Prepare for the SAT early, devoting at least 30 minutes daily. A few high schools offer SAT preparation classes, which can be helpful if you aren't very self-motivated or want guidance for your studying. The Educational Testing Service (ETS), which publishes the SAT, offers an official study guide and an official SAT online course for a fee. ETS and websites, however, offer several free alternatives.
Read slightly challenging fiction and/or non-fiction. A large portion of the SAT tests reading and writing ability, which makes it important for you to read. Reading also helps to improve vocabulary, which the SAT tests.
Register for services ETS offers for free online. ETS will email you its question of the day, which rotates among SAT subjects. That will help you understand the kinds of questions on the SAT. Also use ETS' sample practice questions. Planning how many questions you will answer per day is helpful. After you practice for a while, complete the online practice test. It will give you a sense of the examination's structure and length and help you decide how you can tackle the SAT.
Find other free resources online, such as Number2.com, which offers a question of the day, word of the day and practice questions. Use a website that suits your learning style.
Follow a strategy for higher scores. Many websites and books spend a lot of time trying to sell "secret" tips for SAT success, but achieving higher SAT scores comes down to an ability to answer questions quickly and confidently. Skip questions for which you don't know the answer so you can get as many points as possible for answers you know. When you complete those questions, return to the difficult questions to see if you can at least eliminate one of the possible answers to increase your chances of selecting the correct answer. If you can't, then leave the question blank because you're deducted 1/4 point for every wrong answer while blank answers are null.
