AP Chemistry Exam 2020

Exam timing

On exam day, you'll click on the link in your e-ticket 30 minutes before the start time for your exam and fill in some information.

A timer will show how much time remains until the start of the exam.

Once the exam starts, the first exam question will automatically appear, and another timer will start counting down.

Your timer will show 30 minutes. You should take 25 minutes to read the question and work on your response, and 5 minutes to submit it. When the timer gets to 5 minutes, an alert will show. Stop working at that time and begin to submit your response. Once your response to Question 1 has been submitted, you can’t go back to it.

When your submission for Question 1 is complete, the second exam question will appear and the timer will show 20 minutes. You should take 15 minutes to read the question and work on your response and 5 minutes to submit it. Again, the timer will give you an alert when 5 minutes remain. Stop working at that time and begin to submit your response.

Questions

Question 1 (25 mins.)

% of exam weight (rounded)

60%

Question name

Long free-response question

Question description

Question 1 presents students with a chemical system and/or data and assesses students’ ability to

  • Explain chemical phenomena using models, theories, and representations at the particulate and macroscopic levels
  • Draw conclusions from experimental results, identify and explain experimental procedures that are aligned to a question, and analyze sources of error
  • Analyze a system with quantitative reasoning
  • Support claims with evidence and reasoning

Corresponding free-response question (FRQ) type in the course and exam description binder

Similar in structure to a long FRQ on a traditional AP Chemistry Exam, with minor modifications to enable students to choose to submit either typed or handwritten responses.

Question 2 (15 mins.)

What’s covered

Units eligible for 2020 exam: Units 1–7

Units not included in 2020 exam: Units 8–9


Please note: Even when concepts in some of the included units (1–7) overlap with units 8–9, questions on the 2020 exam will not require student knowledge of concepts in units 8 and 9. For example, pH sensitivity (Topic 7.13) and free energy considerations of solubility equilibrium (Topic 7.14) are connected to Unit 8 and Unit 9, respectively, but students will not be required to use concepts from units 8 and 9 in order to answer questions successfully.

Other course-specific info

  • As on a traditional AP Exam, students will require access to the Periodic Table of the Elements (.pdf/174 KB) and the AP Chemistry Equations and Physical Constants sheet (.pdf/850 KB), and should access and/or print it before the exam.
  • Questions on the 2020 AP Chemistry Exam are designed such that required calculations can be done with a pencil and paper, with no calculator (including one with graphical or statistical capabilities) required. However, use of a calculator is allowed and may be helpful. Simple (“four-function”) calculators are freely available as apps for computers and phones (i.e., most or all internet-connected devices), and can be installed beforehand for use on the exam.
