​​​​​​​​​​​​​PREPARE for the SAT or the ACT:

The SAT focuses more on reasoning than content.  It includes sections in Mathematics, Evidence-Based Reading, Writing & Language, and an optional Essay.

The ACT focuses more on content than reasoning.  The ACT includes sections in Mathematics, Science, Reading, English, and an Essay.

​Prime Numbers helps students prepare for the SAT or ACT.  Students meet weekly in small groups with highly qualified instructors for 8 sessions prior to their test. 

We offer classes in SAT Mathematics, SAT Reading & Writing, ACT Mathematics & Science, and ACT Reading & Writing.  You can choose to work on just one area, or take both sessions to prep for the entire test.

Our SAT and ACT Prep courses teach students about the test they'll be taking, including types of questions, test structure, and scoring.  We share test-taking strategies for navigating the exams and ensure students understand the instructions for different sections.  We review specific skills and concepts that students need to know and be able to do, and we explore a variety of problem-solving approaches.  And we administer a full-length proctored practice test to simulate testing conditions, with individual feedback on specific areas of focus.  Students work with us to get the practice they need to be prepared for their test.

Our SAT/ACT Prep Classes include the following:

  • 12 hours or 24 hours of instruction over 8 or 16 sessions
  • ​One full-length proctored practice exam
  • Individual score analysis and feedback
  • Plenty of practice problems and review
  • ​Test-taking strategies
  • Small class sizes
  • ​Official practice book to keep
