How the SAT Is Structured
​Source: How the SAT Is Structured – SAT Suite | College Board
The SAT takes three hours and consists of three tests: (1) the Reading Test, (2) the Writing and Language Test, and (3) the Math Test. Compared to the ACT®, the SAT provides 43% more time per question:

• Most of the questions are multiple choice, though some of the math questions ask you to write in the answer rather than select it.
• On all questions, there’s no penalty for guessing: if you're not sure of the answer, it's better to guess than leave the response blank.

SAT Vocabulary

• You don’t need to learn a lot of unusual or difficult vocabulary words to succeed on the SAT. Instead, the words you’ll be asked about are words that come up often in college-level reading and professional life.  
• The SAT also doesn’t ask you to supply the definition of a word without any context to guide you. All of the words you’ll be asked about will appear in the context of reading passages, so you can use context clues to guide you to the best answer.  
• That said, it’s worthwhile to take the time to build your vocabulary by learning the meaning and usage of the words that appear most often in college-level assignments. If you do, you’ll have a much easier time with the test because you won’t have to spend time guessing from context clues what a word might mean. Your sight recognition of vocabulary words will help you read passages faster and with greater confidence.  
• You should also practice identifying the meaning of words in context with Official SAT Practice on Khan Academy®.

​Prefer to take a pencil and paper practice test? Your school might have paper practice tests, or you can download and print the paper practice tests (available here). 
You'll need a printer, pencil, calculator, and timer to take the tests. Here are some tips:   

• Mark your answers in the correct row of ovals on the answer sheet. Be especially careful if you skip questions. 
• It's okay to guess. You won't lose any points if you're wrong. 
• If you're using a screen reader or other assistive technology, we recommend the Microsoft Word practice tests optimized for you. If you prefer, you can also practice using the MP3 audio format. 

When you're ready to score your test, use the scoring guide and answer explanations provided with each practice test below to check your answers. We've removed SAT practice tests 2 and 4 and added practice tests 9 and 10.
