Hello all,

I took the DAT on September 19th of this year, and during the testing session I saw one problem on the organic chemistry section and one problem on the quantitative reasoning section that may have been errors. After reworking the problems and looking up answers for over a month now, I am convinced that these were genuine errors in the test.

I understand that some of you may think that one or two errors are not all that important, but an extra correct answer may bump my organic chemistry score up by several points, which I believe is very significant, and it also is unfair to those of us who studied for months on this exam.

So my question is, is there anyone I can contact and report these problems to so that they may identify whether they are genuine errors or not?
 
I think Beaver means fishing for extra marks. Like in University you can sir during office hours and state your case. They will hear you out, and make a judgment. With the DAT, the process would be a lot more 0paque, and difficult to accomplish.

Right, but at university sometimes there is an ambiguity in the answer choices, and one person may believe that one answer is correct, while the professor may have a different view.

The errors I am speaking of have no such ambiguity; they are incontrovertible errors which I believe would be identified as such by any competent organic chemist or mathematician.

I would personally just get it over with if you scored well on your DAT.
Why go through such a long hassle if you did well.
And if you didn't do well, I don't think those 2 questions will significantly change your scores.
Significant change in number of scores over just a few questions usually occur when you score 21+
Just my two cents.

Another Catch-22 "If you did well, then forget it" and "if you didn't do well, then it won't do much." I scored a 22 on the organic chemistry section and a 21 on the QR section; so those 2 questions could be very significant, don't you think? My GPA is not not as high as other members on here, so a higher DAT will certainly improve my chances. And honestly, how much longer is ADA going to produce tests with errors? The 2009 version of the exam was notoriously fraught with errors, and if no one says anything they are unlikely to change.

No, I do not.

It's also incredibly unlikely that the ADEA will go back and re-score your exam due to these errors. Most likely they will remove or modify the questions for future exams in the event you turn out to be correct. The DAT has certainly had mistakes in it before, but I've never once heard of a re-scoring due to these mistakes. The only time I've seen someone's DAT score change was the guy whose math section came out as a 1 or a 2 due to a testing center error not taking his answer input.
 
No, I do not.

Well I disagree; a 22 on the organic chemistry section would suggest that my OC score would increase up to 25 or so, and my QR perhaps 23. That would raise my AA to a 24 and TS to a 25, so that is very significant. That is a difference between a 14.3 and a 13.8 on the modified San Antonio Formula, and a 36.2 and a 33.7 before the interview with the UNLV formula.

Are you aware of how many errors were present on the 2009 exam? Do you really believe all those errors were factored into one's exam score?
 
There was a typo on my DAT, but nothing was significant though. So an error is possible. If you miss only one question, your score can possibly go down from 30 to 25 in one section and thus greatly affects your TS and AA.

There definitely was an error on my organic chemistry section that I would have easily gotten correct, and could have shot my 22 (on that section) up to a 24 or higher. It really doesn't make sense how I would catch an error on my first time taking the exam (and I finished the science section with about 30 minutes remaining) while the ADA test designers, who have millions of dollars to invest on the exam and a seemingly unlimited amount of time to review it, wouldn't.

I sympathize with you. You're right, there's no excuse for them to get it wrong. However, correct me if I'm wrong, isn't it possible that if there was an error and they saw that many people got the question wrong, they'll review it and void the question? At least, that's how I can see it happening ideally but not necessarily in reality.

Even if they do not do anything about the error, I think it's important for us to take a stand. What do we pay $415 apiece for if we can't even get an error-free test? How difficult would it be for the ADA to have multiple scientists independently take the exam and report any errors they find?

Give it a try, let us know what happens. However, even if you're correct I think you're going to have an uphill battle. Good luck though!

The scale on the DAT is never that unforgiving. You would certainly never jump from a 30 to a 25. That's 2-3 questions incorrect.

Well I disagree; a 22 on the organic chemistry section would suggest that my OC score would increase up to 25 or so

You would go up to a 23. The scale does not jump from 22 to 25. It is only at the very high end (one question wrong) that you can see a drop of 2-3 points.

"The DAT is scored on a scale of 1 30, but it is not a linear scoring system. Your score is based on the number of questions you answered correctly in comparison to others who answered those questions correctly in the past and then calculated through some unknown formula. It is possible that one person could answer only one question wrong and get a 25 for that section, while another person who also only got one question wrong on the same section but a different set of questions receives a 28 for that section. Also, a 20 on a section does not mean you answered one third of the questions incorrectly in fact you may have answered 90% of the questions correctly."

The formula is based on the percentage of students answering those problems correctly in the past, and therefore can change every year. You have no way of knowing that my scaled score would only increase by 1 point, and all, or almost all, of the evidence suggests otherwise.

For example, on the 2007 ADA practice test, there was no scaled score of "22" on the organic chemistry section, but a 23 corresponded to 27 problems correct, and a 21 with 26 problems answered correctly. In both cases, raising the number of questions answered correctly by one raises one's score by two points. A score in the low twenties (i.e. a 22) corresponds to answering almost all of the problems on that section correctly. It is likely I only missed one (perhaps two) problems on the general chemistry and biologys section of the exam, and perhaps 3 on the organic chemistry section (two if you disregard the error on the exam).

1. The site you quoted is not an official source and the only point they were making was that the number wrong can vary to scaled score based on your version of the test. There is no variance that drops your score from 30 to a 25 off a single question. Perhaps it is reassuring to tell yourself this to believe you did better than your score reflects because you were just "one question away" from a really high score. You weren't.

2. You just quoted a 2 point jump off a scale and somehow concluded off that you only missed one or two questions which is just you pulling numbers out of your ass that your actual score does not reflect. You think you did better than you actually performed, but making up invalid theories about the DAT scale doesn't change your actual performance. You are literally just speculating with no evidence behind it. No released scale provides the scores you got off of 1-2 questions wrong, or even close to it.

I'll reiterate: it is far more likely that you were wrong than it is the DAT had multiple mistakes that would magically improve your score to a significantly high one. Your score is not going to be changed regardless so daydreaming about it is not productive. Very few people are capable of doing exceptionally well (27+ AA) on the DAT and you simply weren't one of them.

This entire thread reads like you trying to cope for not doing as well as you wanted on the DAT.

this guy tells it like it is. 99.9% of the people here will agree with @PlasmaMembrane. he's like that guy who tells you you're fat but you still think you're not fat, so you just wear the dress that's 10 sizes too small. #noragrets

So that website is not an official source but you are? How about the 2007 ADA scaled scores then:

1 question wrong on general chemistry dropped the scaled score down to 25 and one question wrong on biology dropped the scaled score down to 26. So again, you are wrong, and the pompous manner in which you've written does not give you any credibility in my mind's eye.

And how does the 2009 practice test compare:

upload_2015-10-15_13-10-37.png


And what do you have it? 27 questions correct out of 30 gives a 22, and 28 right gives a 24 on the organic chemistry section. And guess what, 1 problem wrong on the general chemistry section lowered one's score to a 26. So even according to the 2009 scale, I got 2 questions wrong on biology, 1 on general chemistry, and 3 wrong on organic chemistry (2 without the error).

And that leads me to ask, why do you care so much about how well I did? What's more important is that there is an exam that pre-dental students take every year which will be a major factor in determining whether they will go to dental school or not, and all you seemed to be cared about is telling me that I'm "not as smart as I think I am," which only suggests to me that you have self-esteem issues over your own perceived intelligence, or lack thereof.

Weren't you the one who claimed that my 22 would go up to a 23 if I had one more problem right, and you have the temerity to accuse me of "pulling numbers out of my ass" when I cited Kaplan, the 2007 and 2009 practice test? Smh the nerve of some people...

You must have missed the part of the thread where I said that I do not mind if my scores were changed or not, but only am frustrated that I have to pay $415 for an exam that will determine my future with the knowledge that there are errors no it. You have shown that you have no credibility whatsoever, so it would be best if you left this thread alone... It really amazes me the number of people over the age of 18 who are unwilling to admit that they're wrong, but we will see how far you will get in life with that attitude.

this is you btw... so just shut up (pls).

PS. kaplan sucks, my friend works for them and she says their DAT material and info is out of date and garbage lol idk why she still works for them.
also the 2007 and 2009 tests are not good predicators for determine your score in 2015 (8 and 6 years OLD, respectively)........ I would say it's good to practice those questions but I would not rely on those grading scales.
if you wanna see the scale for this year, maybe just wait like 7 years. If you have a decent DAT score overall (21+) then you will be fine so don't sweat bud
