<p>Practice with old real SATs under test conditions. But she should note which answers she was not confident on, or which took her a long time, and spend extra time reviewing the problem afterward (whether or not she got it correct). Also, the after-test review should include trying any that were left blank due to running out of time.</p>
<p>Some problems are more easily solved by plugging in the answers to the question rather than solving it the usual way. If a question takes too long to handle, skip it, and come back to it if there is time left for this section.</p>
<p>It has been found that girls guess less often than boys do. She should be aware that guessing has a positive expected value if she can eliminate just one answer as certainly incorrect, and the same expected value as leaving the question blank if the guess is purely random.</p>
