<p>I got raped by both those tests. Mechanics last FRQ was so ungodly hard. I am so dissapointed, I hadn’t the slightest idea of how to relate rotational and translational, simultaneously, as a function of time. I understand what would happen, but I don’t know what equations, methods, etc to use at all…
E&M mc was super easy compared to Mech. The E&M frqs seemed like they would have been easy had I studied more… All familiar topics but all detailed just past the extent to which I knew them… Time was a killer for me too, as always, but ESPECIALLY on these two exams.</p>
<p>E&M:
Totally killed. Would be super surprised if I didn’t get a 5 since there isn’t a single part of FRQ or a single MC I didn’t know how to do.</p>
<p>Mechanics:
Totally failed. I left like 8 answers blank in the MC because I marked them and didn’t have time to go back to them when the proctor called time. For the FRQ, I am confident about all of number 1 except the last part (the graph one), and for number 2 I BSed the second to last part… And FRQ 3 lol… I am sure I got a and b correct but prob got 0 points on the next three parts.</p>
<p>Hoping for a good mechanics curve.</p>
<p>The FRQs for E&M were very straightforward and easy for the most part IMO… MC wasn’t too bad although I did get a lot of B’s. Mechanics was ok, expecting a 4 there and 5 on E&M.</p>
<p>I got a lot of "B"s too :D</p>
<p>Multiple choice felt pretty moderate. I think I only missed 6 to 8 or so. FRQ was definitely harder than past years but I felt ok about 1 and 2 (maybe 10 and 12) and the first couple parts of 3 weren’t terrible, plus partial credit on CDE might be about 6 on 3. That would make a 5 with a fair amount of leeway.</p>
<p>Is self studying E&M hard? I just self-studied Mech and took it (expecting a 5) and I think I’ll do E&M next year.</p>
<p>I personally think self-studying for mechanics would be a lot easier than self-studying E&M just because a lot of the concepts and such make more sense and can be visualized and such. I also fine mechanics easier in general, though, which seems to be rare</p>
<p>3mg (10char)</p>
<p>For mechanics, my proctor didn’t give us any warning of time, and I couldn’t see a clock… and left 12 blank. Holy crap. The only reason I’m not /completely/ freaking out is that I think I did decent on the FRQ and of the 23 questions I answered, I was extremely confident they were right…</p>
<p>E&M was another story. My brain shut down entirely.</p>
<p>I think i did so poorly that I would be happy with a 3. With the difficulty on the Mechanics test, what do you all think you need to get a 3, percentage wise? I only took Mechanics.</p>
<p>wow…
the FRQ’s made me go almost nuts for the mechanics section.
I have practiced most FRQ’s from 1990s to present, and by far this year was the toughest one!
I hope they have mercy on us with a very generous curve this year.
I came in to the test expecting a 4 but most likely a 5.
Now my dream is crushed… :(</p>
<p>I got a lot of D in MECH MC.</p>
<p>yeah also a lot of A</p>
<p>I will proceed to cry myself to sleep… The MC for both were a breeze, but the last questions on each FRQ… Makes me want to cry…</p>
<p>@Desafinado: Are you taking MECH or EM ? Did you get a lot of D also ?</p>
<p>I think for Mech 2, you could have done a number of different scenarios. It’s all about making sure you don’t skip important parts, include all of the different things you would need and explain why and how.</p>
<p>Yes a lot of A and D on mech</p>
<p>who figured out how to do question 1 for mech?
how did u guys do it?</p>
<p>For mech frq 1 (I could be wrong) it just looked like a -sin graph. I said v=-.7sin(t) where .7 was the adjustment based off of the graph shown. So then x was the antiderivitive making it x(t)=.7cos(t) … I think. But I’m sure there was some more-correct way to do it. Then also f/m=a=dv/dt helped. And then kx/m=(d/dt)v so somehow the .7 had something to do with some part of the period or frequency equation for the later parts of the question. I’m not sure though, just my guess.</p>
<p>Amplitude was 1.6; period was 0.7. That means the equation was v(t) = 1.6<em>sin(t/(0.35</em>pi))</p>
