Section I contains 60 multiple-choice questions that deal with an experiment, set of data, or general knowledge of biology.
For a breakdown of the average percentage of each topic, please refer to.
The list of Science Practice topics can be found on the questions.
An example of how that topic might be tested in multiple-choice form is provided on the following pages.
We just want you to see how these might look in context, and with figures, diagrams, and/or charts, so don't worry about the answers.
The first appearance of the new format on a full-length exam was delayed due to the impact of the coronaviruses.
If there have been any updates regarding the wording of the questions or their representation within the test, please refer to your free online student tools.
The DNA fragments are separated by their size and charge.
The agarose gel well is covered with a buffer.
The gel and buffered solution has an electrical current applied to it.
You have to explain biological concepts, processes, and written models.
You may be asked to apply prior knowledge to a specific situation.
These questions usually give a specific example, then ask you to explain something more general about it.
The most obvious feature of these questions is that they start with a few sentences of information.
Many of the questions start with "which of the following best describes/explains..." and ask you to identify something's function or explain the general science behind a situation.
Marfan syndrome affects tissues in the body.
People with Marfan syndrome are usually tall and thin and have high levels of flexibility in their joints.
You have to analyze depictions of biological concepts and processes.
These questions are similar to Concept Explanation questions in that you may be asked to apply prior knowledge to a specific context or situation, except they will include a model, diagram, flow chart, or other representation instead of a written description.
You may be asked to explain relationships between different topics or specific concepts.
The questions come with a graphic.
Many of the questions start with "which of the following best describes/explains..." You may be asked to identify a trend on a figure or explain something in the figure.
Two species of anteaters cohabit in a rainforest with a mosquito species that is a carrier for a disease.
Both species A and B are not immune to the disease.
The mosquito species is the primary food source for a specific species of bat that lives in the rainforest.
Evidence, biological principles and theories, and/or evidence are required to make and support claims.
You may be asked to provide reasoning to justify a claim, explain the relationship between experimental results and larger concepts, and predict the effects of a disruption in a biological system or model.
Evidence could include a biological concept or process, a visual representation, and/or data.
These questions usually give a specific example, then ask you to make a claim or predict something about it.
Argumentation questions reference a source of data or information.
Concept Explanation questions are more focused on memorizent biological facts than on justification and evidence.
Lactase is found in many mammals and breaks down Lactose, a sugar found in milk, into glucose through a reaction.
Scientists theorize that lactase's efficiency is affected by temperature.
In order to test the hypothesis, the scientists dissolved lactase tablets in 200 mL of water and mixed 1 mL of the resulting solution with 2 mL of milk at different temperatures.
The scientists used test strips to test for the presence of sugar.
The strips are yellow when there is noglucose and green when there isglucose.
The methods best suited for an experiment can be determined by questions and methods.
You may be asked to develop a testable question to prove or disprove an idea.
You may be asked to identify experimental design components, such as independent and dependent variables and controls.
You may be asked to propose the next steps for an experiment based on the methods used.
The use of experimental design vocabulary, such as question, independent variable, dependent variable, and control, is the most obvious feature of Questions & Methods questions.
Representing & Describing Data questions ask you to describe data from a table or graph, including identifying data points, describing trends and patterns, and describing relationships between variables.
You may be asked to analyze a variety of representations, such as line graphs, bar graphs, logarithmic data, dual axes, histograms, box-and-whisker plots, and pie charts.
The accompanying graph or data table is the most obvious feature of Representing & Describing Data questions.
To draw conclusions from data, you need to perform calculations, such as finding averages, rates, ratios, and percentages.
You may be asked to determine if the information is statistically significant or different based on confidence intervals or error bars.
Statistical Tests & Data Analysis questions focus more on the data than the scientific principles and theories behind it.
The numerical data and numbers in the answer choices are the most obvious feature of the questions.
If you left a question blank, your teacher would mark it wrong.
That's not the case when it comes to the AP Biology Exam.
The worst thing you can do is finish the test.
Let's talk about timing.
If you were curious, the answers to the questions modeled on these pages are: (B), (C), (B), (A), (C), (C).
The time constraint of 90 seconds per multiple-choice question, 25 minutes per long essay, and 10 minutes per short essay is one of the main reasons that taking the AP Biology Exam can be so difficult.
You would probably do well on the test if you had all day.
We can give you more time for each question, even though we can't give you all day.
By slowing down and answering fewer questions.
The best way to improve your score on the AP Biology Exam is to slow down and answer the questions well.
Rushing through questions will hurt your score.
You're more likely to make careless errors when you rush.
Blank answers are not counted against you.
A broad range of topics is covered in the AP Biology Exam.
You won't know everything about every topic in biology even with our extensive review.
The Three-Pass System will help you earn more points by doing the questions you know first and then saving the ones you don't know for last.
The easiest questions are the ones that will get you the most points.
If you know the answer, savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay savesay Other questions will be more complex.
Decide if the question is easy, medium, or hard as you read it.
Do all of your easy questions during the first pass.
If you find a problem that is hard to understand, skip it.
The questions that you find easy are worth the same amount of points as the ones that stump you, so you should focus on the ones in the former group.
The medium questions should be saved for the second pass.
The questions are either time- consuming or require you to analyze all the answer choices.
Save the question for the last pass if it makes no sense from the beginning.
You are less likely to fall into a trap or settle on a silly answer.
Since 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.
You need to know your material backwards and forwards on most tests.
You probably won't answer the question correctly if you don't know the answer.
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's not the case on Section I of the exam.
The question types that are considered more difficult are EXCEPT and NOT.
This is the most important technique in the multiple choice section of the exam.
Let's look at an example.
The buds on trees and shrubs persist above ground during the colder months.
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 the question is about plants by seeing "woody stems" and "buds" in the question.
You know the answer is not (A) or (C) because plants don't have lungs.
You have narrowed it down to (B) and (D).
The two look very similar.
One of them is a trap.
If you don't know what "lentil beans" are, you have to guess.
Even if you don't know what lentil beans are, you probably know that they have nothing to do with gas exchange in plants.
The correct answer is (B).
The best way to answer multiple-choice questions is the Process of Elimination.
Even if you don't know the answer right away, you will know that two or three of the answer choices are not correct.
Random guessing won't affect your score according to the testing board.
The AP Biology Exam has no guessing penalty.
Each correct answer will give you one point and you won't lose any points.
You won't lose points for wrong answers, but you should guess aggressively and get rid of the incorrect answer choices.
If you eliminate a couple of answer choices, you have a better chance of getting the question right.
It's in your best interest to guess if you can eliminate as many as two answer choices.
Another way to get points on the AP Biology Exam is to use word associations with your POE skills.
You need to memorize the words in the Key Terms lists.
Since the testing board is going to ask about them on the AP Biology Exam, make sure you group them by association.
Let's look at the example of meiosis.
You will soon see that there are several terms associated with meiosis.
Synapsis, crossing-over, and tetrads are words that are not associated with meiosis.
In this book, we'll explain what these words mean.
Take a look.
Scientists theorize that the Golgi apparatus creates a cell plate between plant daughter cells.
This may seem like a difficult problem.
Let's think about the associations we just talked about.
The question asks about something.
Events that we've associated with meiosis are all mentioned in A, B, and C. Without even thinking about it, you've found the correct answer: (D).
Don't worry about the science for now.
By combining the associations we'll offer throughout this book and your aggressive POE techniques, you'll be able to rack up points on problems that might have seemed difficult at first.
The organization of terms into a few easily remembered packages is one of the keys to simplified biology.
Using mnemonics is the best way to accomplish this.
The names of chemical structures, processes, theories, and so on are what biology is all about.
A mnemonic is a convenient way to remember something.
Taxonomy is an important issue in biology.
A descending system of similarity leads from the broadest level to the most specific level of Organisms.
The complete order includes domain, kingdom, class, order, family, and species.
King Philip of Germany wanted to go to America.
As long as they help you remember, mekongonics can be as goofy as you like.
We'll give you mnemonics for many of the complicated terms we'll be seeing in this book.
If you like them, you can use ours or invent your own.
The important thing is that you remember the information, not how you remember it.
There are some questions you might encounter.
You need to remember that you're looking for the wrong answer with this type of question.
