<p>WOOT I got 800 
ON BIO M MWUAAHAHAHA One night of cramming WOOHOO but I failed my world history T__T</p>
<p>Yayyyy daesung, your wish came true xD I remember you fretting over it a lot a few weeks ago xD</p>
<p>800 on Bio M!!! I omitted 2 of the questions.</p>
<p>Pretty excited about it.</p>
<p>got a 730 on Bio-EâŠsigh</p>
<p>Guys, the starfish dino bird question is wrong ⊠youâve arranged them in the WRONG order!!!</p>
<p>^Wait, how did you figure that out?</p>
<p>[Timeline</a> of evolutionary history of life - Wikipedia, the free encyclopedia](<a href=âhttp://en.wikipedia.org/wiki/Timeline_of_evolutionary_history_of_life]Timelineâ>Timeline of the evolutionary history of life - Wikipedia)</p>
<p>Ma = million years ago</p>
<p>Starfish: âmodern starfishâ appear 190 Ma
Shark: 363 Ma
Dinosaurs: earliest dinosaurs appear 225 Ma
Bird: a possible ancestor to the birds appears 155 Ma.
Whale: 55 Ma</p>
<p>In order from earliest to latest:</p>
<p>Shark -> Dino -> Starfish -> Bird -> Whale</p>
<p>So you guys are COMPLETELY WRONG!! You guys put</p>
<p>starfish, shark, dinosaur, bird, whale </p>
<p>OR</p>
<p>190 Ma, 363 Ma, 225 Ma, 155 Ma, 55 Ma </p>
<p>Good job guys. 190 million years ago is totally earlier than 363 million years ago. #mathfail</p>
<p>^Stop being a know-it-all jerk. SAT/AP Biology does not require you to know the exact time sea stars (not starfish) evolved. They want you to see that it is an echinoderm and echinoderms existed BEFORE any type of vertebrate.
Sea Star, Shark, Dinosaur, Bird, Whale.
Echinoderm, chondrichthyes, Reptilia, Aves, Mammalia.</p>
<p>
</p>
<p>I read the entire thread. Donât change the question. Nobody mentioned sea stars, only starfish.</p>
<p>
</p>
<p>Really? Where does it say that echinoderms existed before any type of vertebrate?</p>
<p>^Sea stars are starfish?
and lanayru is right, the question wasnât testing your ability to memorize dates when certain animals appeared, it was asking about your knowledge of evolutionary progression. Echinoderms are less advanced than chordates so they came first. Then sharks and dinosaurs and birds and whales.</p>
<p>Also, whatâs the point of this argument? Scores are already out</p>
<p>Actually, IceQube, the answers for that question only included four organisms each. So you didnât specifically need to know each organismâs appearance on earth. Itâs hard to explain but there were five organisms in the diagram. Each answer choice included only FOUR organisms. That means it was easier to choose the correct answer by knowing the general evolutionary progression. I totally agree with Lanayru and AstroBlue.</p>
<p>Also, starfish and sea stars are the same organismâŠand also, none of the names were even mentioned! There were only pictures of organisms (in the diagram).</p>
<p>Sea stars = starfish. Iâm just clarifying because the scientific community or whatever is transitioning to more accurate common names. See also sea jelly = jellyfish âD</p>
<p>^also agreed that it presented 5 pictures and answer choices only ordered 4 of the 5 pictures.</p>
<p>5 wrong and an 800. Interesting curve this year.</p>
<p>^ Which five? You might have gotten one or two of them right. Regardless, 800 was still good enough for 97th percentile.</p>
<p>Haha I know right?? I got 2 wrong for SURE, and skipped two, got an 800 
whatever, Iâm not complaining!</p>
<p>I got a 730 on Bio E. I couldâve done better, though. Do you guys think this is good enough for top colleges?</p>
