Take the test strategically and review only what you need to know.
This is the best way to improve your score.
Instead of trying to teach you everything there is to know about environmental science, we focus on test-taking strategies.
We will review some hard science as well.
Rather thancluttering your brain, we'll look at the environmental science you need to know for the test, explaining and highlighting key concepts along the way.
We will give you some simple, straightforward strategies for tackling multiple-choice questions and for writing free-response answers.
Let's take a closer look at the multiple-choice section.
The exam covers a wide range of topics.
Even with our extensive review, you will not know everything about environmental science.
A two-pass system is recommended.
Answering the easy questions first is what the two-pass system entails.
The questions should be saved for later.
If the question is a "now" or "later" question, read it first.
If you think this is a "now" question, answer it in the test booklet.
Come back to it if it is a later question.
Transfer the answers to your bubble sheet after you've finished all the "now" questions.
If you want to repeat the process, flip the page.
After you've finished all the "now" questions, move on to the "later" questions.
The correct answer does not jump out at you immediately, so these are the ones that require you to eliminate the answer choices.
As soon as you answer these questions, transfer your answers to your bubble sheet.
Because you're skipping problems, you need to keep an eye on the bubbles on your answer sheet.
Answering all the questions on a page will transfer your choices to the answer sheet.
If you want to enter them one by one, make sure you double check the number next to the ovals.
It makes sense to assume that you need to know your material backwards and forwards in order to get the right answer.
If you don't know the answer beforehand, you won't be able to answer the question correctly.
This is also true of fill-in-the- blank questions.
We're taught to think that the only way to get a question right is to know the answer.
That is not the case on Section I of the AP Environmental Science Exam.
The multiple-choice section of the exam uses this technique the most.
Let's look at an example.
If this were a blank-style question, you would be in a lot of trouble.
Let's take a look at what we have.
You can conclude that we're talking about elements when you see the elements in the question.
You can eliminate these components if you remember that they aren't normally components of water.
It's the same forbacteria, so lose.
You are left with (B) and (E).
If you know that neither of these elements is a significant component of the atmosphere, you can get rid of (E) and see that the best answer is (B), but even if you don't, you have a fifty-fifty chance of guessing the correct answer at this point.
Process of elimination is the best way to approach multiple choice questions.
Even if you don't know the answer right away, you will know that two or three of the answer choices are not correct.
It is more difficult to identify a wrong answer than a right answer.
You are scored only on the number of questions you get right, so we know guessing can't hurt you.
If you guess on five questions, chances are you'll get one right.
You have increased your score by one point.
Let's add POE to the equation.
If you can eliminate two answer choices from each question, your chances of getting them right increase and so does your overall score.
Another way to get points on the AP Environmental Science Exam is to use word associations with your POE skills.
Chapter 12 of the book is the Glossary and you need to memorize it.
You're going to be tested on them on the AP Environmental Science Exam if you group them by association.
Air pollution is an example.
There are several compounds associated with various types of air pollution.
Ozone, VOC, and nitrogen oxides are all related to air pollution.
There is a question about pollution.
Let's think about the associations we just talked about.
The question is about smog.
Air pollution is associated with answer choices (C, D, and E).
There is a fifty-fifty chance of guessing correctly.
By combining the associations we'll offer throughout this book with aggressive POE techniques, you'll be able to rack up points on problems that might have seemed difficult at first.
To simplify biology, you need to organize terms into a few easily remembered packages.
Using mnemonics is the best way to accomplish this.
A rhyme or phrase is a convenient device for remembering something.
Environmental science is all about names.
Some Pollution Lands On Nature Constantly is also known as the first letter of each component.
If they help you remember, mekongonics can be as goofy as you like.
The important thing is that you remember the information, not how you remember it.
The way in which the question is asked is one of the traps on the AP Environmental Science Exam.
There are a few different types of multiple-choice questions.
Section I contains about 10 percent of the multiple-choice questions.
You need to remember that you're looking for the wrong answer with this type of question.
POE is the best way to approach them.
The correct answer is often wrong in the context of the question.
You're left with the one that doesn't if you cross off the four that apply.
This is an example of a question.
If you don't remember, the question is about waste.
The correct answer is that (C) would result in more waste.
The best way to answer these types of questions is to spot all the right statements and cross them off.
The correct answer happens to be the wrong one.
The questions don't prompt you on how many might be correct, but they are designed to have you select all of the correct answers.
Carefully analyzing each answer is required in this case.
Be sure to consider each choice carefully, determine which ones are correct, and then look at the answer options to see which one corresponds with the selection of answers you have determined is correct.
This is an example of a question.
The answer is correct.
The rain on the windward side of the mountains is caused by warm, moist air rising and falling.
The leeward sides of the mountains are dryer.
The correct answer must have something to do with precipitation.
The first answer is correct but the second and third are not.
The answer bank is designed to answer several questions.
It's important to know that choices can be used multiple times or never in a problem set.
This is an example of a question.
There are questions about the following fishing methods.
The method produces the most benthic bycatch.
The least amount of bycatch is produced by this method.
The most common method of fishing is this.
The answer to 1 is (A), the answer to 2 is (C), and the answer to 3 is (A).
All of the choices are fishing methods.
Several answers were not used, but option A was used twice.
Some answer choices may be used once, multiple times, or never, and this question type is tricky, so don't assume that each potential answer choice will only be used once.
You just learned about the different types of multiple-choice questions, so let's practice them.
Chapter 13 has answers and explanations.
Sea level rise can cover the island due to climate change.
Some barrier islands have mangrove colonies and protective dunes.
Barrier islands can be damaged by storms.
People living in suburbia may notice a decline in the number of cats in their house at the same time they hear coyotes more often.
A country with 10 million people had a birth rate of 6.3% and a death rate of 1.3% in 2000.
The population of that country will be close to 40 million if the rates remain constant and there is no migration.
