There can be no simple answer. First, it is not clear that the hardest thing to know - if such a thing exists - has been found yet. Maybe it is too hard even to find. Also, different people find different things hard: not just in mathematics but in every aspect of life.
Math is the hardest question, if you dont understand it.
AP CALCULAS AP CALCULUS* is not the hardest math. Analysis, Set theory, Algebra, Topology, Calculus and Number Theory
HL math
Maths isn't really as hard as you think, if you pay attention in class and know the methods for whatever topic its about it is really easy. Math test are hard or can be hard because the teachers are discovering what level you should be and things your not really good at, they'll try their hardest to help you so that your on the same task as everybody else. Don't get too stressed when a math test is to start, just study your hardest and you'll get a very good result. They best thing is that if you think you've done your hardest well then you on the right track.
Pre-Calculus
That's hard to say.
Definately not my friends. As long as you know numbers, you know math. Once you get the hang of it it's so easy, that it's fun!!!!!!!!!!!!!!

Foucault's last conundrum.Fermi's last theromExact value of Pi.
The hardest question is too difficult to conjure.

Try your hardest, forget every thing that's happening in the room and concentrate. The night before revise really hard.
