[Misericordias]

I have a question regarding the jlpt exams; specifically, n1 and n2. My professor said that in order to take n1, we have to take n2 and pass or else we would not be eligible to apply. However, I know that from n5-n2, it is not required to take the previous test in order to take a higher level test.

I can see why n1 needs a n2 requirement, but I am not too sure if that is true, or it's more of a strong encouragement/hint to first take n2.
