<p>Has anyone noticed that on the practice question for the math placement exam that the answer key is wrong on several questions? For example, it gives [-1,1) as the answer to a definite integral. Am I missing something?</p>
<p>Wow, that's really weird!</p>
<p>wow...i didn;t even take it yet lol o.O</p>
<p>At least I think it's wrong. I'm sort of scared to take the test now because I might get a perfect score but the key might suggest remedial.</p>
<p>If there's a problem w/ the answer key (and I suppose there is, or at least it looks that way) Hopkins will find out about it. Don't worry. Major colleges don't let little mistakes like that happen.</p>
<p>I saw that too! I took them to my math teacher, who couldn't find a way to get the answers on the answer key...
Which errors did you find? I found errors on #4, #10, #15, and #16.</p>
<p>Wait -- the [-1,1) should be one of the answer choices for the convergence of a series. That's #14 - B. Which number problem are you referring to?</p>
<p>I contacted Richard Brown is does the undergraduate advising in the math department. He said that there are indeed errors but he said not to worry. I believe there are errors on 4, 14, 15, and 16. I might be forgetting one.</p>
<p>Since we were allowed to use a calculator on this exam, did anyone find themselves using fnInt and nDeriv a lot? I did, and I think the placement the exam recommended was thus inaccurate for my case. Did others here feel similarly?</p>
<p>Not necessarily. There were very few questions that I relied on the calculator for (finding the arclength of that parametric for example). I mostly just did the work by hand and checked with a calculator. There was one question that I think may have a typo but other than that, it was fine. It told me I should take 201, 202, or 211, which is what I was going to take anyway.</p>
