Preparation Tips from Forums and Experts

Students on Reddit and prep sites often stress practicing under timed conditions to build stamina—many finish free-response early but struggle with pacing early on.

  • Time per question : Aim for ~2.3 minutes per multiple-choice; 15 minutes per free-response.
  • Breaks : A short 10-minute break occurs between sections, so total exam day commitment is about 3.5 hours.
  • Scoring note : No penalty for wrong answers; free-response graded 0-9 per question by teachers.

Recent discussions highlight Desmos graphing calculator rules: allowed in specific parts, so master it now for 2026. Practicing full 195-minute mocks mimics the real pressure, turning "how long is it?" worries into confidence.
