<p>Hey everyone! </p>
<p>Yes, there is still an embargo so thoughts only for now :)</p>
<p>I just took the test today, pretty worried...</p>
<p>Good luck everyone!</p>
<p>dude physics was OK. but if every1 found it pretty bad, it guess the curves will do the moderation</p>
<p>i did bad…</p>
<p>well the general level of difficulty was okay…but there were so many questions I kinda knew but wasn’t sure…like, a couple questions in Part A lol</p>
<p>I finished the test at the exact second time was up haha</p>
<p>I was hoping for an 800, now if I score >700, I will be amazed…</p>
<p>when are we allowed to talk about the test itself?</p>
<p>I honestly have no idea how I did. o.o</p>
<p>Overall, i felt the test was easier than the Princeton tests. The questions were a lot more concept-based than the questions in the Princeton tests.</p>
<p>But I did think the “match the graphs” questions were pretty difficult.</p>
<p>yeah, everybody agrees with that i think…crazy match graphs questions…</p>
<p>Yup those graphs… Oh myy and they were towards the beginning so… Kinda threw me off lol</p>
<p>hey embargo lifted! Was the soap film one interference? And the reeraction index one was E, none are sufficient?</p>
<p>I dont think it was interference</p>
<p>and i got n1=n3 for the refraction index</p>
<p>not sure though</p>
<p>ye soap was interference.</p>
<p>The only one that troubled me was that stupid 1st of thermodynamics question!</p>
<p>***? Is it the energy can neither be created nor destroyed crap? or the E=q+w? I put both but I think it is wrong…</p>
<p>Also, the binary star system. What is conserved. I foolishly put the potential energy of the system, but come to think of it, the star emit radiation so its not exactly a closed system</p>
<p>Any comments?</p>
<p>Huh… Wat was it then? I thought i read that same question in a practic test and it was interference</p>
<p>Oh and if the two surfaces were not parallel, wouldnt that affect things</p>
<p>So was the linear momentum conserved since momentum is always conserved?</p>
<p>sorry it was interference [was that E?]</p>
<p>What was the momentum of Box X</p>
<p>and what was the new projection of Particle A after the elastic collision</p>
<p>Energy cannot be destroyed an must be converted to some other form</p>
<p>the 1st and the 3rd graphs showed the same thing (acceleration)</p>
<p>for for the area under the graph</p>
<p>I just said only the 1st one showed something (displacement)</p>
<p>I said that the Resistance is 60 ohms for that 60W 120V question</p>
<p>What were the choices for what is conserved?</p>
<p>I put that the force they exerted on each other were the same</p>
<p>And yeah i think it was only displacemebt</p>
<p>i said that the tension was the same everywhere for the rotating thing question</p>
<p>And at pt A the velocity was the greatest for the planet</p>
