Free vs Paid SAT Prep

Khan Academy is free. Princeton Review is $1500. Here's an honest breakdown of where each fits.

When free is enough

  • Baseline 1200+, target 1400. Khan Academy + 8 official tests give plenty of reps.
  • You self-direct well. If your friend gets a 1500 from free resources, you can too — IF you actually do the practice consistently.
  • Budget = $0. Free beats nothing every time.

When paid is worth it

  • You want a predicted score. Khan doesn't tell you “you'll get a 1340 ±40 if you take the test today.” StudentNest does.
  • Baseline below 1100. You need adaptive routing to your weakest skills — free tools assume you already know where to drill.
  • Target 1500+. The last 100 points need targeted mock-and-review — more iterations than 8 official tests give you.
  • You hate studying alone. Pay for accountability (an app that nudges you daily beats a $1500 tutor most of the time).
