<p>I really hope it’s 95. D:</p>
<p>I know that the multiple choice will be what carries me through, and I can only hope that I avoided enough errors on the free response to barely scrape by with a 5.</p>
<p>Same mc is my only hope</p>
<p>Can anyone help me with the last part of question 1? Where we had to find [NH4+]… I cant figure it out</p>
<p>Unrelated to the AP test, but I have a chemistry contest tomorrow and was hoping some of you could help me out with a few questions.</p>
<p><a href=“Home | Chemistry | University of Waterloo”>Home | Chemistry | University of Waterloo;
<h1>14, what I did was calculate that O2 was the limiting reagent, and from that got 0.1875 moles, then multiplied by 2 and the molar mass of 96.2 to get 36.075.</h1>
<p>Then I took that and did this:
(36.075-18.0) /36.075 and got about 0.5, so 50%.
- Am I supposed to do the above subtraction and fraction or do I just do 18/36.075? (In this case it doesn’t matter, but for future problems.)</p>
<p>Also #19, 38, and 39 please!</p>
<p>^This may be too late for you, but SO2 is actually the limiting reagent, not O2.</p>
<p>When i looked through all the MC after finishing, i was sure on about 60 of them, and iffy on the other 15. If i got 75-80% of the Free response, do you guys think i’ll get a 5?</p>
<p>Does anyone know an approximate scale between subject tests and ap tests? For example let’s say I got a 700 on my chem subject test, what would that approximate to as an ap score?</p>

<p>There’s no algorithm that would give you a definitive answer. Some people who did extremely well on the SAT ST get just a 4, while some who do worse may have gotten a 5 (not that a 4is bad). It’s all based upon personal preparation and achievement.</p>
<p>I want to self-study this, does anyone have any tips? I mean, my schedule is really full, so no changes can be made. </p>
<p>Do you think that this is possible to do well on the AP Exam ? And should I talk to the chem teacher about it and get resources? etc.</p>
<p>I self studied this year, so I have an idea of what should be done.</p>
<p>1) Start studying early so you don’t have to cram in so much at the very end. Try to get a good review book (I used PR) and (if possible) a college textbook.</p>
<p>2) Look over past MC questions and FRQs. It helped me feel more confident on the MC and (hopefully) got me some points on the FRQ this year.</p>
<p>Like a lot of people, I thought that the MC was easy, but the FRQs were insanely hard. I think I passed the exam, probably with a 3/4.</p>
<p>I also self-studied, and I can attest to what gatorboy stated above. To my disadvantage, I only started truly focusing on chemistry in early April, so by the time I reached the more extensive chapters like acids/bases and equilibrium, I was insanely rushed for time (I was first learning electrochemistry the day right before the test, lol).</p>
<p>And definitely, looking over past questions helped. Even though I only got through all FRQs from 2008-2010, seeing the questions helped me better understand what topics I should focus on (i.e., whether Ka/Kb or Ksp would show up, or that reaction rates was surprisingly common). Furthermore, I know that the 2002 MC is posted online, and at the same time a link to the 2008 MC (which is fairly well hidden on Google :P) is posted somewhere in this thread (sorry but I can’t be bothered to find it :/)</p>
<p>Anyways, good luck with your studies! :)</p>
<p>Half a month more! XD who’s going to call july 1 to see what they got? I don’t want to be the first one.</p>
<p>Oh I’m gonna call for sure. So glad the wait is almost over. And the AP Chem grading ends this Saturday too!</p>
<p>Lol, I’m going to be out of the country, so I might as well as wait a few more days instead of paying for a long distance call that could potentially ruin my summer.</p>
<p>We should try out some organic chemistry questions while we wait. </p>
<p>What do you all think?</p>
<p>Our final exam for AP Chem was over organic chemistry. And we had to produce an organic product. I made aspirin.</p>
<p>The crazy thing is, I won’t take the credit even if I get a 5…but I want one so bad!</p>
<p>My final is a 2 hour and 30 minute written paper. Wish I could just make an organic product.</p>
<p>Okay, here goes an organic chemistry question! I took it from a Hong Kong A Level Exam paper which is supposedly really hard…</p>
<p>An aqueous solution of benzenediazonium chloride is heated, from which a solid, which is soluble in dilute NaOH is obtained. Suggest a structure for the solid obtained and account for its solubility in dilute NaOH.</p>
<p>Ughh I really hope I got a 5 or at least a 4, I would be utterly disappointed if I got anything lower… Nervous!</p>
<p>My chemistry final was so much easier than the AP exam although my teacher had said that it would be like a mock AP test (final included acids and bases, buffers, galvanic cells, stoichiometry, organic, equation writing, and a mix of other stuff that I can’t remember right now). I somehow manage to score a 99% on it, though I’d doubt my actual AP exam score to be anywhere near that XD</p>
<p>I’d rather have taken an actual test. I had to do a 12 minute presentation over the product and write a 9 page lab report. She was like,</p>
<p>“Well, I think it would be kind of unfair to retest you over something you were already tested over.” </p>
<p>I spent about 5 hours making the aspirin and 6-7 hours writing my lab report and making the presentation.</p>
<p>Moral of the story–always opt for the actual final. Doing an alternative project is actually harder if you are confident with your knowledge.</p>
