<p>@Davidthefat: That and conservation of energy. Makes up like 40% of the questions.</p>
<p>In case anyone’s still here: I just finished taking my first PR practice test MC, and I got 33/70. <em>facepalm</em>. I think it’s pretty much safe to say I’m not going to get a 5 right? </p>
<p>If I manage to get around that tmw and maybe a 30/80 on the FRQ, can I still get at least a 3??</p>
<p>Last year, on my first released physics test, I got around that score. I ended up getting a 4 on the real thing and 750 on the sat subject exams. That’s without any additional studying and terrible FRQ.</p>
<p>Thanks for replying!</p>
<p>What equations should we memorize? Kinematics, Work, Forces, Pressure, Density, Energy, Wavelength, anything else?</p>

<p>Tommorow’s test will be a breeze. Worked over 30 years worth of Free Responses since my teacher was part of the Test Committee. Multiple Choice is basically a joke if you understand the physics; the only problem will be making sure you got the algebra right xD. You don’t really need to memorize formulas, except the variations in which one could use them for specific problems. Oh yeah, my teacher said," Don’t forget to bring a ruler because I won’t have any." He was probably inferring some Optics FRQ -_-, not my favorite subject really. It’s too bad they don’t cover special relativity or quantum mechanics, those frqs were easy lol… Well good luck everyone! Most annoying FRQS were some of the lab ones I did, waaaay too detailed <em>sob</em>.</p>
<p>Hey Arion231 you seem really confident could you help me understand this problem <a href=“http://i.imgur.com/pMtN5.png[/url]”>http://i.imgur.com/pMtN5.png</a></p>
<p>OMG last night I was dreaming as well about physics… SO SAD.</p>
<p>^Haha, the morning before the AP Chem exam, I was dreaming about Chem…</p>
<p>My life is so sad.</p>
<p>I actually feel really good about this exam tomorrow. I am confident I can get at least a 4, but getting a 5 would be awesome!</p>
<p>Can someone do a quick summation of all the laws we need to know for the mc</p>
<p>Can someone explain 2009, number 19? Please?!</p>
<p>good luck on the test today :)</p>
<p>Quick question: in the formula Xm=m<em>wavelength</em>L/D, what does m stand for?</p>
<p>m is called the order number; m can be seen as the nth bright fringe from the middle. The middle one is the 0th order, the one left and right of it is the ± 1th fringe and goes one and on…</p>
<p>Single Slit predicts DARK SPOTS while Double Slit and diffraction gratings predict LIGHT SPOTS.</p>
<p>A little more than 2 hours away from the test for me! Good luck everyone</p>
<p>I am so damn close to scoring 5’s on the practice tests I’ve been taking.
I’m like <5 measly points away. </p>
<p>Anyway, I hope the test is as easy as the BC test was! But that’s just wishful thinking.</p>
<p>Good luck everyone 2 more hours and it’s showtime.</p>
