Premium Question. Does it carry over?

[AuraLove]

Say I go premium for 3 months and then have to stop paying to handle unexpected things. Would I lose all my progress in ranking up? also how hard is it to rank it up?

premium benefit only applies when you're premium, when it expires, it's just disabled until you bought premium again. 

if they post about the "exp" required to rank it up to lv 10, someone will be able to calculate the $ > max level for ya.

but you keep all your XP if you stop paying for one month?
