<p>@jy2013 That sounds like a great answer. I was really low on time so I put “it depends on the number of valence electrons” :)) </p>
<p>Ok so first of all, I got frightened about this exam, b/c my teacher told me you need 88% (not a typo) for a 5, and 70% for a 3. I want a 5 – I had barely made an 88 raw score on his tests – I avg like 85ish. But free response was usually my stronghold and mc was the place I usually screw up.
Today was just the opposite. The mc was really easy – expecting like a 53-54/60 but the frq was like bizarre!! The course description said that there are 3 long and 4 short frq. The same CB frqs had like 2 parts to the short answer and like 4 parts for the long. Well today was different, as you all saw.
I had 3 min for the last frq, totally BSed that one about orders and pressure and left like two parts blank on the first frq b/c I was running out of time. The others were fairly doable. I am still hoping for a 5, but the back of my mind tells me that I might just land up at a 4. </p>
<p>ClF3 was Tshaped and had two unshared</p>
<p>I would be so happy if a 5 was 60-65%</p>
<p>From what I’ve read so far (on here and on twitter), it sounds like many people did not do so hot. And many more people got severely destroyed. I don’t think anybody expected the exam to present itself the way it did, and I think the curve will be generous. Chemistry, unlike Bio, is much harder to teach. And, I think College Board understands that as well. </p>
<p>Gah I have another AP test tomorrow that I have to study for but I can only think about chem :’(</p>
<p>Does anyone wanna predict the curve? I think I got 50/60 on multiple choice and maybe 23 / 46 on free response</p>
<p>@Hawkace I’m pretty sure 76% is right… I think there are 2 different tests or that it was asking for the mass % of two different things. I remember it asking for the mass percent of I in KI which is 76%… anyway… don’t worry so much… I took a practice test for the old curriculum and got 55/75, and my teacher had a grading scale for the old AP test and that was a 5. And this year, the curriculum got harder, so even more people are going to do worse, making the curve even more generous. Don’t stress!</p>
<p>^^^ optimistically that’s what I got… But I don’t like thinking optimistically.</p>
<p>Yeah, I concede that 76% is probably right. For some reason, I love Cl so much that I accidentally used that instead of I. F M L</p>
<p>@jy2013 It was C.) 6.0 KJ</p>
<p>It’s not 76%. It’s close to 30. The KI tablet has an unknown amount of sugar in it, and 76% assumes pure KI in the tablet. You needed to use the amount of I in the precipitate as the mass I in the KI tablet. </p>
<p>I though the FRQs were so much easier than any of the practice tests I have taken. I always thought that everyone got the same questions for Free Response, cause when they release them, theres only one set…</p>
<p>It is not 76%. It is like 30.5%. The answer is 76% if the question asked what the percent of I- is in a pure tablet, but the tablet had H20 that needed to be accounted for so the answer calculated using the number of moles in the previous question is 30.5%.</p>
<p>Does anyone know if the scores of people who take the late exam (on may 22) will factor into the curve?</p>
<p>Ok for everybody stressing out about the FRQ and the curve and everything else: Keep in mind that the test is graded relatively to the rest of the nation. As you all probably know, collegeconfidential is usually filled the brightest kids in high school… So if the best of the best think that the FRQ was hard… imagine what the average kid thinks. The national average score on last years exam was a 2.92, and the curriculum only got harder. That means a more generous curve for people that actually know what they’re doing. My teacher was telling me about her friend that teaches AP Chem in New York, and he didn’t have enough time to cover ACID-BASE or Electrochem and he barely got through Equilibrium. Think about how the test went for them. I also have a friend in AP at a school near mine, and their teacher lets them bring in a periodic table with anything they please written all over it… Imagine how ill-prepared students like this were. I don’t know about you guys, but I find comfort in the fact that there are so many more people that were less-prepared / less-intelligent. (not to sound cocky, but chemistry is my ■■■■ yo)</p>
<p>The FRQ’s were so much easier than I expected, yet I somehow messed up some of them and nearly ran out of time. ;~;
I’m sitting at a estimated 45-50/60 for MC (didn’t study buffers, silly mistakes) and estimated 30-40/46 for FRQ. Depends on how my long FRQs are graded and how nice they are about it.
Hopefully the curve will be generous ^_^</p>
<p>I think the curves are predetermined.</p>
<p>Are AP tests curved according to how other students did or is the curve predetermined, like in SAT?</p>
<p>Curves are not based on the rest of the nation. The curve is already set prior to the release of the exam</p>
