<p>How does the college board normally do the curve? Do they average people's scores or something and then adjust the score conversions so that about the same number of people get an 800 as usual?</p>
<p>lol my chem teacher got a heart attack before she finished teaching us stoichiometry... so i had to learn oxidation/reduction, organic chem, nuclear chem, and yea we almost never did lab in her class, so lab analysis. I'll be happy with a 700</p>
<p>The first set of questions: acid rain is b/c of calcium?<br>
what did u put for greenhouse effect? and for the gases absorb radiation one? </p>
<p>4L hydrogen + 3L oxygen question--> wats left? </p>
<p>Thanks.</p>
<p>no, acid rain is because of sulfur. greenhouse effect i checked after i got home: it's because of infrared radiation. ozone layer absorbs ultraviolet radiation.</p>
<p>and i omitted the latter question.</p>
<p>1 L of oxygen is left because twice the hydrogen is needed to produce water. At least, I think so.</p>
<p>This test was HARD. I scored a 5 on AP in May 05, and it still kicked my butt.</p>
<p>lol i think i was the first one to complain about how hard the chem test was.. im glad everyone concur!!...i guessed like half of it by randomly bubbling 'c's ...:( unfortunately, i cant cancel my scores b/c i think i did well on the maths IIC. oh well...i guess i will give up on chem. i think its ridiculous how short the time was for like 85 questions.</p>
<p>if it was 85 all comcept questions, it wouldnt take all that long to answer. but they mix half calculations with concepts and gives us less than a minute per question.
stupid chem</p>
<p>they did have a few simple questions though. Like in the true false section they had "Isomers havet he same number of protons and electrons but different number of neutrons because different mass numbers for the same element are called isomers."</p>
<p>That was obviously f f</p>
<p>Agh this test ****ed me off because it seemed to oscillate between incredibly easy questions and incredibly random/difficult ones. Anyone else get this impression of the test?</p>
<p>Yeah, I definitely got that impression too. They really need to have some sort of natural progression of question difficulty like on the SAT I and the Math 2c test.</p>
<p>oh btw on the test they had a question on whether covalent bonds are broken during condensatoin. They are not right?</p>
<p>right, they aren't. was that on a true-false?</p>
<p>how many can we get wrong to get a 750?</p>
<p>there is no way to tell yet.
I think lots of people did well and lots of people didn't. the so-so people is not that many</p>
<p>What was the answer to the question asking which reaction was NOT a redox reaction? The answer choices included a combustion reaction, an acid-base neutralization reaction, and some others</p>
<p>combustion</p>
<p>redox is any reaction that has a oxide state change</p>
<p>Thank god I at least got that one right.</p>
<p>for that electrochem question.. it was the same sign with what they had .. wasn't it on the cathode? in that case the substance would be reduced.. so it was supposed to have 2- sign.
And yeah I put paper chromatography for ink thingy. It was pretty hard wasn't it? A LOT harder than last June's. I took it then as well... just trying to raise my score a bit more :></p>
