I bet most people don't talk about their studying, and if you don't see the person studying, what stands out is their ability. So if the person goes home and spends twice as much time studying as you do, you still only see the part where they demonstrate their knowledge. If they studied ahead, they'll look like they know everything when really they are working twice as hard as you. Basically, we humans are really bad at judging things, particularly abstract things like "intelligence". Heck, we can't even really define it yet. Just get your results, and be happy with those.
