Like other AP tests, AP Biology has two parts: a multiple-choice section and a free-response section, each of which is worth 50% of your overall score.
These sections are then divided further into different types of questions. It consists of 60 multiple-choice questions and is one hour and 30 minutes long. (From 2013 to 2019, this section of the AP Bio test had 63 multiple-choice questions and six grid-in questions.) Although you have a minute for each question, I would recommend keeping your pace at under a minute per question on your first pass through the section.
The AP Biology exam is a long testthree hours long to be exact.
Starting in 2020, the Bio test will be undergoing some key structural changes in terms of questions and format, so it's important that you know what to expect and exactly how the test is structured.
This way you'll have some extra time at the end to go back and answer any tricky questions you skipped or guessed on.
There's no guessing penalty on the test, so you should answer every question, even if you have no idea which choice is correct (after you've tried to figure it out of course! The free-response section, which also lasts an hour and 30 minutes, is made up of six questions: four short-answer questions and two long questions.
Both of these focus on "interpreting and evaluating experimental results," with one requiring graphing (per the College Board description).
Here's an example of a long question: This question is heavy on analysis and isn't just testing your straight-up biology knowledge.
This is why a deeper understanding of the main topics in AP Biology is so critical: the difference between knowing the facts about something and comprehending how it works can be surprisingly large.
In addition to the four short-answer questions you'll get on the second part of the AP Bio exam, you'll get two long questions.
