Restating the question, over-explaining your answer and excessively long sentences are some common mistakes that are too easy to make, especially in the long response questions. To prevent this, pay attention to the structure of your answers and make an active effort to be as efficient as possible.
The mean score on the exam for 2022 was 3.11 higher than the average of all AP subjects 2.92. The mean score for AP Biology is consistently higher than the mean score for all subjects. but still AP Biology is among the most difficult AP Courses.
What is biology? Biology is a branch of science that deals with living organisms and their vital processes. Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology.
Focus on hitting the key points, rather than writing everything you know about the topic. A-Level Biology tends to be quite a time-pressured exam, and running out of time is just throwing away marks – you always get 0 for a question you don't answer!
“The difficulty in biology lies in its complexity,” says Draft. “You have to develop an intuition for the principles that underlie this seemingly endless, chaotic diversity of protein cells in life. There's a lot of knowledge to learn, a lot of jargon, and a lot of specialized techniques.
Flash cards are a really good way to help with memorization. Biology is full of illustrations and they can be really helpful when learning how all the different components of a cell work together. Redrawing, tracing, labeling, or printing out diagrams are all helpful when figuring out the application of each term.
LEARN Your Mark Scheme. Biology is a hard A-Level subject despite its soaring popularity. Do you know that only 12.8% achieved an A*, and just 21% received an A? Let's compare that to the most popular A-Level subject of 2022: Maths.
