<p>Did most of you get the kinetics one? I’m disappointed in myself for missing both 3. d and e…</p>

<p>I for sure missed 1f, 2c-e, and 3d. THAT’S IT. I’m so happy. I came out of that test thinking I had done way worse.</p>

<p>I solved 3d incorrectly, but yanked my answer down to 3e and solved that one correctly.</p>

43

<p>I think the curve will still be fairly lenient/regular. Although the questions were easy, they asked for bizarre things, which I’m pretty sure stumped a lot of people.</p>

<p>Heck, some questions stumped 50%+ of CCers.</p>

44

<p>Does anyone mind posting the answer to 6.e and 1.f? Thanks</p>

45

<p>I think I need like a 75% on the MC to get a 5(conservative estimate). What % do you guys think you got on the MC?</p>

46

<p>@thebioguy: Do you know where I can find the link to Form B on their website?</p>

47

<p>MC was wayyy harder than usual; I didn’t even finish the last three problems and on my practice tests I finished with ~20 mins to spare! Aced FRQ part B, got ~50% of part A … we’ll see. I’ve estimated that I need a 50/75 MC for a 5 … which sounds like a ton wrong, but DANG that MC section was hard. So it’ll be borderline 4/5.</p>

48

<p>My chem teacher received the free response today and he even admitted it was very difficult. Hopefully the curve will be good. Btw we can discuss right? If teachers have received it?</p>

49

<p>where are the scoring guidelines???</p>

50

<p>I’m expecting 45 on the MC. I just need the scoring guideline for a good guess on my score. Expecting a mid 4. I thought the guidelines released 48 hours later?</p>

51

<p>I can’t find any information on APCentral/CB about when the scoring guidelines are released. Anyone else know?</p>

52

<p>Scoring guidelines are released over the summer. The free response is now on AP central.</p>

53

<p>My teacher looked at the free response and said it was extremely easy lol.</p>

54

<p>I probably got 50 correct for MC, and hoping for ~95% on FRQs, which I thought were amazingly easy.</p>

55

<p>Maybe a mistake here and there (feel free to let me know if you see any errors), but these are the answers:</p>

<p><a href=“https://docs.google.com/document/d/1z2OeB88EdaEguADJFu4uDwG8VTSNPN8O6ftE0VT_xmc/edit[/url]”>https://docs.google.com/document/d/1z2OeB88EdaEguADJFu4uDwG8VTSNPN8O6ftE0VT_xmc/edit&lt;/a&gt;&lt;/p&gt;

56

<p>My teacher said that about 75% of the FRQ on Part A was pretty simple, but the others in Part A were tricky (he specifically mentioned 1f, 2c-e, 3c-d).</p>

57

<p>Ah I for sure missed 2f, 4c(ii), and 6e(iii).</p>

<p>And for the IMF, polarity, etc questions, I hope I BSed it good enough.</p>

58

<p>So, for FR #4 Part (a), was it supposed to form carbonic acid or just go directly to CO2 + H20?</p>

59

<p>4a is tricky. For the most part CO2 doesn’t react with water, it just dissolves as CO2, hence the carbonation in soda. However some of it does react with water to form H+ and HCO3- (the dissociated form of carbonic acid), making it slightly acidic.</p>

60

<p>Straight to CO2.</p>
