Hi. I recently took the ADA 2009 Sample test and I came across some mistakes that were not included in the correction sheet that came with it. If anyone has time, can you please confirm if these are mistakes or not?
I am not going to post the question because I don't know if it violates copyright or not. So if you have a copy of the 2009 ADA exam please check for me please.
For the natural science section (These are questions that I believe to have mistakes not listed on the correction sheet).
#14 It says it suppose to be D) Bicarbonate. Shouldn't it be C) Phosphate?
#90 None of the answer choices has 7 carbons, but in the question it says the answer should have 7 carbons. So I'm thinking the whole question is an error.
#97 It says the answer is D) Identical. Shouldn't it be A) Constitutional isomers
I realize this is an old post but having just taken the 2009 ADA test, I had some comments to add.
I won't post entire questions/answers, just fragments, though I think their policy on this exam is simply about making money considering the questions are all retired.
Biology: (Everything checked against Campbell's)
#14: As mentioned above, this question asks about buffers, and the answer is clearly phosphate buffer. Ironically, there is no mention of the phosphate buffer in Campbell's, I only knew this from Destroyer/google search/wikipedia.
#16: Forgot to add this: specific protein involved in receptor-mediated endocytosis? Yeah, not found in Campbell's, hope all of you relying heavily on wikipedia. No wonder people are balking at some of the bio questions on the real thing, if they're like this one.
#24: This question talks about a biome, the answer they say is the arctic tundra; the problem is that the question combines these two descriptors: permafrost and large variation in annual temperatures. None of the biology sources I have ever suggest that the arctic tundra has large variations in temperature annually. Basically this seems to be some kind of mix up between the Taiga (which does have large variations in annual temperatures) and Arctic Tundra (permafrost).
Organic Chemistry:
#82: Seriously, we need to know this? (Personally I don't remember learning about petroleum in orgo, though perhaps my memory is just fuzzy); not a huge complaint, just found the question to be a bit odd.
#90: Agreed with the OP, this question is completely defunct.
#91: Had to google this one, not sure how to word it without giving too much information (regarded lab techniques and non-volatile/volatile substances).
#97: Agreed with the OP as well, I stared at these two molecules for quite some time trying to figure out how they were identical and not constitutional. *shrug*
#99: This question is flat out weird, and the answer doesn't make sense, there are seemingly correct answer choices, but the answer key gives an answer that doesn't make sense, probably a typo. I googled this one and actually hit a post here on SDN from 2010 which confirmed my thoughts.
#100: Strange IUPAC naming thing, never saw it before, though I'm sure someone has (involves the greek lower-case Lambda).
