So true… T_T The barrons test depressed my morale so hard. >:l</p>

<p>@ Two posts above, it’s, as far as I know, impossible. You have to memorize those. It’s basically gambling if you don’t know it.</p>

<p>Using Barrons and taking its practice test, I’ve found that it puts a LOT (I mean it when I saw a LOT) of extraneous information that you don’t really need for the test. IMO it’s pretty cluttered and recommends you to remember lots of stuff that you don’t need to, so when using this book I guess (maybe it’s for me, I don’t know) that you have to keep a level head and not get bogged down by smaller things. (Like formal charges, bond angles, 3-D//complex structures ;_; ) Maybe i just didn’t do well BECAUSE I’M ONLY ON CHAPTER 5 (The covalent chapter is ridiculously long). (■■■ begins now, I guess. That’s 10 chapters of chemistry to learn in 6 days.)</p>

<p>The Chem exam, I have to say IS harder than the BC exam. </p>

<p>The class is the other way around, though…</p>

<p>So I just got a copy of the 2008 released exam today, but my teacher won’t give out the answer keys. Can someone get me a copy of the answer key? I can send you Chem audit, 2002, 1999, and much more.</p>

<p>Collegeboard has a lot of old exams online:
[AP:</a> Chemistry](<a href=“College Board - SAT, AP, College Search and Admission Tools”>AP Chemistry Exam – AP Students | College Board)</p>

<p>I’ve been doing a FRQ test from there every day since monday.</p>

<p>Yeah, I’ve been doing tons of FRQs… I just figured something out. The “2008 Released Exam” is the same as the Audit test, and the “2004 Released Exam” is actually the 2002 released exam…</p>

<p>^ I heard they decided not to release the 2004 exam because some high school in California didn’t turn in their exams…</p>

<p>I just read on a website that you CAN’T use the equation sheet provided on the multiple choice.
Tell me this isn’t so.</p>

<p>It’s most definately so. Periodic Table only.</p>

<p>What is the equation sheet? Is that the solubility trends thing?</p>

<p>And are there any released multiple choice tests? I have the Peterson’s book, which I’ve been using. But it would be nice to have an accurate idea of how fast to work, etc.</p>

<p>To put it frankly, I’m ****ed.</p>

<p>What? Only periodic table? ****.
Thanks for replying though.</p>

<p>don’t worry. MC is usually mostly conceptual and easy mathematical calculations. (I think)</p>

<p>Yeah, I took AP chem last year. Only periodic table can be used on MC. A formula sheet is provided for FRQs. MC is almost all conceptual, but it’s a good idea to know some of the equations, though. If you look at some of the released exams, they actually test you the equations conceptually (kind of). </p>

<p>What exactly is a volatile liquid? Would HCl be classified as one?
(Not exactly related to AP, but I need to find the answer to this, and I’m hoping some people here would know it. :))</p>

<p>Really…what is so hard about the Chem? The multiple choice is mostly conceptual (with small simple math) and the FRQ gives you all the formulas you will need to know. Sounds like a party.</p>

<p>A volatile tends to have high vapor pressure as it wants to evaporate. HCl is polar covalent and I don’t know if it is volatile or not. :frowning:
Thanks for the attempt at morale boost jerry but at this point I have just given up.</p>

<p>HCl is a gas at room temperature, so I just thought it could be volatile…</p>

<p>@manatee:</p>

<p>"Intermolecular forces on the other hand are terribly weak, and attract molecule to molecule, and include so-called hydrogen “bond"ing (which is not really a bond!), dipole-dipole forces, and London forces. The weak London forces are the only sort of attractions that nonpolar molecules can feel, so nonpolar molecules tend to escape easily from their comrades in a liquid, to fly around the room, and thus they tend to be the most volatile. Size also affects volatility since the larger the molecule, the more surface area it has to stick to another identical molecule by these electrostatic attractions, and the less volatile it will be.”</p>

<p>hii, umm i was wondering if someone knows the curve or score necessary for a 3.
i do not want a 4 or 5 because i want to retake the courses in college for college credits.
basically…i missed the exam return deadline and just want some elective credits for my 90$.
i read the previous posts but saw nothing about the curve for a 3.</p>

<p>

</p>

<p>This is obviously true. You can’t use a calculator.</p>

<p>

</p>

<p>45-55% overall I believe?</p>

<p>^ How many right out of 6 essays on FRQ, approximately for a 3?
I know you should get like 40/75 for a 3 at least on MC.</p>
