Question Type
Identify what the question is really testing.
Every ISTQB question falls into one of five cognitive types. Knowing the type tells you HOW to think before you even read the options.
Knowledge (K1): recall a definition or fact. Understanding (K2): explain why or compare concepts. Application (K3): apply a technique to produce an answer. Scenario: a short story you must interpret. Best Answer: several options are correct — but one is the strongest.
How to apply it
- Knowledge → match the wording to a definition you memorised.
- Understanding → look for 'why', 'because', 'difference between'.
- Application → expect calculation or technique steps (e.g. equivalence partitions).
- Scenario → read the story twice; facts hide in the details.
- Best Answer → watch for 'BEST', 'MOST', 'PRIMARY' — all options may be true.
