You can know a topic perfectly and still lose marks in an IB exam.
It happens in a strangely quiet way: you write what you know, the page fills up, and it feels like a good answer. Then the feedback comes back with the same message students hate reading: “Not focused on the question.”
Most of the time, that isn’t a content problem. It’s a command terms problem.
In the IB, command terms (analyse, evaluate, compare, discuss, outline, etc.) are the steering wheel. Content is the engine. If you don’t steer, you can drive a powerful car straight into the wrong wall.

What command terms mean in IB exams
Command terms are the instruction verbs in IB questions. They tell you how to respond, not just what to write about.
A quick way to feel the difference:
-
Describe = what it looks like, what happens, what the features are.
-
Explain = why/how it happens (cause, mechanism, effect).
-
Analyse = break it into parts and show relationships.
-
Compare = similarities and differences in a structured way.
-
Evaluate = weigh strengths and limitations using criteria, then judge.
If you treat like , you may write accurate paragraphs but miss the thinking skill the markscheme is rewarding.
