> The AP Chem score calculator combines your multiple-choice result with the points on the three long and four short free-response questions into a 0–100 composite and estimates your AP Chemistry score from 1 to 5.

## Inputs

- Section I – multiple-choice correct (0–60)
- Long question 1 (0–10)
- Long question 2 (0–10)
- Long question 3 (0–10)
- Short question 4 (0–4)
- Short question 5 (0–4)
- Short question 6 (0–4)
- Short question 7 (0–4)
- Composite needed for a 5 (estimate) — Estimate – the College Board sets the real cut-off after each exam; edit it if you have better data.
- Composite needed for a 4 (estimate)
- Composite needed for a 3 (estimate)
- Composite needed for a 2 (estimate)

## Results

- Composite score (0–100)
- Estimated AP score
- College Board qualification
- Composite points to the next AP score
- … equal to this many more multiple-choice questions
- Free-response points (of 46)
- Multiple-choice percentage
- Free-response percentage

## Formula

```
Composite = MCQ ÷ 60 × 50 + (L1 + L2 + L3 + S1 + … + S4) ÷ 46 × 50 · AP score from estimated cut-offs
```

## Explanation

AP Chemistry is split evenly between 60 multiple-choice questions (90 minutes, 50% of the score) and seven free-response questions (105 minutes, 50%). Three of the free-response questions are long, multipart problems worth 10 points each; the other four are short, multipart questions worth 4 points each, for 46 free-response points in total.

To combine sections with such different point totals, each is scaled to 50: a multiple-choice question is worth 0.83 composite points and a free-response point about 1.09. Small improvements on the long questions – showing the set-up of a calculation, stating units, justifying a claim with particle-level reasoning – therefore pay off quickly.

The College Board does not publish the composite cut-offs, and they move a little every year. The defaults here are **estimates** in line with the cut-offs on released AP Chemistry practice exams (a 5 from about 72 of 100); edit them if you have newer information. Section format and weights follow the College Board's current AP Chemistry exam description (exam year 2026–27).

### How to use the AP Chemistry Score Calculator

- **Section I – multiple-choice correct (0–60)**
- **Long question 1 (0–10)**
- **Long question 2 (0–10)**
- **Long question 3 (0–10)**
- **Short question 4 (0–4)**
- **Short question 5 (0–4)**
- **Short question 6 (0–4)**
- **Short question 7 (0–4)**
- **Composite needed for a 5 (estimate)** — Estimate – the College Board sets the real cut-off after each exam; edit it if you have better data.
- **Composite needed for a 4 (estimate)**
- **Composite needed for a 3 (estimate)**
- **Composite needed for a 2 (estimate)**

Results update as you type, every field has its own unit menu, and everything is calculated in your browser.

### How it works

Enter the multiple-choice questions you expect to answer correctly and your expected rubric points on each free-response question. Both sections are scaled to 50 points, added, and compared with the estimated cut-offs.

### Worked example

42 multiple-choice questions correct, long questions 7, 6 and 8, short questions 3, 2, 4 and 3 (33 of 46). Composite = 42 ÷ 60 × 50 + 33 ÷ 46 × 50 = 35.00 + 35.87 = **70.87**, an estimated **4**. Only 1.13 composite points – two more multiple-choice questions – separate it from the estimated 5 cut-off of 72.

### What each result means

- **Composite score (0–100)** = [Section I – multiple-choice correct (0–60)]÷60×50 + ([Long question 1 (0–10)] + [Long question 2 (0–10)] + [Long question 3 (0–10)] + [Short question 4 (0–4)] + [Short question 5 (0–4)] + [Short question 6 (0–4)] + [Short question 7 (0–4)])÷46×50
- **College Board qualification** = [Estimated AP score]
- **Free-response points (of 46)** = [Long question 1 (0–10)] + [Long question 2 (0–10)] + [Long question 3 (0–10)] + [Short question 4 (0–4)] + [Short question 5 (0–4)] + [Short question 6 (0–4)] + [Short question 7 (0–4)]
- **Multiple-choice percentage** = ([Section I – multiple-choice correct (0–60)]÷60)×100
- **Free-response percentage** = (([Long question 1 (0–10)] + [Long question 2 (0–10)] + [Long question 3 (0–10)] + [Short question 4 (0–4)] + [Short question 5 (0–4)] + [Short question 6 (0–4)] + [Short question 7 (0–4)])÷46)×100

## Worked example

Inputs — Section I – multiple-choice correct (0–60): 42; Long question 1 (0–10): 7; Long question 2 (0–10): 6; Long question 3 (0–10): 8; Short question 4 (0–4): 3; Short question 5 (0–4): 2; Short question 6 (0–4): 4; Short question 7 (0–4): 3; Composite needed for a 5 (estimate): 72; Composite needed for a 4 (estimate): 58; Composite needed for a 3 (estimate): 42; Composite needed for a 2 (estimate): 27.

Results — Composite score (0–100) = 70.87; **Estimated AP score = 4**; College Board qualification = Well qualified; Composite points to the next AP score = 1.13; … equal to this many more multiple-choice questions = 2; Free-response points (of 46) = 33; Multiple-choice percentage = 70 %; Free-response percentage = 71.74 %.

## Key terms

- **Long free-response question**: A multipart lab or data problem worth 10 points.
- **Short free-response question**: A multipart question worth 4 points.
- **Scaling**: Converting each section to the same 50-point weight before adding.

## FAQ

**How is AP Chemistry scored?**
60 multiple-choice questions (50%) and 7 free-response questions (50%): three 10-point long questions and four 4-point short questions.

**What composite do I need for a 5 in AP Chem?**
Roughly 72 of 100 on our estimate – for example 45 MCQ correct plus 32 of 46 free-response points.

**Is a calculator allowed?**
Yes, on both sections of the current exam, together with the periodic table and the equations sheet.

**Are AP Chem cut-offs low?**
Compared with other AP exams, yes: about 60–65% of the available points has historically been enough for a 4 or 5.

**Do partially correct free-response answers earn points?**
Yes – each part of a question is scored separately, so a correct set-up can earn points even with a wrong final number.

**Does this calculator give my official score?**
No. It gives an estimate; official scores are released in July.
