* Khan Academy: This is a great free resource partnered with the College Board. They offer practice questions, videos explaining concepts, and personalized study plans. While not a downloadable study guide in the traditional sense, it's a comprehensive and valuable free option.
* College Board Website: The College Board website itself offers some free practice tests and sample questions, though not a full study guide download.
* Public Libraries: Many public libraries offer free access to SAT prep books and online resources. Check your local library's catalog.
* Websites Offering Free Practice Questions: Several websites offer free SAT practice questions, but be wary of the quality and accuracy. Stick to reputable sources like Khan Academy.
It's crucial to avoid websites offering pirated or illegally downloaded SAT materials. These are often low quality, potentially inaccurate, and could expose you to malware. While free resources exist, investing in an official SAT prep book or using the Khan Academy resource is generally recommended for the best results.
