<p>@BadGirlsClub I know for 2008 they had a 5 be 65… it varies from year to year. I think this year is questionable though since guessing doesn’t hurt and the MC was considered easier by most.
I bet there will be a ~decent~ curve though, anywhere from 1-5 less than the original ? <-but don’t quote me on this, I’m just taking a guess
Let’s hope the rest of the country did worse than usual so it can elevate our composite scores hehe ^^"</p>
<p>haha I drew a little picture illustrating the underestimate on 5b with lots of arrows pointing “here” and stuff lol</p>
<p>@naokifresh thanks. i really hope i got a 5. the last time my school got a 5 was 4 years ago. and my teacher had high hopes for me to get it. but if not then oh well. i know i definately got a 4 at the least. which is good considering that last year only 3 people got a 3 and 1 got a 4.
plus i only needed a 4 or 5 to get college credit at Rutgers. so im good.</p>
<p>Can someone explain why the meaning of the integral in 2(b) (inside: H(t)dt)) is the average temperature of the tea throughout time = 0 and time = 10?</p>
<p>Since H(t) is in degrees and dt is minutes, why aren’t the units degrees*minutes?</p>
<p>This is because you’re dividing it by 10 minutes (average value: 1/10 minutes times that integral, which is in degrees/minute). The minutes cancel (degrees*minutes/minutes), giving just degrees.</p>
<p>Everyone’s complaining about #5 on the FRQ eating their soul, but I’m pretty sure I got an 8 or 9 on that one. 6 and 4, on the other hand… I totally forgot about the 2x added to the integral, and I had no clue how to get an actual value out of the derivative of a piecewise, let alone find the average value of it altogether. We went over our FRQ’s in class today, and it’s looking like I’ll get a 36-39, so I don’t think I did too badly overall. I thought it would be impossible for me to get a 5, but I’m starting to think I have a good chance now. Just crossing my fingers on the multiple choice. :</p>
<p>yeah the separation of variables part is like a good 4-6 points in itself. I think i got like a 6-8 depending on how lenient they are… i forgot to put the dw/dx for the implicit differentiation part…
but yeah MC will make or break me and i have no idea how I did since i had to guess/half choose many… not good.</p>
<p>My teacher preached, “Anytime you see a graph of f(x) on the essay, write = g’(x) beside it” for the sake of simplifying the concept to those that weren’t too great at calculus. Needless to say, most of my class probably missed problem four haha.</p>
<p>Oh sorry guys for not replying earlier. Before you guys get disappointed and rage at me, I’m telling you its not that big of a deal. Anyone could have done it, and it’s nothing too special. </p>
<p>So the day before the test, I went to bed at around 1 a.m. Then the morning of, I set my alarm to 5. I didn’t want to wake up at all, but I forced myself to. I got online and started to look at the CB’s solutions to past FRQ’s. I don’t know if this is true for every year, but I happened to click on the FRQ’s for 2010. </p>
<p>THE QUESTIONS ARE ALMOST IDENTICAL! ONLY THE NUMBERS ARE DIFFERENT!</p>
<p>When I opened the exam book, I was shocked because I had reviewed how to do all of the FRQ that morning. The questions weren’t in the same order, but they were the same! Just different numbers! Check if you don’t believe me:</p>
<p>@kwokings033:
LOL!! I felt it was important because I almost skipped on doing it, but I realized later that if I didn’t do it, I would have been so screwed for the FRQ.</p>
<p>Oh btw, I also wanted to add that for the question about speed. it was definitely decreasing. I clearly remember reading in PR that if the velocity and acceleration have different signs, then it’s decreasing. If the signs are the same, then it’s increasing.</p>
