Passing an exam tells you almost nothing about how intelligent someone is. Getting top marks measures memory, preparation, and familiarity with a format. It does not measure what happens when life puts something genuinely unfamiliar in front of you.
The best definition of intelligence I've come across is this: intelligence is how you act or react in a completely original situation. Something you have never faced before, with no notes to consult and nothing you've studied for. In that moment, everything you carry, your knowledge, your skills, your life experience, your natural instincts, has to surface all at once and work together to resolve whatever is in front of you.
The person who freezes, the person who improvises badly, and the person who reads the situation clearly and moves decisively: that gap between them is the gap in intelligence. A distinction on an exam is worth something, but it only measures what you already knew going in. How you assess the problem and go about resolving it is what defines how intelligent you actually are.
