<p>the interval was (b-a)/n</p>
<p>yeah stop everyone.</p>
<p>what raw score do I need for at least a 4?</p>
<p>heh... wow, it's only about 8, but there's been this much posted... i feel inadequate posting what i felt about the exam. </p>
<p>i didn't take the class - just IB Math SL, so i didn't know some stuff. for instance, slope fields ... i think i did ok tho..</p>
<p>was i the only one that thought that the free response was a JOKE and that the MC was a lot harder than the free response? on the one practice exam i took, i got a more or less perfect on the free response and bombed the multiple choice (28/45). i expect the same thing to happen this time - a lot of questions wrong on the mutliple choice (about 10-15) and then a free response to pull me up to a 5. tho i only need a 4 to credit</p>
<p>and then, after i was done my AP exam, I had to take my IB exam 10 minutes later. for a total of 4 hours and 45 minutes of math doom today.</p>
<p>I agree--posting answers isn't a great idea.</p>
<p>possibly an admin could edit out the answers? references to questions indirectly is fine as the same type of questions appear every year, but exact answers..</p>
<p>i tought they said no slope fields on the ab test, but i guess they had it,</p>
<p>"oh no they are going to come and get me and I wont be able to attend Harvard now" wahh!!!!</p>
<p>Well, if you did your homework in Calc throughout the year, this should be easy, or at least easy enouph for a 3. I had to learn a lot of stuff in the last week(a lesson I learned for college I suppose), so Im expecting a 3. The free response was a pain on some of it, they had probably the worst possible FRQ (the ones I least studied on out of my 6 practice exams), so that didnt make me too happy.</p>
<p>^true......</p>
<p>for the tangent line at 108 i divided 108 by 5 and got a remainder of three and figured it would be the same as the tangent at x=3, the slope of which was the y-coordinate on the graph</p>
<p>sound right at all?</p>
<p>if I get 50% right, do I get a 4?</p>
<p>Im pretty sure 54% is a 4, but I do know for a fact 40 points is a 3.</p>
<p>Non calc MC annoyed me
Calc MC was raped by me
Calc FR tickled me
and Non Calc FR was destroyed by me</p>
<p>BTW 40 out of 108 is so rediculously easy to get i would hide my face if i got anything below a 3. Im just playing. Maybe some teachers didnt prep as good as mine cause for me the test was maaaaad easy.</p>
<p>Can anybody tell me how I should calculate the raw scores from the FR and MC sections, please? Thanks :)</p>
<p>in the question with the line tangent to x=108, was the point even differentiable?</p>
<p>It will be ok everyone.</p>
<p>Is it like stats where you multiply MC by 1.25?</p>
<p>I believe it was, becuase they have you that it was a periodic something or other, which I took to mean it just repeats itself and what they had graphed was two of its periods. So, to find g'(x) you had to find f(x) at 108, which I think could be done with the "period" info. If this is wrong I'll feel awfully stupid.</p>
<p>1.2 not 1.25</p>
