@Orcmeister For me as a person who took all the practice test I could I found that FRQ section always had one question of enthalpy (delta h calculation) and Gibbs. Also there is always one question on acid base, solubility equilibira (including precipitation reaction), and electro chem (most likely galvanic cell). Kinetics is also frequently asked including finding partial pressure and lab procedures. And sometime they will throw in some oddballs like Beer’s law and etc. If you think you got all of these you will get a solid 5 on your FRQ. But if you didn’t I recommend going for big 5 which is acid base, solubility equilibrium, electro chem, gibbs (including enthalpy and entrophy), and kinetics. I found that the MCQ’s cover almost most of the subjects so during the test just go for the process of elimination. And if you are doing the practice exams try not to search up on the internet or look at the answers since it will give you inconsistent results. And mimic the TEST SETTINGS! meaning remove all the things that will distract you from focusing on the test.
Good luck!
Hey guys, four days till the AP test!!! I’m doing okay on the practice tests, getting mostly 4’s, but I really want a 5. Anyone have any tips as to how to remember the different equations for acid bases(strong strong, weak strong, strong weak, weak weak). And do you guys have any easy ways to remember the process of a titration? Or in a redox problem(such as 2016 frq 4b) the one on the college board, how do I know which equations to flip, to change the sign for the cell potentials. Please answer quickly, the exam is in four days…
Also anyone have any inspiring stories of passing AP tests with little to no studying? If I hear those I might feel better lol
Hey Guys! Just popping in. At this point, I kind of know I’m going to fail this exam :)) But whatever, I got my B!
Okay, so on a serious note, I legit just got a 1 on the exam just now. I kind of want to at least try to go for a 2, I don’t know why. I was thinking about cramming with PR and hoping for the best! What do you guys think?
Your best bet to cram would be NMSI videos @ apchemistrynmsi.wikispaces.com
This lady’s lecture notes are a textbook and a half. Combined, all the videos total 48 hours. If you wanna cram, there ya go 
Is there a page with the make up of the test? Like what percent each big idea is gonna be? Also, does anyone know how to do electronegativity for calculating bond polarity when the test doesn’t give you the values? Thank you!
@DLithium You wont need to do electroneg unless they give you the charts
@kassh4 thank you!
Does anyone know how partial credit works on the free response? For example, do I get some points for the answer and some points for the units? Or would I miss the whole point entirely? Also, if I calculated a wrong value at, say B, and question C needed the value from B, would I get a point if my answer was wrong but the process of calculation was right?
anyone gonna reply to my earlier post?
I took the Biology regents seven times and graduated on time. Hope this helps @Awesome2020
Could someone provide a comprehensive list of every thing that needs to be memorized? Thanks!
Also, does anyone know like a 3-hour-or-so-long video that just gives a brief refresher/overview of everything?
@Awesome2020
Alright, I’m going to be straightforward. AP chemistry is not easy. Passing with a 3 is less than 50% efficiency so that’s a bit comforting. As for your question. I’m electrochemistry there are galvanic and electrolytic cells. Let’s focus on galvanic. If you had two half reactions, you flip the negative one to make it positive so when you add them together, the overall cell potential is positive and therefore spontaneous.
@DLithium
There is no breakdown of percentages. However, I have seen that Big Idea 2 and 6 seem to be the most prevalent. Then 5 & 3, and then 4 & 1. These of course are just blatant observations. It could change up at any moment. Expect the test to have a good spread of all topics and be prepared for everything.
Alright so on free response, the graders follow your work and we can all be grateful for this. Let’s say, (of course this is a very easy example):
A) What is the mass of potassium?
B) If the theoretical yield is 200g, then what is the percent yield?
So % yield is (actual/theoretical) • 100
Let’s say you accidentally get the mass of phosphorus in part A, if you use that value in part B, and still do the calculations correctly (right steps and processes). Then they will give you credit.
Missing an earlier part does not mean you don’t understand the chemistry of another part. Thankfully, College Board and AP graders abide by this idea.

The new AP Chemistry exam has deemphasized memorizations. Look up PDF teacher made study guides on google and maybe you’ll find what you’re looking for. As for 3 hours of video going over all of AP Chemistry, no.
The closest and best thing to that is AP Chemistry Essentials by Bozeman Science. 71 quick videos covering all conceptual and essential knowledge in the course (about 10 hours).
To all AP Chemistry students. The exam is only 2 days away. We have worked hard all year and May 1st, 8:00 AM test date is among us. Hard work does pay off. Even if you do not receive a high enough score for college credit, you still walk out of the class with Chemistry knowledge which will make Freshman Chemistry in college so much easier.
ONE MAJOR CRAM STUDY TIP the night before: sleep. Your brain, on lack of sleep, builds up toxins (among other things) that hinders reasoning, recall, and recognition; all of which are vitally important to being successful on the exam. Make sure you also eat a carb and protein heavy breakfast! A little sugar won’t hurt.
The exam is 90 mins MC (no calc) and 105 mins FRQ (with calc). The FRQ’s have 3 long and 4 short. Try to spend about 20 mins on each long one and 10 mins on each short one.
Charge/replace batteries in your calculator (make sure it is allowed by checking the CB calculator policy on their website). Bring pencils and pens. Most testing centers will also allow snacks during the break.
Most testing centers will want you there at 7:30 AM, test at 8:00 AM.
Good luck to all! Study hard!
If anyone else has any more questions, feel free to tag me.
So I just took a mc from pr and got 22 wrong. Is this even a passing grade???
Out of 60 questions, 38 right out and 22 wrong is okay, you would get a low 4 or a high 3.
Oh ok also is the pr tests similar to the ap
