Advanced Placement ExamsThe key difference between the AP Biology exam and its previous iterations is that some students will be taking a digital version of the exam this year rather than the paper version. Read more about the AP Biology exam below. EDT — Digital exam, in school or at home One key difference between the digital and paper versions of the AP Biology exam is that students taking the digital exam will not have the opportunity to scan and submit any handwritten work, so students will not be expected to diagram or graph anything as part of their answer to free response questions. Also, students will be allowed to use this formula and equations sheet whether they take the paper or digital version of the AP Biology exam.

The site also includes daily videos. Study actively. Resist the urge to study passively, such as simply rereading your notes or reviewing lecture slides. Instead, find ways you can study actively read: effectively. One way to do so is to attempt the multiple choice and short answer questions at the end of each chapter in your biology textbook. Use flash cards or Quizlet as needed.

Get matched with a top tutor who got a high score on the exam you're studying for! AP Biology Sample Questions Now that you have a basic content outline, here are some examples of the types of questions you'll see on the AP Biology test so that you can get an even better idea of what to expect. This is helpful if you can remember basic facts about the disease that you can use to contextualize the question. The main part of the question asks what will be affected when you replace a hydrophilic amino acid with a hydrophobic one on a hemoglobin protein.

Choice D can also be eliminated because the internal secondary structure of the protein is not altered by the existence of the hydrophobic group. This would only affect how the molecule interacts externally with other hemoglobin molecules, as in choice A the correct answer. Now, this AP Bio question is worth a total of points the AP Biology Exam Description doesn't specify exactly how much this particular sample question is worth. As you can see, there are four distinct parts: A, B, C, and D. Each part asks you to do something different and is worth a certain number of points: Part A is worth points.

To earn these points, you must describe and explain the specific biological process or concept at play here, that would be the amino acid substitution and its effect on the mosquitoes. Part B is worth points. You must identify experimental design procedures in this case, that would be the dependent variable and the positive control. Part C is worth points. To get these points, you must analyze specific data given to you. In this example, that would be the data in Figure 2 the second image in the problem and in Table 1. Part D is worth points. You have to make and justify your predictions to earn full points here; this means you must provide clear evidence for your claim. In this sample problem, for example, you would have to write about how susceptible you think the mosquitoes will be to the insecticides while also backing up your claim with evidence from Table 1 and other data.

Ugh, gross! This leaf is full of trichomes. It is worth a total of 4 points as are all short-answer questions. Like the long-form question above, each short-answer question consists of four parts: A, B, C, and D. You must answer all of these to get full points. Part A is worth 1 point. To get this first point, you'll need to describe the characteristics of the biological process, concept, or visual model in the problem. With this particular question, you must understand the process of fertilization and how chromosomes do not double.

Part B is worth 1 point. For this point, you'll have to explain the relationships between two biological concepts or processes in the problem. In the sample above, this means you must explain the genetic relationship between individual 16 and individuals 1 and 2. Part C is worth 1 point. To earn this point, you must represent biological relationships in a model.

For this problem, you would need to simply fill in the blanks in the template. Part D is worth 1 point. For the question above, you would have to understand the intricacies of inheritance patterns and what role chromosomes play in them. There must be jobs out there for which you just have to collect plant samples. Start building your experience now by never showering. There are no point deductions for incorrect or blank answers. Scoring is a bit more complicated on the free-response section, which is scored by actual graders rather than a computer. Each of the four short-answer questions is scored out of 4 points, and each long free-response question is scored from 8 to 10 points. This can change from year to year based on the performance of students. This is the most recent estimate I could find regarding the methodology behind it; however, note that this is for the old pre version of the AP Bio test and is therefore not relevant to the newest version.

Red An absorption spectrum indicates the relative amount of light absorbed across a range of wavelengths. The graphs above represents the absorption spectra of individual pigments isolated from two different organisms. One of the pigments is chloropyll a, commonly found in green plants. The other pigment is bacteriorhodopsin, commonly found in purple photosynthetic bacteria. The table above shows the approximate ranges of wavelengths of different colors in the visible light spectrum. Identify the pigment chloropyll a or bacteriorhodopsin used to generate the absorption spectrum in each of the graphs above. Expalin and justify your answer. In an experiment, identical organisms containing the pugment from Graph II as the predominant light-capturing pigment are separated into three groups.

The organisms in each group are illuminated with light of a single wavelength mm for first group, mm for the second group, and mm for the third group. The three light sources are of equal intensity, and organisms are illuminated for equal lengths of time. Predict the relative rate of photosynthesis in each of the three groups. Justify your predictions. Bacteriorhodopsin has been found in aquatic organisms whose ancestors existed before the ancestors of plants evolved in the same environment. Propose a possible evolutionary history of plants that could have resulted in a predominant photosynthetic system that uses only some of the colors of the visible light spectrum. Matter continuously cycles through an ecosystem. A simplified carbon cycle is depicted below.

Answer: 5. Learning Objective: The student is able to apply mathematical routines to determine Mendelian patterns of inheritance provided by data. The reflected red and blue light appears purple. The organisms in each group are illuminated with light of a single wavelength nm for first group, nm for the second group, and nm for the third group. NOTE:: A student who combines two groups e. Absorbing visible light at all wavelengths may provide too much energy to the organism. Absorbing lights with longer wavelengths may not sufficient energy for the organism. Appropriate reasoning to support the proposal: Natural selection favored organisms that rely on pigments that absorbs available wavelengths of light. Endosymbiosis: chloraplasts evolved from cyanobacteria with pigments that used only certain wavelengths.

This is without taking the curve into account, which is different every year, but it should give you a rough idea of where you stand. If you score low 1 or 2 , you might make it your goal to raise your score to 3. Just keep in mind that some schools don't accept 3s for college credit , so you might want to aim higher after you make it to this first milestone. Most colleges consider 4 to be the standard cutoff for AP credit, so you should try for at least a 4 if you're hoping to get a head start in college. Once you're consistently scoring in the 3 range on this exam, you can set 4 or 5 as your goal. Even if you're already at the 4 or 5 level on AP Biology, you probably still have some room to improve.
