Five Digital SAT Math Strategies That Save You Time
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.
