<p>Thanks!</p>
<p>@emblem101 or anyone else that knows:</p>
<p>What have the past finalist cutoffs been for the past 3-4 years or so?</p>
<p>@ upsilon</p>
<p>You can check the threads from previous years for more information but last yearās cutoff was around 56% and the year before it was around 75%.</p>
<p>Just took the semi and as emblem101 said it was much more straight forward than semis of the past. No repeat questions, but one that was similar. I only encountered 3 very difficult questions the rest were mildly hard or easy, but Iāll have to see how I do. It would not be the first time that i overestimated my results.</p>
<p>After taking the semis I felt I should have spent more time on biochem and anatomy. After C & R studying what other textbooks do you think would have helped you to ace this test?</p>
<p>@opinion If that question was directed at me, all I read was Campbellās. Iām not sure ace is the correct word. Maybe it is my mind that is in denial or I had some mental reaction that made me think I did better than I actually did. Weāll see next month.</p>
<p>This test was far easier and covered much less obscure stuff than previous semisā¦ consequently I feel like I studied the wrong (obscure) stuff, it felt more like a harder open exam than a semis test, especially at the beginning. That being said, the cutoff should be pretty high this year, especially knowing that there will be at least 20 people who donāt make dumb mistakes.</p>
<p>when does the testing window end so we can discuss? </p>
<p>and like previously said by emblem101 Iād expect cutoff to be close to 80% this year.</p>
<p>The testing window closes on March 23. After thatā¦ we can discuss. Anybody else encounter a lot of biochem? There was less plant qās that i was expecting.</p>
<p>Gah I ran out of time (didnāt even put random answers for the last few pages). I was stressed out because I was late getting to the room and yeah. I guessed on most of them. Itās funny, because the second Part C question was exactly what we had been doing in AP BioĀwe even have a test next weekĀbut I hadnāt studied or read the chapters in Campbells for it. The hardest ones for me were ALL the human bio stuff because thatās what we do at the <em>end</em> of the year. I am too busy to have read it all on my own. Anyway, I canāt wait to see my final score. Hopefully above a 50%? Haha. Iām especially curious about Part C. Do they give you a score breakdown?</p>
<p>@Melkor</p>
<p>I am still not sure if the list of books in the beginning of this thread is really necessary if you had a sound knowledge of chemistry ( which I donāt have yet) and memorized all charts and figures in C & R. The only place where I felt studying extra might have helped me was in anatomy. I wish they would break up the results into honors/high honors etc. like they do in chem olympiad. That way, if you donāt make the top 20 which is a ridiculous cut from 640 you donāt feel like you wasted all your time on this one exam.</p>
<p>@opinion</p>
<p>I think all the biochemistry I needed was in Campbellās.</p>
<p>We can discuss questions now, right?</p>
<p>I donāt whet why we couldnāt. The last day of testing was the 22nd and the mailing deadline was the 23rd.</p>
<p>In that case, Iāll start</p>
<p>Which of the following amino acids is LEAST likely to be found in the TM region of a GPCR protein: I put PROLINE</p>
<p>Which of the following synthetic nucleotides is MOST likely to form 3 hydrogen bonds with another given synthetic nucleotide: I put the one with an amine group and an amide group</p>
<p>I think I screwed up the lac operon questions, but not sure. </p>
<p>What percentage of human body heat is generated from muscle? I put 85% [Anatomy</a> & Physiology Study Questions](<a href=āhttp://www.gwc.maricopa.edu/class/bio201/jcastu54.htm]Anatomyā>http://www.gwc.maricopa.edu/class/bio201/jcastu54.htm) </p>
<p>The urine question was 1.8 L, I thought</p>
<p>The answer to the curare question was Flaccid Paralysis, I thought</p>
<p>Bacteria use FLAGELLIN for motion</p>
<p>Possible causes of Klinefelterās Syndrome were: Errors in Meiosis II of Oogenesis and Meiosis II of Spermatogenesis? Not sure about this question.</p>
<p>@beandelphiki
- I donāt remember all the choices exactly, but I remember the answer to the GPCR amino acid question was really obvious when I saw it, so I think there was a polar amino acid in there that I chose. Not 100% sure though, proline would make sense otherwise as it disrupts helical domains (except in collagen where it exists as hydroxyproline :D)</p>
<ul>
<li><p>I think I screwed up the lac operon questions as well, it seemed like multiple choices would work for some of them.</p></li>
<li><p>I donāt remember the one about synthetic nucleotides structurally, but it was choice B</p></li>
<li><p>I felt 1.8 L was the only one that made sense, and multiple websites also confirm 1-2 L per day.</p></li>
<li><p>I missed the curare question, wikipedia says it causes āasphyxiation owing to the inability of the victimās respiratory muscles to contract.ā So I guess flaccid paralysis works.</p></li>
<li><p>I agree with Flagellin, I missed the flagella structure question on open so I made sure to keep an eye out for similar questions.</p></li>
</ul>
<p>Now I have a few questions/answers of my own:
- For the diagram of wood, I put LEFT as you had to move in the direction of early wood to late wood.</p>
<p>-After acclimating to a higher altitude for a week, I figured alveolar pO2 would drop because the atmospheric pO2 drops, but I have no idea</p>
<p>-On the diagram of the root, I put ZONE OF MATURATION as root hairs appear then (Ravenās diagrams ftw)</p>
<p>-Missed horseshoe crabs, theyāre CHELICERIFORMS (I remembered them on the same page as spiders but second guessed myself :()</p>
<p>-On the last question, A C and E were herbaceous eudicots, but I didnāt put C (marigolds) because I was unsure</p>
<p>-For tracing the path of sperm during fertilization, it was 1) seminiferous tubules 2) epididymis 3) vas deferens 4) urethra 5) āovule ductsā or whatever they called fallopian tubules 6) uterus. This question was VERY dubious though, because fertilization occurs in the fallopian tubes AFTER sperm passes through the uterus before the fertilized egg RETURNS to the uterus. I hope they throw this question out (if I got it wrong :D)</p>
<p>-For the free response, I put anterior pituitary because it was messing with Growth Hormone, Luteinizing Hormone, and Follicle Stimulating Hormone. As a cure I also suggested the patient go on estrogen and progesterone therapy. For the comparative analysis part of the free response, I donāt think campbellās covere much of the stuff about arthropods as well as they did for annelids, so I only had 1 and a half columns full lol</p>
<p>Also, does anyone remember the true/false for the biome characteristics? I didnāt remember those well and only put one falseā¦</p>
<p>More and more I think I got destroyed (especially considering how I left the probability/calculation questions till the end and then ran into time trouble >.<) I can only hope at this point that everyone made dumb mistakes, but that never happens haha. If I remember any more Iāll post them here. And if anyone agrees with me on the fertilzation question, can you tell how to report dubious questions from the tests to CEE?</p>
<p>@ramboacid</p>
<p>The operon questions asked for multiple answers</p>
<p>I got all of those answers, except Kleinfelter and the muscle heat production one which I know I missed. 85% is correct. Kleinfelter I put Meiosis I instead of Meiosis II. And Lac operon questions had multiple answers, which is why they are worth 2 points.</p>
<p>I missed the tree trap question too, mixed up right and left
ā¦</p>
<p>You cannot discuss answers yet! Last year there were issues and people were disqualified because they discussed before the answers were released. Some people may not have taken it!</p>
<p>@Skater29: When are we allowed to discuss?</p>
