the curve varies with each test. if everyone did well, then it'll be a low curve. if everyone did bad, it'll be a higher curve. for instance, a raw score of 44 can be 800 on a test with low average score while it can be 780 on a high average score. so if everyone didn't do good, we get a higher curve.
I'm pretty sure the curve is predetermined. Plus I think the curve for this test will be on the slightly generous side; this test is slightly more challenging than the released exams, I think.
Yeah, I heard the curve was predetermined too.
I also got E for the ax^2+bx+c=0 one. Haha, I just plugged it into my calculator and it came up with imaginary results.
Someone brought up this problem earlier: "does anyone remember the question: how many times does this function cross the x-axis? f(x)= xy^5-2x=3y+1 (or something like that?)." It was something I had trouble with too; I just plugged in 0 for y and you get two solutions for x?
Also, does anyone remember an exact number they got for the 6 inches from the plane, area of the circle one? I got 108pi.
They should make a Math IIIC for the last level with calculus. I would probably be easier (In the sense of higher average score) than Math IIC and Math I and many people would flock to that one. And it would be less competitive (In the sense of less number of competitors) because only juniors would take it near June and seniors would take it in the later months of the year such as September or October.
There would be far fewer people in general who would take it though since not many people get to calculus in their junior year. There's no point in taking it at the end of your senior year.
Which is exactly why it is good - those who can handle it have the chance to set themselves apart from the mob of people who would otherwise take Math IIC. Although it would screw over everyone who is left taking Math IIC because they would not be taking the most rigorous test.
The population one I think was 5 wasn't it? I can't remember, I just remember that you got a decimal which you would have to round up. Maybe it was like 3.2 and you rounded it up to 4. I can't remember the years.
