AP Biology Grading Scale

AP Biology includes Grades 1 to 5 in the Grading Scale. Grade 5 is considered the best. Grade 3 is for qualifying the exam.

Exam Pattern in AP Biology- The duration of AP Biology exam is 3 hours. It includes 2 sections.

Section A: AP Biology Multiple Choice Questions (AP Biology MCQs)

Multiple Choice Questions-

  • This section includes 50% of exam scores.
  • It includes a total of 60 questions in two parts.
  • Total score is 60 points. 1 point for each correct answer.
  • The duration of time is 1 hour and 30 minutes.
  • It includes some weightings (science practices) in MCQs.
1.       Concept Explanation 25-33%
2.       Visual Representation 16-24%
3.       Questions and Methods 8-14%
4.       Representing and Describing Data 8-14%
5.       Statistical Tests and Data Analysis 8-14%
6.       Argumentation 20-26%


Section B: AP Biology Free Response Questions (AP Biology FRQs)

Free Response Questions-

  • This section includes the 50% exam score.
  • The duration of time is 1 hour 45 minutes.
  • This section includes 6 free response questions (FRQs) in two parts.
  • 2 long-form free response questions, and
  • 4 short-form free response questions.
  • It includes some broader senses.

In simple words, the AP Chemistry Exam has two parts: one with multiple-choice questions, and the other with Free Response Questions or written answers. Both parts together make your final score.

1.       Interpreting and Evaluating Experimental Results 8-10 points
2.       Interpreting and Evaluating Experimental Results with Graphing 8-10 points
3.       Scientific Investigations 4 points
4.       Conceptual Analysis 4 points
5.       Analyze Model or Visual Representation 4 points
6.       Analyze Data 4 points
