The questions are here. These are DRAFT answers and may change as errors are pointed out to me, and other thoughts come to my mind. Overall, another crushingly easy exam. Things have changed a lot sincequestion 14 the first question here was asked on the exam, but the operational FRQs reflect what the AP exam has become in the brave new world. Ho hum. As we all know, one never needs to pick up a test tube in order to answer these questions, so all of their work is in vain. Want to test lab? Have a lab exam. No need to be so patronizing. There certainly are huge numbers of teachers that have no business delivering an AP course, but the number of kids who are misplaced largely for political reasonsfar outweigh those numbers. So, we partially agree on this, just not on where the balance is found. Your email address will not be published. Question 3: a Remember when inorganic chemistry, solubility rules and equation writing mattered? Question 4: b This question is asked in 8th grade classes across America. Question 5: a PES is such an uninteresting addition. Question 6: Is this really an AP problem? Question 7: Oh look, more lab! John Doe on December 18, at pm. Adrian on December 19, at am.

You can see all CollegeBoard AP updates here. Section II of the AP Chemistry exam is 90 minutes long and consists of seven questions: three long and four short free-response questions. Here are some points to review:. There are full pages of information before Section II begins. Almost 50 equations and a slightly smaller number of constants are displayed for you, not including all the information given on the two tables. Instead, understand that some of this information will be needed for several of the answers, but that the rest is there to act as a smoke screen. Therefore, they have to devise a system in which the chem-savvy people find the facts they need, while the less-fortunate students get lost in the swamp of additional information. The topics covered in the free-response questions are usually fairly common chemistry topics. Most questions have many parts. Expect to write at least one paragraph or provide a multi-step equation for each letter. For each subquestion on a free-response question, points are given for saying the right thing. The more points you score, the better off you are on that question. Going into the details about how points are scored would make your head spin, but in general, the AP Chemistry people have a rubric that acts as a blueprint for what a good answer should look like. Every subsection of a question has one to five key ideas attached to it. If you write about one of those ideas, you earn yourself a point. There are also other strange regulations, but it boils down to this: Writing smart things about each question will earn you points toward that question. You have about 7 minutes for each short free-response problem and 20 minutes for each long one. Use the time to be as precise as you can be for each subquestion. When you answer free-response questions in practice or homework, have a timer running for 7 minutes for the short questions and 20 minutes for the long ones. Finally, since you are given a calculator to use on Section II, expect to use it. You can also guess that Section II will require you to use some of the formulas at the beginning of the section in your calculations. But it is a very good guess, kind of like picking the most favored horse to win a race. Still, take heart. Remember, the goal is not perfection.

Advanced Placement AP. AP Chemistry is a challenging subject, and many students feel nervous about taking on the exam at the end of the school year. But if you have a sense of what to expect on the AP Chemistry test well in advance, you'll be able to prepare appropriately for it. In this guide, I'll lay out the structure and content of the AP Chemistry exam, give you examples of different types of questions you'll see on it, and tell you how to study effectively for it! Due to the COVID coronavirus pandemic, AP tests will now be held remotely, and information about how that will work is still evolving. Like other AP tests, the AP Chemistry exam has two sections: a multiple-choice section and a free-response section. On both sections, you will have access to a periodic table of the elements as well as a chart listing any formulas and constants you might need for your calculations. Be aware that some of these questions will exist as a part of question groups which consist of a few questions that ask about one set of datawhereas others will stand on their own. The entire AP Chemistry exam is three hours and 15 minutes long. This year, the test will be administered on Thursday, May 7,at 8 am. You'll probably have to wake up at least this early on the day of the AP Chem test. Also, this corded monstrosity is what people used to set alarms before smartphones. Horrifying, I know. No points are taken off for incorrect answers on either section i. To calculate your raw multiple-choice score, add up all of your correct answers. This means you can earn a maximum of 60 points on the multiple-choice section. While the free-response section is a little more complicated, you should be able to figure out how many points you've earned if you have scoring guidelines. Short-response questions are worth 4 points, and long-response questions are worth 10 points, meaning you can earn a maximum of 46 points on this section. Next, convert these raw scores into numbers out of 50 so that they each make up half your final raw score. Say you got 40 out of 60 multiple-choice questions correct. You would convert this score to the equivalent fraction of 33 out of Then, if you got 30 out of 46 points on the free-response section, you would convert that score to the equivalent fraction of 32 out of 50 points. Finally, add the two scores out of 50 together to get your final raw score out of You can use the conversion chart below to estimate how your raw score might translate to an AP score on a scale of In this case, your raw score of 65 would be right in the middle of the 4 range. We can't be absolutely sure that these raw score ranges will correlate exactly with these AP scores because the curve is slightly different every year. If you find you're close to the bottom of your goal score range in practice testing, don't get complacent! You should probably put in a little more studying so you can feel more secure.
