Good Sat Notes to Put on Calculator

Preparing for the SAT requires more than just memorizing formulas. Effective note-taking on your calculator can significantly improve your performance. This guide provides essential tips and examples to help you make the most of your calculator during the test.

Why Notes Matter on Your SAT Calculator

Your calculator is more than just a computational tool—it's a workspace where you can organize your thoughts and calculations. Proper note-taking can help you:

Keep track of important values and formulas
Visualize complex problems
Save time by avoiding repeated calculations
Stay organized during timed sections

However, not all notes are equally useful. The best notes are concise, relevant, and easy to reference quickly during the test.

Essential Notes to Include

Here are the most important types of notes to include on your calculator:

1. Key Formulas

Write down the formulas you'll need most frequently. For example, on the Math section, you might include:

Quadratic Formula: x = [-b ± √(b² - 4ac)] / (2a)

Pythagorean Theorem: a² + b² = c²

Circle Area: A = πr²

2. Conversion Factors

Include common conversion factors for units you'll encounter:

1 inch = 2.54 cm

1 mile = 5280 feet

1 liter = 1000 milliliters

3. Special Values

Note down important mathematical constants:

π ≈ 3.14159

√2 ≈ 1.4142

e ≈ 2.71828

4. Problem-Solving Strategies

Include brief reminders of effective strategies:

✔ Work backward from the answer choices

✔ Plug in numbers for variables

✔ Draw diagrams when possible

Formula Reference

Here's a quick reference of common formulas you might need:

Algebra

Quadratic Formula: x = [-b ± √(b² - 4ac)] / (2a)

Slope-Intercept Form: y = mx + b

Distance Formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Geometry

Circle Area: A = πr²

Triangle Area: A = (base × height) / 2

Pythagorean Theorem: a² + b² = c²

Trigonometry

Pythagorean Identities: sin²θ + cos²θ = 1

Law of Sines: a/sin A = b/sin B = c/sin C

Law of Cosines: c² = a² + b² - 2ab cos C

FAQ

What if I don't have enough space on my calculator for notes?

Focus on the most essential formulas and values. You can always write additional notes on the test booklet if needed, but having key information on your calculator saves time.

Should I write out entire problem solutions on my calculator?

No, keep your notes concise. Write down only the formulas, values, and strategies you'll need most frequently. The calculator is for calculations, not full solutions.

What if I forget a formula during the test?

Don't panic. You can often derive the formula from memory or use the process of elimination with answer choices. Having key formulas on your calculator helps, but understanding concepts is more important.

Should I include personal notes or reminders on my calculator?

Yes, but keep them brief. Personal notes like "Check units!" or "Watch for extraneous solutions" can be helpful reminders during the test.
