This SAT ELITE bonus section provides dozens of tips and extra-hard challenge questions exclusively for those students who are working toward a perfect 1600 SAT score. It is designed to be used in conjunction with the SAT ELITE text. Here’s how to make the most out of this bonus section:
Step 1: Read the 25 Study Tips in this section and start your personal notebook or journal for SAT prep. Start your full-scale SAT prep at least 12 weeks prior to your first official SAT.
Step 2: Take the Diagnostic SAT in Chapter 2 strictly timed and in one sitting.
Step 3: Score the Diagnostic SAT and use the detailed answer key to pinpoint areas for review. Note which kinds of questions gave you trouble, and find the chapters and lessons in SAT ELITE that correspond to those skills. Record your results and study plan in your notebook or journal.
Step 4: Set aside 30 minutes per night to work through your study plan that includes (1) reading and annotating the lessons and completing the exercises in SAT ELITE you found in Step 3, (2) completing 2-3 challenge questions each day from this section and reviewing the detailed answer explanations, particularly the references to the relevant lessons in SAT ELITE, and (3) reviewing the 25 study tips as necessary to make sure you are staying on track. Keep track of your daily progress in your notebook or journal.
Step 5: Each week, complete one practice SAT from Chapter 10 of SAT ELITE or from the College Board website, strictly timed and in one sitting. The practice tests in SAT ELITE are “heavyweight” tests designed to be slightly more challenging than the real thing, but it’s also important to take “official” College Board practice tests every once in a while to get a realistic gauge of your progress and a solid sense of the SAT as it is officially administered. Record your results and thoughts in your notebook or journal. Whenever you encounter real problem spots or frustrations, talk to a friend, teacher, or tutor about how to break through them.
Step 6: Review the results of each practice SAT and revise your study plan accordingly as you approach your score goal. Write yourself encouraging notes when necessary, and stay faithful to your plan!
Consistency and confidence are the keys to success. It’s better to make a little progress each day than to cram once or twice a week. It’s also essential to use your setbacks wisely. Look at your mistakes as opportunities to improve and learn! Good luck!

[1] Online conversations are unproductive and even toxic because they are poorly structured and incentivized. [2] They encourage us to accumulate “likes,” “shares,” “upvotes,” and “retweets” rather than build supportive relationships, solve problems, make sound arguments, influence leaders, or discover truths. [3] We send our thoughts into echo chambers, where like-minded people give us thumbs-up, instead of listening to opposing viewpoints that might expose potential flaws in our thinking or open us to new insights. [4] Within these comfort zones, we have no reason to understand or persuade people who don’t already share our views. [5] They promote “engagement” rather than empowered and critical thought.
