Aye, one would think... but from the information presented, he'd actually need to score negatively (not possible?) to drop his average percentage down to 50%.

Yeah I'm getting 38,5% of the entirety of questions asked so far have been answered correctly, which means that of the remaining 30% of questions, he has to answer 38,333333...% correctly.

Am I right?

Technically it's 38.5% of the entirety of questions--including the ones that haven't been asked yet. As his current grade indicates, he's answered 55% of the questions asked up until this point correctly.

But yeah, the numbers are right.

Oh yeah, that's what I meant, just wrote something else

Xei, most of the software I use in school actually uses . for decimal stuff, like Graph and MathCad. As far as I know, it's mostly just danes that still use , for decimals.
