time, skip it and return to it after completing the rest of the section.
It’s important to practice this strategy because you don’t want to waste
time skipping around to find “easy” questions. Mark each question
that you don’t answer in your booklet so you can easily go back to it

On the calculator portion, keep in mind that using a calculator may
not always be an advantage. Some questions are designed to be solved
more efficiently with mental math strategies, so using a calculator
may take more time. When answering a question, always consider the
reasonableness of the answer—this is the best way to catch mistakes
that may have occurred in your calculations.
Remember, there is no penalty for guessing on the SAT. If you don’t
know the answer to a question, make your best guess for that question.
Don’t leave any questions blank on your answer sheet. When you’re
unsure of the correct answer, eliminating the answer choices you know
are wrong will give you a better chance of guessing the correct answer
from the remaining choices.
