<li>electrochemistry, my teacher refused to teach it. i had to teach the entire topic to myself (since there's ALWAYS a question on it...) second would probably be thermo</li>
<li>i was really interested in chemistry (chemistry major) so i always found myself studying for it a little bit every day.</li>
</ol>
<ol>
<li>I thought the equation writing was the hrdest but it may have just been the complex ion</li>
<li>If you're in the class you shouldn't need all that much extra studying other than the bits and pieces each day</li>
</ol>
<p>oh, hardest topic on the test. i thought you said hardest topic to learn.</p>
<p>yeah i'd have to agree with the equation writing. i got the complex ion question because i luckily looked over the back of the PR book with that exact equation. without it i wouldn't have known how many ligands.</p>
<p>I honestly thought it was all easy. Except the first one was just weird. It was kind of a gas phase equilibrium, except it had weird parts to it.</p>
<p>I didn't study for the AP. I even stayed up until 3 am the night before because I was in a 4-hour phone conversation with a friend.</p>
<p>Though, I must say acid/base equilibrium is my Achilles' heel at AP Chemistry. I was so happy when I opened the free response and it wasn't that!</p>
<p>The hardest one for me was definitely equation writing. They come up with very weird reactions, and normally this part of the test is very easy for me. But they come up with ones where u have complex metal ions like Al or Cr in there with a saturated solution, so u get coordinate covalent bonds which deviate from the stereotypical bond chemical principles.</p>
<p>Studying wise, I actually sat down and practiced with all the FR questions from previous AP tests (ap central). this helps out a lot, you sit down, do a section, and then look up the answer to see how u did. This added with the PR review book pretty much guaranteed me a 5 :). I really recommend taking the time to do some practice FR questions. They are very useful for what is arguably one of the hardest ap tests.</p>
<p>This is also the best time to take the SAT II in chem, fyi. they dont go as deep into the chem principles as ap does, but no extra studying is needed and it was rlly easy, got an 800!</p>
<p>Hardest topic: Acid/base and buffer solution calculation.

Haha, same here. I had a celebration in my head when I read the gas equilibrium question last year. </p>
<p>Study method: I had an awesome teacher with killer chapter tests. My teacher prepared us well, and so I thought I knew everything well enough that I didn't do much studying for the AP test. However, I did spend about five hours studying for every single test in the class. I didn't cram for the AP exam: I studied some the weekend before, and didn't study the night before. </p>
<p>We had chemistry labs every week. And the write-ups were hell because you had to use the skills you learned in the current chapter to do well on the lab. So we weren't just memorizing stuff, we had to utilize them in real life applications. This helped A LOT.</p>

<p>(My 760 seems pretty lame compared to your 800 and OP's 790)</p>
