You can see the required XP amount on the right side of the main dashboard page.
I want to know the xp needed for the next levels. Right now Im lvl 11 and I need 950k xp to lvl 12. I want to know how many xp I need from 12 to 13, 13 to 14, 14 to 15 and so on.
I could infer that the experience needed to pass from level n to n+1 should be 1000n(3/2)^n (it is certainly correct for n=10,11,12).
