Multiple Choice Questions:
* No penalty for wrong answers: There's no penalty for incorrect answers on the SAT multiple-choice sections. This means that guessing is always better than leaving a question blank. Even a random guess has a 25% (or higher for questions with fewer answer choices) chance of being correct.
* Informed Guessing: If you can eliminate even one or two answer choices, your chances of guessing correctly increase significantly. Try to eliminate obviously wrong answers before guessing.
Grid-In Questions:
* No penalty for wrong answers, but also no partial credit: Grid-in questions require you to write in a numerical answer. There's no penalty for incorrect answers, so if you have *any* idea, a guess is worth a shot. However, there's no partial credit, so a partially correct answer is marked wrong.
Overall Strategy:
* Time Management: Don't spend too much time on any single question. If you're stuck, make an educated guess or skip it and come back later if time allows.
* Prioritize Easier Questions: Focus on the questions you know you can answer correctly first. This will build confidence and ensure you get points for the ones you're sure about.
* Review: If time permits at the end, review your answers and reconsider any questions you guessed on.
In short: For both multiple-choice and grid-in questions on the SAT, guessing is always better than leaving a question blank. However, try to make educated guesses based on your knowledge and by eliminating incorrect answer choices whenever possible.
