<p>Oh wow! That means the curve is lower than 75%! ... 66% to be exact! Good news lol :D but still aim high... that's the only way to do well</p>
<p>So in combination with the statistics provided by both prometheus and Physics08, we would need to get about 47 raw points on MC and about 60 points in FR to get a 5.</p>
<p>
</p>
<p>Well magnetism is 9% of the test, while optics is 10%, and atomic/nuclear is 10%. So about 29% of the test, which isn't too bad because all you need it about 66% of the test.</p>
<p>good to hear about this!</p>
<p>I'm more worried about the free response. Are the free response math questions tougher than the mc or the same level?</p>
<p>FRQ are longer, but since they are longer, and you get to use a calculator, they are actually easier.</p>
<p>Does anyone know how hard the real MC is compared to Barrons?</p>
<p>I think the open ended is harder, because they take partial credits. So basically, you need to write every equation that is related to the problem, hopefully will get the point. That's y it's that hard...</p>
<p>True. But then generally the more you write the more points you will get, and as long you write something, you will get some points.</p>
<p>Is it just me, or is the PR book for physics doesn't cover enough info? I looked at an old test and there were various things that the PR book didn't cover.</p>
<p>"Determine the maximum kinetic energy of photoelectrons ejected by photons of one energy or wavelength, when given the maximum kinetic energy of photoelectrons for a different photon energy or wavelength."</p>
<p>Is it just KE (max) = hf - (work function)</p>
<p>How do we account qualitatively for the increase of photon wavelength that is observed, and explain the significance of the Compton wavelength?</p>
<p>
<p>Is it just KE (max) = hf - (work function)
</p>
<p>Yeah. using that equation twice though, as i think the problem wants you to find the work function first, then find KE</p>
<p>I dont get anything about photoelectric >_<</p>
<p>So is the PR book the best for AP Physics? How does the diffuculty compare with the real test?</p>
<p>Hey everyone!</p>
<p>In my class we just finished diffraction (single and double slits), the thin film experiment, and an overview of photons. We still have modern physics left to cover, but other than that we're done.</p>
<p>What do you recommend for review at this point? I have the PR and 5 Steps to a 5. I think the PR might be TOO LONG to go through at this point! It seems like reading the 5 Steps to a 5 book is a lot more feasible. What are you all doing? I'm most interested to hear from those of you that are JUST starting to review (and haven't necessarily been reviewing for weeks or months). I'd appreciate any input. Thanks in advance, and good luck to you all on the exam!!</p>

5 Steps to a 5 book
[/quote]
</p>
<p>Which book is this?</p>
<p>McGraw-Hill's book: <a href="http://www.amazon.com/gp/product/0071437134/sr=8-1/qid=1145502459/ref=sr_1_1/102-8419853-0091333?%5Fencoding=UTF8%5B/url%5D">http://www.amazon.com/gp/product/0071437134/sr=8-1/qid=1145502459/ref=sr_1_1/102-8419853-0091333?%5Fencoding=UTF8</a> (I recommend you read the reviews on that Amazon page)!</p>
<p>I'm planning on reading 5 Steps to a 5, cover to cover between now and the exam. I'll also use the PR for practice questions.</p>
<p>Does anyone have any suggestions at all as far as review goes? Please let me know! Again, good luck to you all!</p>
<p>Do as many practice tests as possible~</p>
<p>On the other hand, I still can't find an all-encompassing list of labs... does anyone know what labs we need to cover? Or we can make a list here...</p>
<p>The labs we've done
Calorimetry
Freefall
Circuit
Diffraction
Refraction
Rotational Motion</p>
<p>I didn't know the exam would have specific questions on labs coz if thats the case, I'm screwed.. We haven't done any formal labs at all..</p>
<p>Two parallel conducting plates, separated by a distance d, are connected to a battery of emf e (wierd looking e). Which of the following is correct if the plate separation is doubled while the battery remains connected?
a)the capacitance is unchanged
b)the potential difference between the plates is doubled
c)the potential difference between the plates is halved.
d)the electric charge on the plates is doubled
e)the electric charge on the plates is halved</p>
<p>why?</p>
<p>AP Exam has labs?</p>
