Score calculator
AP® Chemistry Score Calculator
Put in how many multiple choice questions you got right (or think you would) and your points on each free-response question. You'll see your weighted composite, an estimated 1 to 5 for the May 2027 exam, and what it would take to reach a 3, 4 or 5.
The 1 to 5 here is a rough estimate. College Board doesn't publish the cutoffs, and there's no released conversion chart for this exam in its current form, so treat the score as a ballpark and the composite as the solid number. How we estimate
Your estimate
- Weighted composite
- 58 / 100
- Rough AP score
- 4
You're close to a cutoff, so this could be a 3 to 4.
An estimate, not a prediction. College Board sets the real cutoffs each year and doesn't publish them. See how we estimate below.
What you'd need
Based on our estimated cutoffs. Aim a few points higher to be safe.
| For a | Multiple choice right, with your free response | Free-response points, with your multiple choice |
|---|---|---|
| 3 | 17 of 60 | About 24% of the points (12 of 46) |
| 4 | 33 of 60 | About 50% of the points (23 of 46) |
| 5 | 48 of 60 | About 76% of the points (35 of 46) |
How the Chemistry exam is scored
Your multiple choice score is the number you get right, with nothing taken off for wrong answers. Each free-response question is scored with a rubric, point by point. College Board weights each part and adds them into one composite score, then turns that into a 1 to 5. Multiple choice is 50% of the Chemistry composite, and free response is 50%.
| Part | Most you can earn | Share of your score | Each question or point adds |
|---|---|---|---|
| Multiple choice (60 questions) | 60 questions | 50% | 0.83 of 100 |
| Question 1: Long answer | 10 points | 10.9% | 1.1 of 100 |
| Question 2: Long answer | 10 points | 10.9% | 1.1 of 100 |
| Question 3: Long answer | 10 points | 10.9% | 1.1 of 100 |
| Question 4: Short answer | 4 points | 4.3% | 1.1 of 100 |
| Question 5: Short answer | 4 points | 4.3% | 1.1 of 100 |
| Question 6: Short answer | 4 points | 4.3% | 1.1 of 100 |
| Question 7: Short answer | 4 points | 4.3% | 1.1 of 100 |
College Board gives multiple choice 50% and the seven free-response questions 50%: three long ones out of 10 points and four short ones out of 4, 46 points in all. It doesn't list separate weights for the questions, so we count every free-response point the same.
One multiple choice question adds 0.83 to your composite out of 100. Every free-response point adds 1.1. So one free-response point is worth about 1.3 multiple choice questions.
How we estimate your score
First we add up your composite score out of 100. Each part of the exam gets the share of your score that College Board gives it for the 2027 exam, and within a part, each point counts the same unless College Board weights the questions differently.
Then we turn the composite into a 1 to 5. College Board sets the real cutoffs each year after the exams are scored, and it doesn't publish them. The only official cutoffs anyone can see are in conversion charts College Board printed with some older exams it released in full. Each chart shows where the cutoffs fell on that exam, in that year. We turn each chart's cutoffs into a share of its total and average them.
For Chemistry, College Board printed charts with its 2002 and 2008 released exams. Both are from before the 2014 redesign: 75 multiple choice questions with no calculator, and different free-response questions. College Board also reset the Chemistry score standards in 2023. So use these cutoffs as a rough guide.
Because of that, the 1 to 5 here is a rough estimate. Your weighted composite is the more solid number: it uses College Board's own weights for the 2027 exam.
| Chart | 5 | 4 | 3 | 2 |
|---|---|---|---|---|
| 2008 released exam | 67%100 of 150 | 54%81 of 150 | 41%62 of 150 | 33%49 of 150 |
| 2002 released exam | 69%110 of 160 | 56%90 of 160 | 42%67 of 160 | 31%49 of 160 |
| Our cutoff (the average) | 68 | 55 | 42 | 32 |
Within 6 points of a cutoff, the calculator shows a range instead of one score, because the real cutoff could fall on either side of you.
