Many students experience anxiety before taking a test—particularly before taking a standardized test such as the AP® exam. As the teacher, you can help reduce that anxiety by familiarizing your students with the exam and having them practice basic, proven test-taking strategies.

1. Familiarize yourself and your students with the format of the exam. The chemistry exam is 3 hours and 15 minutes long and consists of the following sections:
   
1. Multiple choice (90 minutes)
1. 60 multiple-choice questions derived from the Curriculum Framework
2. Free-response questions (90 minutes)
1. Three long free-response questions
2. Four short free-response questions

The multiple-choice and free-response sections have equal weight, each accounting for 50% of the total exam score. Access more information about the exam at the AP® Chemistry Course and Exam Description.

2. The College Board® divided the new curriculum into 6 Big Ideas. Make sure you teach students the information covered in the Essential Knowledge points listed under each Big Idea. The Course and Exam Description delineates the topics the test includes (and those excluded as well).
   
   Assign your students practice questions like those asked on the exam. Carolina Investigations® for AP® Chemistry labs include Big Idea assessment questions that help students improve their writing strategies and prepare for free-response questions (FRQs) on test day. Consider administering these questions in a format that mimics the exam. To help students become comfortable answering questions under time constraints, structure the time for the practice test. Use Scantron® sheets to increase student familiarity with multiple-choice and grid-in questions.

3. To further strengthen your students' writing skills and better prepare them to answer FRQs, provide FRQs from past exams as practice. Require students to take 1 to 2 minutes to read each question and plan a response by drafting a quick outline or jotting down notes. The exam includes a 10-minute mandatory reading period before students can begin answering FRQs. Students are more likely to provide complete, organized responses if they organize their thoughts before answering the questions. Have students peer-review answers to practice FRQs so they can learn from each other's writing strengths and weaknesses. Provide students with examples of high-scoring answers and explain what sets apart a high-scoring answer.
   
   The Question = Claim + Evidence + Reasoning model of scientific argumentation is a powerful strategy students can use to answer FRQs. Using the model, students must read and understand a posed question. They directly begin answering the question with a claim statement, then back up their claim with specific examples of evidence, and finally, use reasoning to show how the evidence justifies the claim. There are many resources available online that provide additional information about this model of scientific argumentation.

4. Teach your students basic standardized test-taking strategies. Encourage those who have difficulty finishing a timed test to skip difficult questions, answer the questions they find easiest, and then return to the more difficult questions during any time remaining.
   
   Make sure students know they can write on the test booklets. Have them circle key words (such as "explain," "compare," and "which of the following do not"), draw figures where appropriate (for example, to help visualize food webs), and outline answers to FRQ essays, then write their answers.
   
   Help students tackle multiple-choice questions by having them try to answer each question—without looking at the given choices—before selecting the option that best matches their answer. If they don't know the answer to a multiple-choice question, they should eliminate the choices they know are wrong. The test gives a choice of 4 answers to multiple-choice questions; test takers who can eliminate 2 choices have a 50% chance of getting the correct answer. It is crucial to note that points aren't deducted for incorrect answers, so students should attempt to eliminate incorrect choices and answer as many questions as possible.
   
   Partial credit can be awarded for answers to FRQs. Encourage students to show their work in a clear and organized manner and provide as much information as they know; they may be awarded a few points even if they can't completely answer a question. For FRQs with multiple parts, have students attempt to answer each part of the question separately. If they do not know the answer to part (a), they should attempt to answer parts (b) and (c), as points are awarded independently to each part of the answer. Test-takers must answer FRQs in pen, so teach them to simply draw a line to cross out errors and continue writing. Answers to FRQs are not graded for spelling and grammar, but readers must be able to understand students' answers, so encourage neat writing as well as good spelling and grammar.
   

5. Inform your students about the exam location, date, and time. (Exam dates are available online.) Consider writing this information on your classroom board at least 1 month before the exam so students see it repeatedly before test day. Verify the testing site and be sure your students know that information at least 1 week in advance. If the site is off-campus, encourage students to drive by before test day to help facilitate a trouble-free arrival.
6. Be sure your students know what materials to take to the test and what will be provided. No calculators are permitted on the multiple-choice section of the exam. Any programmable or graphing calculator may be used only on the free-response section of the exam. They will be provided with equation tables. Students should take plenty of #2 pencils to answer the multiple-choice portion of the exam and plenty of black pens to answer the FRQs. Each student should also take a watch for tracking time and an ID acceptable for checking into the testing location. Since social security numbers are required on testing forms, they will need to know that information or have it in hand as well.

Final advice

Remind your students to relax, get a good night's sleep, eat a nutritious breakfast, and take a jacket in case the testing location is cold. Best of luck to you and your students!
