<p>cause if what you posted are right, then you absolutely molested that test. damn if i had gotten some sleep the night before and not been so nervous, i woulda kicked ass too. maybe ill see you at USABO if i get through.</p>

<p>everybody post your score once they come in.</p>

42

<p>Wow… pea_sea04, I’m amazed at your recall of that many questions. Haha, I logged on to post the handful that I remembered, but you already had those covered and a whole lot more too.</p>

43

<p>oh wow…of the 30 questions and answers posted, my percentage stands at about 50, maybe 60%</p>

44

<p>hah, last year i got to semifinals. my open score was really low too, about 27. i hardly studied. </p>

<p>and those ones i posted are right. i checked them with my bio teacher.</p>

45

<p>i don’t have all of the ones i posted right. i remembered the right answer in damned retrospect. i think i got about 2 right for every one wrong.</p>

46

<p>i think we should just pray that cee misscores everyone else’s test, so we ccers all pass.</p>

47

<p>yeah of the ones posted im about 2 right for every one wrong but thats not even very good. im pretty upset cause i have the same thing as pea sea- in retrospect, i knew every damn answer on that whole test. for me it was nerves and not enough sleep but given on any other day and i wouldnt even be second guessing myself. i did well on the ecology/evolution questions, but the oddball questions screwed me over</p>

48

<ol>
<li><p>fish migration
wrong answer</p></li>
<li><p>adaxial surface of leaf
hypodermis</p></li>
</ol>

49

<p>last year the highest score was 45. i refuse to believe that someone did that well without cheating.</p>

50

<p>which is, come to think of it, surprisingly easy. cee sure puts a lot of trust in the teachers. </p>

<p>if my bio wasn’t my ethics teacher as well, i would have convinced her to give me a copy.</p>

51

<p>hah, biomasta. my usabo thread beat yours. my gangzta is greater than yours.</p>

52

<p>lol yeah thats cause i ditched mine! lol, yeah ive contributed a lot of this thread though :). lol, yeah 45/50 is pretty amazing…im sure they had some kind of help, the questions are TOO out there to get that many right. i wonder how the USABO Open Exam questions compare to the IBO Theoretical Exams?</p>

53

<p>if you go on ibo-info.org, you can see a sample of the ibo theoretical exam. they’re pretty similar, but i think they’re a bit easier.</p>

54

<p>hehe, the lowest score was a 2. you could get a higher score if you guessed on all of them. i think his problem was that he actually used his brain.</p>

55

<p>Yeah a 2’s pretty bad…they did some seriously wrong thinking. lol</p>

56

<p>there was one question that really stumped me. </p>

<p>the vertebrae column is (blank) to chordates and (blank) to vertebrates
homologous, analogous
analogous, homologous
primitive, derived
derived, primitive</p>

<p>does anyone know the answer? or even what they’re asking?</p>

57

<p>hmm i put primitive, derived…</p>

58

<p>are you sure about that answer ?</p>

59

<p>ahhh i think i put the same as antemortem, however upon further thought…</p>

60

<p>Okay, so subphylum Vertebrata has a vertebral column. all members of vertebrata have it. not ALL members of chordata, however, have it. since this vertebral column of sorts is UNIQUE to vertebrata, it is a derived character. since only the vertebrata portion of chordata has the vertebral column, the vertebral column is primitive to chordata. so yes, primitive, derived is the correct answer. i finally get a few right. damn. im sticking to this one. lol</p>
