<p>Anyone know what the calculations are to estimate your score?</p>
<p>the one with the solutions was hard. the rest were ok</p>

</p>
<p>I believe it's
0.96 x MC Raw + 1.54 x FR Raw </p>
<p>That's based on 160 possible points, with 45% coming from MC and 55% from FR (assumes 57 max raw in free response, as in princeton review). I'm not exactly sure about the curve, though.... estimates abound.</p>
<p>I omitted 11 or so. That's what I typically did anyway on practice AP Chem tests, so I wasn't worrying too much. The initial questions threw me off a bit at first -- I think I guessed on several when I finished the MC early and came back. I don't know if that was a wise decision!</p>
<p>Personally, I think the MC this year was harder... I'm aiming for a weighted Section I score of at least 50 points, because on the past practice tests I took, I had about 54 points weighted on the Section I -- and I made a 5 without doing extremely well on my FR. (I did the 1999 complete test and 1984 as well.)</p>
<p>I lurve Net Ionic. I was unsure about one rxn but I definitely skipped those I did not have a clue about. I should be okay. <em>crosses fingers</em></p>
<p>The free-response...reasonable. I was happy about the selection, except for the lab question. I screwed that one up and probably only earned 2 points. The rest, though...I was so lucky! The topics chosen were ones I understood well.</p>
<p>I hope I get a 4! I should at least get a 3; if I don't manage that, I'll be really shocked/disappointed. I really only want college credit, but getting a 5 would be wonderful for me. Considering how much I suck at math and science. :)</p>
<p>I'm surprised how many of you thought the lab question was really hard. Were you all preparing for a titration one (makes sense because they usually are that). But still, I thought this lab question was a lot easier than other ones; the 2nd part everyone should be able to get as long as they prepared for possible net ionic reactions, and the 3rd part is easy as long as you know your solubility rules - otherwise you basically have no chance of getting any points for part c.</p>
<p>i omitted 7. i got burned a lot in physics from answering too much, so i didn't. I'm pretty sure about the ones I put down, and max. got 15 wrong (v. conservative estimate) so that's about 50 points. (minimum)</p>
<p>I did perfect on 1 and 2 (these were v. easy problems!), made a minor mistake on the rxn set (they MIGHT take my complex ion answer, they might only give 1 pt) - but that would be the only problem, so max -2 there, 5 I guessed on a, but everything else was correct. I'd say minus maybe 3 max. cuz I my bs was logical, 6 I forgot the angle, but guessed with right on formal charge (although didn't get explanation) so probably -3, and 7 i did perfect on. So I got 75 on the FR. </p>
<p>That gives me 125, which I'm very confident is a 5. My rxn set error bugs me though; I was so prepared to massacre that thing! Arg, I should've picked a different reaction. </p>
<p>My best AP.</p>
<p>Just calculated a weighted conservative estimate for myself for points:</p>
<p>58 right on MC, 17 wrong
6 on FR1
2 on FR2
15 on FR4
7 on FR5
4 on FR6
8 on FR7</p>
<p>Gets to 118 points - even if I mess up a little bit more on MC, I still can get a 5 at it's highest (107) - if curve is nice, 100 could get a 5. YES!!</p>
<p>No, but my lab partner did, and he would agree with you.</p>
<p>Would somebody like to tell me how many points each FR is worth?</p>
<p>:)</p>
<p>1: 10 * 1.76
2/3: 10 * 1.76
4: 15 * 0.88
5: 10 * 1.32
6: 8 * 1.65
7/8: 8 * 1.65</p>
<p>hmm, i got a 70/75 on the 2004 released exam, didn't think this year's was that much harder, so i think i got 65+ on the MC. I answered all 75 questions with 25 minutes to spare.</p>
<p>FR was obscenely easy. the only hard question was #5(or 6?), the one on bonding or something.</p>
<p>yeah. Never covered formal charge...grr. It was 6. FR 1 and 2 were great, although the lab question was totally unexpected. the first part - the 'hot splint' test was freaky.</p>
<p>i remember reading formal charge in zumdahl, but i forgot it during the test.. oh well, its only one point from that question. i also totally skipped the lab. i calced my score very conservatively and i have a solid 4 with possibility of a 5</p>
<p>Yeah, I remembered the term formal charge, but couldn't remember what it was either . . . oh well.</p>
<p>The MC was ok, my school has a pretty bad teacher, so I really wish I knew more . . . . I'm pretty sure I nailed #8, 1 wasn't too hard either. I actually chose 3 since I had just reviewed what that essay was about. Oh, and parts of 5 were hard.</p>
<p>FLAME TEST GOT OWNED GAWD</p>
<p>NITROGEN?
HYDROGEN?</p>
<p>oxygen was easy-----gets redder or darker red or probably ignite again if there is enuf oxygen but wth nitrogen and hydrogen? </p>
<p>BAKing SODA WAS ON THERE YES it was the one with sodium in it right</p>
<p>MACCASWEETIE - On that 1999 test that you have, what composite score do you need for a 5. </p>
<p>I'm trying to see if composite scores change significantly from year to year...we already know that in 2002 you had to get over a 107 composite for a 5. But since 2002 was really easy other years might have had lower composite scores for a 5.</p>
<p>Therefore, MACCASWEETIE, please post the score needed on that 1999 exam you have.</p>
<ul>
<li>Thanks</li>
</ul>
<p>If anyone else knows the composite score needed for a 5 for other years, please post too.</p>
<p>I posted this for other threads too but this is the one for 2002
I'll give you a really specific method.
first MC
(number correct-wrong/4)<em>.96=weighted MC
FRQ really complicated
question 1 score out of 10 * 1.76
question 2 or 3 score out of 10</em>1.76
question 4 out of 15<em>0.88
question 5 out of 10</em>1.32
question 6 out of 8<em>1.65
question 7 or 8 out of 8</em>1.65
add all of them up
107-160 5
85-106 4
61-84 3
42-60 2
0-41 1</p>
<p>i know thanx but i was asking for the composite score needed for a year other than 2002</p>
<p>on frq number 8 , did everybody realize that it was a electrolitc cell
thus the reduction occured in the anode , i hope im right...</p>
