AP Chemistry grading scale - how does it work?

Hey everyone, I'm a bit confused about the AP Chemistry grading scale. Can someone explain how the scale works, and what scores are needed to achieve each possible AP score? Thanks!

Hello! The AP Chemistry grading scale, like other AP exams, follows a scoring system with results ranging between 1 and 5. Here's a general breakdown of how these scores are determined:

1. The AP Chemistry exam has two sections: Multiple-Choice and Free-Response.

- The Multiple-Choice section consists of 60 questions, which account for 50% of your overall score.

- The Free-Response section has 7 questions, including 3 long questions and 4 short questions, totaling the other 50% of the score.

2. Raw scores are calculated for both sections. For the Multiple-Choice section, your raw score is simply the number of questions you answer correctly. For the Free-Response section, each question is reviewed by expert scorers who assign a raw point value based on standardized guidelines.

3. The raw scores from both sections are combined to create your composite score, which is then converted to the 1-to-5 AP scale. This scale is the final score reported for your AP Chemistry exam.

As for the exact scores required to attain each AP score, it may vary slightly from year to year based on the difficulty of the exam and the performance of all test-takers. Generally, the range of composite scores and corresponding AP scores is as follows:

- AP Score 5: Typically, around 70-75% of the maximum composite score

- AP Score 4: Usually within 55-69% of the maximum composite score

- AP Score 3: Often around 40-54% of the maximum composite score

- AP Score 2: Roughly 25-39% of the maximum composite score

- AP Score 1: Below 25% of the maximum composite score

Keep in mind that these percentages may not be exact for every year, but they give you a general idea of the score distribution for the AP Chemistry exam. Good luck with your studies!
