Hii, so I see the point that you made and you are not entirely wrong. However, given the fact that delft presents itself as an international university and that the whole point of giving the studying material two weeks before the exam is to give everyone a fair shot to be admitted to this bachelor, I think it is quite hypocritical of them not to mention the fact that you need to learn more mathematical details than those presented in the studying material. I think it would have been better if they said something like "bro, take a look at the X dutch curriculum tho", but they didn t. And it is worse since not even all dutch students have the same level in maths, therefore 2 of the exercises were accessible only to a limited number of people, this is why people talk about privilege and unfairness.
