<p>Precalculus as a junior is already a year ahead in math, so she is likely one of the better students in math (it is almost a given that such students will score >600 on the SAT math unless they take it before completing algebra and geometry in high school). Assuming she does well in precalculus this year and calculus next year, she should be fine as far as math goes for engineering, unless the high school’s math is really deficient*.</p>
<p>If test taking skills are possibly the problem, she may want to practice those (e.g. how to guess, do the easy problems within a section first and come back to them, etc.).</p>
<p>*If this is true, then SAT math and AP calculus scores likely are low overall at the school, and/or recent alumni are being placed in remedial math at their colleges.</p>
