<p>It is my understanding that formulas will not be provided at all for the multiple choice section of the exam. Which formulas are the more important ones that we should have memorized? Do we need to memorize the values of the constants as well?</p>
<p>wait, WHAT? We aren't given the reference tables for the MC?</p>
<p>OK I'm really starting to stress: Can someone who took the exam tell me: How quantitative are the multiple choice questions?? Because I hear we can't use calculators? Also, what things are not covered? Cuz do we need to memorize things like Planks constant or whatever to be able to do multiple choice questions or will we be able to use those "references pages" they provide--or is that just for the free responsE? AHH help!!!</p>
<p>collegekid88: We don't get anything for MC. You're right. Idk. I'm doing last minute studying (read: first time I'm learning most of this stuff. Ha...), and I'm compiling a formula sheet for myself. If you'd like, I can e-mail it to you in .doc when I'm finished.</p>
<p>trync2: Planck's is 6.62 x 10^-34 J * s Idk. That's probably the one thing that isn't hard to memorize.</p>
<p>no it doesn't</p>
<p>bump......</p>
<p>...as far as planks constant goes...</p>
<p>but what i'm asking is: People who already took it, whats not covered in multiple choice, because how can calculations be made with numbers like planks without calculator? and again, will we be able to use the formulas on the MC section or just the FR?</p>
<p>from what i'm hearing, the mc section stresses conceptual understanding more and occassionally, there will be a math problem but 99% of the time it has easy numbers to work with. you only have a periodic table which collegeboard gives you and no calculators, no forumla sheets. oh and gibs free energy(mostly just signs and not numerical) is an important equation. deltaG = -delta H - T*delta S.</p>
<p>You got Gibbs free energy equation wrong.</p>
<p>Delta H should not be negative, :-P. Just, had to point that out. lol</p>
<p>whoops my strange head just thought it was negative for some reason. thank you for correcting me :)</p>
<p>Thanks for the replies.</p>
<p>so its important to know that change in G = change in H minus T time change in S? what about change in G = -RTlnK? it could be on there too?</p>
<p>what about the really odd ones like clayperton equation?</p>
<p>i know most of them but hopefully the questions are kept at easy math, easy formula, and plain old idea level.</p>
<p>I got a 5 on AP Chem last yea, G=-RTlnK will probly not appear on MC, ln is too hard w/o calc.</p>
<p>I have never even heard of clayperton equation</p>
<p>THe types of math problems you get mainly involve factor labels (so like how many moles of this is such and such grams), gas laws with small integers, solution making problems (like, you have stock 15M solution, you want 100mL of 2M, how do you make it?) very easy numbers. If any of you took the chem SAT II, think about that math, you had no calc there.</p>
<p>I think you're referring to the Clausius-Clapeyron equation, which is such an insignificant equation in the context of the exam.</p>
<p>To give you a sampler, here's the 99 exam:

<p>Wow, the rare 1999 MC surfaces.</p>
<p>wait what did u do to get a 5 on your AP chem test?? I am aiming for a 4 because my grade DEPENDS on this AP exam. I am just not sure exactly what to study. any hints…PLEASE!!!</p>
<p>Dude, this thread is over five years old.</p>
<p>From what I’ve heard the 5 is from a 56% - 68%.</p>
