion pump accepts flow rates from 1 to 999 mL/h in whole numbers. 0 or below shows "no flow" and 1000 or above shows "over limit". What is the minimum number of test cases for 100% 2-value boundary value analysis coverage?
Question 2FL-1.3.1 (K2) The seven testing principles
A registration form has 12 fields that each accept many values. The team lead wants every combination tested before release. What is the BEST advice?
Question 3FL-2.2.3 (K2) Confirmation and regression testing
A defect causing wrong late fees in a library app has been fixed. The tester reruns the tests that failed because of it. What is this?

Is the ISTQB Foundation Level exam hard?

It is one of the gentler professional exams. Most lost marks come from the chapter 4 techniques and near-synonym terms.
