| I think the problem is that the exam can only cover maybe 20% of the curriculum. So even if you know 90% of the material, you could be unlucky and get ~50%. Whereas someone else that only knows 20% could be very lucky and get ~100%. But everyone knows this going in. Even small gaps in your knowledge can have a big impact on your result. |
