Plugging In and Answer Choice Strategies

Outsmart the Test

You don’t always have to solve every problem by hand!

Plugging In

  • Try substituting numbers for variables to make problems easier
  • Plug in answer choices to see which one fits

Elimination

  • Cross out obviously wrong answers to improve your odds
  • Look for patterns in choices (like ascending order or similar values)

Why Use These Strategies?

They save time and help you avoid careless mistakes.

ACT Tip

If you’re unsure, make an educated guess—never leave a question blank!

Examples

  • Substitute 2 for \( x \) in an equation to check which answer works

  • Eliminate options that don’t make sense, like negative answers for a length problem
