I could be totally wrong, as I just did some stuff that seemed right, but I figure... 44% 

OK, heres the situation: I have a math exam tomorrow. It is worth 30% of my whole year. I am

Thank you, now I don't have to study that hard lol. 

You need to get 38 and (1/3)% on the exam to have a 50% average. 

38% is correct. 

Is this a final exam? At my school, you had to pass the final (government) exam regardless of your total percentage for the year, so you might not be out of the woods yet . 

It's kind of a vague question and there are many ways to calculate grade averages. 

No, I'm pretty sure you don't have to pass the exam, just the course. Also, percentages aren't on the test, thankfully. 

Yea, from what he gave us I figure he only needs to score like a 16% on the test to maintain a 50% average. [50% ≤ 55% + .3*x] 

.7*55% surely. 

I don't understand the question, maybe because I'm not familiar with the school system you're using. Anybody who can rewrite it?

He has to get 50% of the answers right. In the tests so far, which constitute 70% of the total questions, he's scored 55%. 30% of the total number of questions remain. What percentage of right answers does he need? 

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.

I hope this isn't a college exam you're about to take. Because this question is very, very, very basic algebra.

Nah, it's the whole of Europe except the UK pretty much. I've had a few foreign tutors who haven't kicked the insidious habit. 

Two comments: 

Oh, okay. I didn't calculate for a weighted grade.

You left out a term. You didn't weight the current 55% grade. 

Haha  I've taken up to Calc III and this is what I have to show for it.
