The **Digital SAT** has changed the game. With the Desmos calculator embedded in the entire Math section, students who know how to use it well have a real advantage.

Here are five strategies worth practising before test day.

## 1. Plug in Values (The "PITA" Method)

When you see variables in the answer choices, pick a simple number (like 2, 3, or 5) and plug it into the question. Then plug the same number into the answer choices.

> **Tip:** Avoid 0 and 1, as they often have special properties that can make multiple answers look correct.

## 2. Master the Desmos Calculator

You don't just use Desmos for graphing lines. You can use it for:
- Systems of equations (find the intersection)
- Regression (finding the line of best fit)
- Function evaluation

## 3. Work Backwards

For "Find the value of x" questions, start with the middle answer choice (usually B or C). If it's too small, go higher. If too big, go lower. This cuts your work in half.

## 4. Memorize the Few Things You Can't Graph

Bluebook gives you a reference sheet (area, volume, special right triangles), but some things are not on it and you still need to know:
- The circle equation: (x − h)² + (y − k)² = r², and how to complete the square to get there
- Exponent rules
- Percent change and ratio set-ups

## 5. Pacing is Key

Don't get stuck on one hard problem. In the adaptive testing model, getting the easy and medium questions right is crucial for your baseline score. Use **Mark for Review** on the hard ones and come back.
