Why this question type matters on the PreACT 9
The PreACT 9 Math section has 38 questions in 45 minutes — a bit over a minute each. A calculator is allowed (the online test includes an on-screen one), but every problem is solvable without it, and mental-math fluency is what keeps you on pace.
Geometry covers area, volume, perimeter, the Pythagorean theorem, angles, and circles. Memorize the formula sheet on /strategy/math_geometry_basics.
