This will be always the same value:
n = p0 + p0 * (percent/100) + aug;

So you will end up in an endless loop

I am new, so I do not know if this is usual or not, but while I pass all the tests I get a there was a server side issue kind of message (seems to be a standard alert window). I've tried 3 times, I'll try to solve again later. It happens both when I just run the tests and when I want to send an attempt as well (in javascript if it matters).
