A: Just as they say about voting, the best time to take the new SAT is early and often. This is the case especially inasmuch as these tests do not generally reflect what you learn in school. This means that, with the exception of Math—which does require rudimentary understanding of advanced algebra concepts—there’s really no time that’s too early to start prepping.

With that said, we usually encourage students to begin incorporating  SAT prep into their life routines the summer after sophomore year. The advantage of starting over the summer is that it’s not competing with the full-time jobs of high school and extracurricular activities. The advantage of starting after sophomore year is that students have generally had enough math to get them through 95-98 percent of the SAT and are by then in a great position to get ahead of the curve. Think of it this way: if you start early, you’ll be done with these tests by junior fall or winter. And while everyone else is still suffering the tortures of the damned, you’ll be able to spend your after school time on something else… like college prep!

The other advantage of starting early is that most colleges (our analysis suggests 65-70 percent) superscore the SAT, which means that having more opportunities to take these exams will likely redound to your credit.

A: A good score, like curved space time, is relative. It’s relative to your personal standards and relative to the standards of the schools to which you’re applying. (To a certain extent, we might say that good scores are also relative to the standards of your parents and peers, but, as independent thinkers ourselves, we discourage all of our students from having such narrowly defined conceptions of success.)

More concretely, we encourage our students to aim for outcomes that put them above the 25th percentile for the schools to which they are applying. If you’re dead set on Princeton or MIT, this means that a 1480 or a 1500 is a good score. If you’re looking at other schools, that 25th percentile might start at 1200 or 1220. For more information on percentile scores at specific schools, see College Super-Scoring, Test Optional Status & Admissions Data.

If you don’t know where you’re applying, a good rule of thumb is to aim for a percentile that is roughly commensurate with your GPA percentile at your local high school. If you get mostly As and are in the top 10% of your class, you’ll probably want to aspire for a 1380 or higher. If you’re in the middle of the class, you’d probably benefit from an SAT that’s 1200 or higher.

If you don’t know where you stand in relation to your local high school class, we’d suggest looking at Naviance/Scoir/Maya Learning scattergrams and perhaps doing some light reconnaissance during free periods and downtime. Without being creepy about it, it’s usually not terribly difficult to get a ballpark sense based on conversations with friends and classmates.
