Q & A
What is the importance of using the initials C E R when writing an essay in the AP Chemistry exam?
-The initials C E R stand for claim, evidence, and reasoning. Using this structure ensures that the essay is thorough, providing not only the answer but also the justification and the logical reasoning behind the claim.
How does Jeremy Krug suggest students approach the multiple-choice section of the AP Chemistry exam?
-Jeremy Krug recommends using the three-pass method. During the first pass, students should answer the questions they know. In the second pass, they should attempt questions they are unsure about and try to eliminate wrong answers. The third pass is for taking a guess at the questions they don't know. After all passes, any remaining time should be used to check work and reconsider unsure answers.
What is the significance of significant figures in the AP Chemistry exam?
-Significant figures are crucial because they indicate the precision of a measurement or calculation. Students must use the correct number of significant figures in their answers, aligning with the data presented in the question or providing a reasonable number based on the context.
Why is it recommended to use a calculator that the student is familiar with on the AP Chemistry exam?
-Using a familiar calculator ensures that the student can efficiently perform calculations without wasting time learning how to use a new device. It also prevents potential issues with unfamiliar functions or features that could disrupt the exam.
What should students do if they are unsure about the number of significant figures to use in their answer?
-If unsure, students should use three significant figures, as this usually falls within the tolerance accepted by the AP readers and covers a range from two to five significant figures.
What is the policy regarding carry-through errors in the AP Chemistry exam?
-There is no penalty for carry-through errors. If a student gets an answer wrong in part (a) but uses it in part (b), they will still receive full credit for part (b) as long as the rest of the calculation is correct.
Why is it important to include units in the answers for the free-response questions?
-Including the correct units is essential as it shows an understanding of the physical quantities involved and ensures that the answer is meaningful and measurable. Omitting units may result in no credit being awarded for the answer.
How should students approach reading the questions on the AP Chemistry exam?
-Students should read the questions carefully, including the headers and lead-in sentences, as they often provide valuable information necessary to solve the problem. It's important not to skip over any part of the question.
What is the advice given for students who are unsure about an early part of a question on the AP Chemistry exam?
-If a student is unsure about an early part of a question, they should not leave the entire problem blank. Instead, they can make an educated guess and move on, as there is still a chance to earn points on later parts of the question.
Why does Jeremy Krug say not to say 'good luck' to the students taking the AP Chemistry exam?
-Jeremy Krug believes that success on the AP Chemistry exam is not a matter of luck but a result of hard work and preparation throughout the year. He encourages students with the confidence that they have what it takes to do well.
What are some general tips that Jeremy Krug gives for the day of the AP Chemistry exam?
-Jeremy Krug suggests getting plenty of rest the night before, having a good breakfast, sharpening pencils, and wearing a simple digital watch. These tips aim to ensure that students are comfortable and prepared for the exam.

📝 AP Chemistry Exam Essay Tips
Jeremy Krug provides last-minute reminders and tips for the AP Chemistry exam. He emphasizes the importance of being thorough in essays, using the CER method (Claim, Evidence, Reasoning) to structure responses. For instance, when comparing ionic radii, one should state the answer, provide evidence like the number of valence electrons, and explain the reasoning behind the evidence, such as electron-electron repulsion.
🔢 Significant Figures and Calculator Use
Significant figures are crucial; one should use the correct number as per the question's requirement or provide a reasonable number by matching the precision of given numbers. Jeremy also advises using a familiar calculator on the exam day and confirms that programmable calculators do not need their memory cleared before the test.
🧮 Multiple-Choice Strategy and Units
For the multiple-choice section, Jeremy recommends a three-pass method: first, answer questions you know, secondly, attempt those you're unsure about by eliminating wrong answers, and lastly, guess on the remaining questions. He also stresses the importance of including correct units in free-response answers and carefully reading questions to fully understand what's asked.
🧐 Reading Carefully and Avoiding Errors
Jeremy highlights the necessity of reading the AP Chemistry questions carefully, as headers often contain important information. He also mentions that there's no penalty for carry-through errors, so students should not leave questions blank and should attempt all parts of a question for the best chance of scoring points.
