<p>Also the question about lysine and leucine and ketogenic amino acids in general was more than slightly obscure though it did have only one correct answer.</p>

<p>The two I was talking about earlier were Gluconeogenesis and Steroid Synthesis. According to Lehninger’s Prciniples of Biochemistry gluconeogenesis starts in the mitochondria and ends in the cytosol so both answers should count. Also according to some Stanford lecture notes and some other sources the specific reaction that uses the mitochondrial matrix is "Conversion of pyruvate to phosphoenolpyruvate occurs by a combination of two reactions. In the first reaction, pyruvate is converted to oxaloacetate by pyruvate carboxlyase. This reaction takes place in the mitochondrial matrix and is also used to generate oxaloacetate as an intermediate in the TCA cycle.</p>

<p>For steroid synthesis the answer could be either mitochondrion or smooth endoplasmic reticulum. According to wikipedia, “The rate-limiting step of steroid synthesis is the conversion of cholesterol to pregnenolone, which occurs inside the mitochondrion”. However it goes on to say that most of the process occurs in the smooth ER.</p>

<p>I don’t know if you have any say over the grading but if you could mention this to the people at CEE it would be appreciated.</p>
<p>I’m just interested in how you guys think questions could be better worded. </p>
<p>IBO tests are written by different people each year. You have to be prepared to encounter unfamiliar nomenclature and unfamiliar techniques. Also, for IBO you don’t get to complain about the test. Should you find a problem with a question, just answer it as best you can and move on, no use worrying about it. I said this before, being “smarter” than the test doesn’t get credit. Tests will be imperfect, that’s reality. That’s why it’s always “choose the BEST answer”, rather than the right answer. </p>
<p>But yeah, could’ve been better written. Ought to have added something about “the last step in each process”, or ask where the bulk of the reaction takes place or something. </p>
<p>Okay, more precision, good. </p>
<p>Grasshopper legs was a throwback to 2005. And again, did part B directions really not mention multiple answers?</p>
<p>Part B directions definitely didn’t mention anything about multiple answers. All it said was that the questions were going to be worth 2 points and that there might be different type of questions: multiple choices, matching, roman numeral, etc.</p>
<p>@cadaeibfed what do you think about the neuron question that some of us believe had two correct answers?</p>
<p>Whil waiting for the result, I am trying to read a textbook on Anatomy & Physiology. What kind of A&P textbook do you recommend (I like the “Essential” one)?</p>
<p>Also I am kind of confused as to if it is safe to metion “nerves” as neurons, as I heard that nerves generally describe bundles of myelinated axons. I followed Campbell vocabulary, but do we just have to memorize all synonyms of biological vocabulary?</p>
<p>Part B instructions did not contain any information about multiple answers. I remember because I checked several times in my confusion and still didn’t know what I was supposed to do.</p>
<p>The nerve question seems to have been changed since my latest draft. Therefore, no comment. </p>
<h1>926 - Quoting myself:</h1>
<p>IBO tests are written by different people each year. You have to be prepared to encounter unfamiliar nomenclature and unfamiliar techniques.
You should be aware of different terminology and different usages, don’t expect any standard.</p>
<p>Well, I’ve just received the “under consideration” e-mail from USABO (which was /quite/ a shock, to say the least…). I’m not entirely sure what that means, but the wheels are officially in motion. =/</p>
<p>congrats!! That’s a bit strange to me though cuz I called CEE today and they said they are sending out the emails tomorrow…well anyways congrats and good luck to y’all.</p>
<p>Hey guys! I got an email!!! It was sent at 4 o’clock today. Good luck all!</p>
<p>So did I! Congratulations to everyone who made it (and good luck to those who haven’t yet gotten an email)!</p>
<p>Did every finalist get notified as of now?</p>
<p>@tigertwist: did your email say that you were under consideration or that you definitely made it?</p>
<p>the emails say that you are under consideration</p>
<p>see everyone at purdue! i’m so excited</p>
<p>Wait, I thought it was too early to assume that everyone who received an e-mail is in… isn’t…it?</p>
<p>Not that I wouldn’t love being wrong about that.</p>
<p>Yeah, have all finalists been notified already? I think I’m screwed but I really need a confirmation of being screwed before I can get some rest.</p>
<p>ARGHHHHHHHHHHHH I’m dying here right now.</p>
<p>Well I missed finals again but at least I got questbridge prep scholar and fein fellow. I guess that I should not have expected anything since I only studied like an hour per week. Congrats to those that made it.</p>
<p>Judging from what happened last year, I believe the only way they would send out more emails is if one of the selected finalists declined to go.</p>
<p>asteraceae: Wait, really? I had thought that last year they sent out like 30-40 of these… or, do you mean, if someone said they could go via the e-mail, were selected as a finalist, and then backed out for some reason?</p>
