5 Common SAT Math Mistakes (And How to Avoid Them)

After tutoring SAT Math for over a decade, I’ve noticed that students often make the same mistakes repeatedly. The good news? Once you’re aware of these common pitfalls, you can easily avoid them and boost your score.

Mistake #1: Not Reading the Question Carefully

The Problem: Students often solve for x when the question asks for 2x or x + 5.

The Solution:

  • Always circle or underline what the question is asking for
  • Before moving to the next question, double-check your answer against what was requested
  • Practice this habit until it becomes automatic

Example: If a question asks “What is the value of 3x + 2?” and you find x = 4, your answer should be 3(4) + 2 = 14, not 4.

Mistake #2: Careless Arithmetic Errors

The Problem: Simple calculation mistakes that could have been easily avoided.

The Solution:

  • Slow down on basic arithmetic
  • Write out your work clearly
  • Double-check calculations, especially when dealing with negative numbers
  • Use the calculator strategically (not for simple operations)

Mistake #3: Misinterpreting Graphs and Charts

The Problem: Students misread axes labels, scales, or data points.

The Solution:

  • Always check axis labels and units
  • Pay attention to the scale (is it going by 1s, 2s, 10s?)
  • For word problems with graphs, match the context to the visual representation

Mistake #4: Forgetting About Negative Solutions

The Problem: When solving quadratic equations, students often only consider positive solutions.

The Solution:

  • Always solve completely for quadratic equations
  • Check if both solutions make sense in the context
  • Remember that distance and time problems usually only accept positive answers

Example: If x² = 25, then x = ±5. Depending on the context, both solutions might be valid.

Mistake #5: Poor Time Management

The Problem: Spending too much time on difficult questions and running out of time for easier ones.

The Solution:

  • Aim for 1.5 minutes per question on average
  • If you’re stuck after 2 minutes, mark it and move on
  • Always complete the easier questions first
  • Save 2-3 minutes at the end to check your work

The Power of Practice Tests

The best way to identify and eliminate these mistakes is through regular practice tests under timed conditions. I recommend:

  1. Taking a full practice test every 2 weeks
  2. Reviewing every mistake thoroughly
  3. Keeping a “mistake log” to track patterns
  4. Practicing similar problems until the concept is mastered

Your Path to SAT Math Success

Remember, SAT Math success isn’t just about knowing the concepts—it’s about executing them correctly under time pressure. By avoiding these common mistakes and building good test-taking habits, you’ll be well on your way to achieving your target score.
