  • Use the official SAT prep program (a College Board partnership) if you're preparing for the SAT โ€” it's free, uses real practice questions, and personalises your study plan.
  • Parents can create a parent account linked to their child's to monitor learning progress, time spent, and areas needing improvement from a dedicated dashboard.
