<p>One thing your daughter should realize: The "penalty" for guessing is a misnomer, and if she can eliminate even ONE wrong answer, SHE SHOULD GUESS. If she leaves 5 questions blank, she earns 0 points. If she randomly guesses on those 5 questions, she will (on average) get 1 right and the other 4 wrong and earn a net 0 points on them. If she eliminates ONE wrong answer, she'll come out ahead on average. If she can eliminate 2 or 3 of the 4 wrong answers, she'll do even better. Anyone who advises students to avoid guessing or to only guess when they have eliminate 2 answer choices is an idiot when it comes to the SAT.</p>
<p>When your daughter takes the SAT, she needs has to be in the right frame of mind. She has to be like Charlie's Angels or James Bond - in other words, she needs to work quickly while avoiding the traps. The SAT is NOT the time or place to emulate Maya Angelou, Marie Curie, or Albert Einstein.</p>
<p>Your daughter needs to realize is that the SAT is a different world from the academic world and requires a completely different way of thinking. Your daughter has all the verbal skills she needs for the SAT. If she's made it through trigonometry, she's had all the math she needs for the SAT.</p>
<p>Unlike class tests, the SAT questions are carefully tested through the infamous "experimental" section. The questions have to fit a statistical model. One important criterion is something called "biserial correlation", and savvy test-takers can take advantage of this. If a question has a high biserial correlation, that means that the high-scoring students get it right and low-scoring students get it wrong. An example of a question that would have a low biserial correlation is one that asks for the square root of 4. High-scoring students know what a square root is and get it right. Lower-scoring students don't know what a square root is and get it wrong. But the lowest-scoring students think that a square root is that number divided by 2 and thus get it right by accident. The results of the experimental section would show the biserial correlation, and the question would be thrown out and perhaps replaced by one asking for the square root of 9.</p>
<p>One thing for your daughter to remember is that wrong answers are NOT pulled out of thin air but rather chosen to look attractive. The test makers figure out what mistakes students are most likely to make and incorporate them into answer choices.</p>
<p>Your daughter also needs to take into account the difficulty of the question. Except for the reading passages, the questions in a given section are arranged in order of difficulty (such as easy-medium-difficult, easy-medium, or medium-difficult). This arrangement plus the need for high biserial correlation is what makes Joe Bloggs (hypothetical student who is perfect at being average) such an indispensable partner. On easy questions, your daughter should trust her hunches, because Joe Bloggs gets these questions right. On medium questions, she should question her hunches, because Joe Bloggs is sometimes right and sometimes wrong. (This doesn't mean she needs deep thinking - she just needs to beware of booby traps.) On difficult questions, she should eliminate ANY answer that seems to jump off the page, that seems to "go with" the words in the question, that repeats a number in the question, or that is the result of simple operations done to numbers in the question (so if 2 and 3 appear in the question, eliminate 5 and 6 in the answer choices). Because Joe Bloggs is ALWAYS wrong on difficult questions (if he were right, it would be easy or medium), she should always ELIMINATE the Joe Bloggs answer(s).</p>
<p>For the sentence completions, your daughter needs to fill in the blanks BEFORE looking at the answer choices so she can bypass the booby traps. She also needs to know SAT vocabulary. The tougher vocabulary words are NOT used in everyday language. How many times have you heard the word "calumniate"? Or "abashed"? Or "comely"?</p>
<p>For the reading incomprehension questions, your daughter must NOT try to understand everything in the reading passages. She just needs to get a few key points (like the main idea and the information in the sentences with "trigger words"), and she should answer the questions BEFORE looking at the answer choices so she can bypass the booby traps.</p>
<p>The math questions should be even easier to game. There's the create-a-ruler trick, the plugging in trick (plug in the answer choices into the problem), the approximation trick, and the plug-in-strange-numbers trick (for the Quantitative Comparisons).</p>
