AP Environmental Science: 3 Essential Study Strategies

Flipping passively through your notes isn’t enough to get a high score on the AP Environmental Science exam. Follow these three study tips to help you get the most out of your review.

Tip 1: Think About How Topics Are Related

Knowing each topic in isolation won’t help you much on the AP Environmental Science exam. Even if you know every single fact about the water cycle, if you can’t explain how it relates to other earth processes, how it affects (and is affected by) humans, how it has been impacted by climate change, and other connections, then you’ll miss a majority of questions on the exam.

AP Environmental Science is a very interdisciplinary class, and one of the major themes of the class is that the earth is an interconnected system.

Many questions will ask you to make connections among multiple topics

, so practice doing this whenever you’re reviewing your notes.

If you’re studying the atmosphere, for example, think about how the atmosphere affects animal and plant life on earth, how it affects other earth cycles, how it affects human populations, what the causes and effects of air pollution are, how the atmosphere is influencing and being influenced by climate change, and the changes humans can make to increase sustainability.

Tip 2: Get Used to Your Calculator

With big

changes to the exam starting in 2020

, you’ll now have

access to a graphing calculator

at any point on the AP Enviro exam; therefore, it’s extremely important that you get comfortable with using a calculator to solve AP Environmental Science questions both quickly and accurately.

Make sure you’re familiar with all the calculator functions you’ll be expected to know for the exam, as well as all the math formulas you’ll need to memorize.

It’s especially critical that you

practice using your calculator on the third free-response question

, which awards credit for showing your work and coming up with the correct answer to a quantitatively driven environmental issue.

Additionally, try to get in the habit of

checking and double-checking

your work on the exam with your calculator.

Tip 3: Know Major Environmental Events

AP Environmental Science isn’t strictly a science class; it also includes recent and current events as well as some law, among other topics. Unlike the other AP science courses, you can’t just know the scientific aspects of environmental science;

you also need to know about major environmental events


Studying the notes on major environmental laws above will help. You should also

use your notes from class to review other environmental events

. It can be very helpful as well for you to keep up on the news and know what the current major environmental issues are.


Conclusion: The Best AP Environmental Science Notes
