²Passport to advanced Math
(Familiar with more-complex equations or functions, geometry, trigonometry, and the arithmetic of complex numbers)
It is including applications of volume, surface, area, and coordinate geometry, properties of lines, angles, triangles, other polygons and circles.
80% of the questions are multiple-choice (45 questions). NO penalty for selecting an incorrect answer. (While the pre-2016 SAT had a one-quarter-point penalty)
20% of which are gridded-response questions (written in fraction, decimal, or positive integer), about 13 questions.
