Understanding AP® Chemistry Scoring
The AP® Chemistry exam uses a composite scoring system that combines your performance on both the multiple choice and free response sections. This calculator provides an estimate based on typical scoring distributions.
AP Chemistry Exam Structure
Section I: Multiple Choice (50% of total score)
- 60 questions in 90 minutes
- No penalty for wrong answers
- Scientific calculator allowed
- Periodic table and formula sheet provided
Section II: Free Response (50% of total score)
- 7 questions in 105 minutes
- Questions 1-3: Long free response (10 points each)
- Questions 4-7: Short free response (4 points each)
- Scientific calculator allowed
- Periodic table and formula sheet provided
AP Score Meanings and College Credit
Score 5 – Extremely Well Qualified
Demonstrates excellent understanding of chemistry concepts. Most colleges award credit equivalent to a full year of introductory chemistry.
Score 4 – Well Qualified
Shows strong mastery of chemistry principles. Many colleges grant credit or advanced placement.
Score 3 – Qualified
Indicates satisfactory performance. Some colleges may award credit or allow students to skip introductory courses.
Score 2 – Possibly Qualified
Suggests partial understanding. Most colleges do not award credit for this score.
Score 1 – No Recommendation
Indicates insufficient preparation. Colleges typically do not award credit.

Study Strategies for Different Question Types
Multiple Choice Questions
Focus on eliminating obviously incorrect answers and using dimensional analysis. Practice with released exams to become familiar with question formats and common distractors.
Long Free Response Questions (1-3)
These typically involve multi-step calculations or explanations. Read the entire question first, plan your approach, and show all work clearly for maximum partial credit.
Short Free Response Questions (4-7)
These are more focused and require concise answers. Practice explaining concepts clearly and performing calculations accurately under time pressure.
Score Distribution and Statistics
Based on recent AP Chemistry exams, approximately:
- 11-14% of students earn a score of 5
- 16-18% of students earn a score of 4
- 25-28% of students earn a score of 3
- 25-30% of students earn a score of 2
