2021 AP Test Changes Due to COVID-19

Due to the ongoing COVID-19 coronavirus pandemic, AP tests will now be hosted over 3 various sessions between May and also June. Your test dates, and also whether or not your tests will certainly be online or on paper, will depend on your institution. To learn more about how every one of this is going to occupational and gain the latest indevelopment on test days, AP digital review, and what these transforms suggests for you, be sure to inspect out our 2021 AP COVID-19 FAQ write-up.

What"s the Format of the AP Environmental Science Exam?

The AP Environmental Science exam readjusted considerably in 2020, so it"s vital that you know whether your review products are up-to-date or not.

The new test is 2 hrs and 40 minutes long and also consists of 80 multiple-alternative questions and 3 free-response questions. (Previously, the test lasted 3 hrs and also had 100 multiple-choice concerns and four free-response inquiries.) In addition, you are permitted to usage a graphing calculator throughout the whole exam.

You deserve to learn more about these significant alters to the exam in the brand-new APES Course Description.

Here"s a quick overwatch of the new AP Enviro exam format:

AP Enviro SectionTime# of Questions% of Score
Section 1: Multiple Choice1 hr 30 mins8060%
Section 2: Free Response1 hr 10 mins340%
TOTAL2 hrs 40 mins83100%

As you deserve to see, the multiple-option area, which comes first, is worth 60% of your final AP score and also is composed of 80 questions in 90 minutes; this indicates you"ll have actually a small more than a minute per question. Tbelow are no penalties for wrong answers, so be sure to always put something down!

Each multiple-option question comes through four answer choices, labeled A-D. (Before, the APES exam had five answer selections for each question.) You"ll acquire both stand-alone concerns and concerns in sets. In total, you can intend 3 to 4 sets on quantitative data (charts, graphs, and so on.), 3 to 4 sets on qualitative data (maps, models, and so on.), and also five concerns on a passage or text.

The free-response area counts for 40% of your full AP score. You"ll should answer 3 free-response inquiries, each worth 10 raw points, or around 13.3% of your final score. Since you will get 70 minutes for this section, this implies you"ll have approximately 23 minutes per question.

The 3 free-response question kinds will certainly remajor continual from year to year:

Concern 1: Deauthorize an investigationConcern 2: Analyze an eco-friendly difficulty and propose a solutionInquiry 3: Analyze an environmental trouble and also propose a solution doing calculations

What Does the AP Environpsychological Science Exam Cover?

Before we obtain right into the nitty-gritty of APES review, it"ll help to generally go over what the exam covers to assist put every little thing in context. Environpsychological scientific research is a multi-disciplinary topic that looks at ideas from science, background, existing events, and more.

In this area, we"ll be taking a closer look at the significant themes and topics on the exam.

AP Environmental Science Big Ideas

The test will touch on many type of locations, yet tright here are four primary themes, or "Big Ideas," as the College Board calls them, it seeks to focus on. Every question you watch on the exam will relate earlier to at leastern among these ideas, so they"re valuable to store in mind as you navigate your AP review procedure.

Here is just how each Big Idea is described in the AP Enviro Course and Exam Description.

Big Idea 1: Energy Transfer

Energy conversions underlie all eco-friendly procedures. Energy cannot be created; it have to come from somewhere. As power flows with systems, at each action, more of it becomes unusable.

Big Idea 2: Interactions Between Planet Systems

The Planet is one interconnected system. Natural systems readjust over time and area. Biogeochemical devices vary in capacity to recuperate from disturbances.

Big Idea 3: Interactions Between Different Species and the Environment

Humans transform organic devices and also have had actually an affect on the atmosphere for millions of years. Technology and population development have actually allowed humans to increase both the rate and scale of their impact on the atmosphere.

Big Idea 4: Sustainability

Person survival counts on occurring methods that will attain sustainable devices. A suitable combicountry of conservation and also development is forced. The monitoring of sources is essential. Understanding the function of cultural, social, and also financial determinants is necessary to the breakthrough of remedies.


AP Environmental Science Units

AP Environpsychological Science also has nine units, which consist of the content in the course and also on the final exam. These major topics are more particular than the over themes, and also learning them will certainly help offer you a much better idea of what specifically will certainly be spanned on the exam.

Each unit has numerous smaller topics within it; I"ve included a couple of examples of these for each major unit below. For the full list of topics, refer to page 20 of the Course and also Exam Description.

AP Environpsychological Science UnitSample Topics% of Exam Questions
Unit 1: The Living World: EcosystemsBiomes, carbon cycle, trophic levels, food chains6-8%
Unit 2: The Living World: BiodiversityBiogeography, environmental tolerance, adaptations6-8%

Unit 7: Atmospheric PollutionAir pollution, smog, noise air pollution, acid rain7-10%
Unit 8: Aquatic and Terrestrial PollutionPerson results, waste reduction, sewer treatment7-10%
Unit 9: Global ChangeGreenresidence impact, climate change, invasive species15-20%

What Do Questions Look Like on the AP Enviro Exam?

As mentioned, there are two sections on the AP Environmental Science exam: Multiple Choice and Free Response. Official sample difficulties from both sections are shown listed below. Samples come from the 2019-20 AP Enviro Course and also Exam Description.

Multiple-Choice Sample Question


To answer this multiple-alternative question, you have to understand what the term "nonanthropogenic" means. Let"s think of it in terms of the original term "anthropogenic," which refers to things (regularly problems through pollution) concerned or caused by humale activity; therefore, "nonanthropogenic" is points that are not resulted in by human beings but fairly by natural procedures.

This leaves us with two feasible answer choices: A or B (C and also D are both huguy contributors to contamination in the setting, definition they are anthropogenic). Photosynthesis, or choice B, doesn"t make any type of feeling because in this process, plants transform carbon dioxide into oxygen, not the other way around.

With cellular respiration, or choice A, animals breathe in oxygen and also create carbon dioxide, so the correct answer should be A.

Other multiple-option APES inquiries may refer to a graph or message, need calculations, and/or be part of a set of associated concerns. Later in this guide, I"ll go over wbelow you deserve to find more multiple-choice exercise questions and exactly how to usage them in your AP Enviro prep.

Free-Response Sample Question


Every free-response question on AP Enviro is worth 10 raw points. Here, you must propose a solution to an environmental problem using mathematical calculations (remember, you"ll have actually accessibility to a graphing calculator).

You have the right to earn as much as 1 point for (a), 3 points for (b), and also 2 points each for (c), (d), and (e).
