AAF is the placement test for precalc, calculus, and STEM majors. A 263+ places you directly into precalculus at most schools — skipping a full semester of catch-up math.
Placement threshold
263+ places you into precalculus / STEM track. Accuplacer is scored 200–300 per subtest — your college publishes its own cutoffs.
Sign Error — classic pitfall when factoring quadratics or distributing
Order of Operations — especially with exponents and radicals
Concept Swap — using a linear technique on an exponential problem, or vice versa
Study tip
Trigonometry and logarithms are the lowest-weighted topics but highest-missed. If you're short on time, drill these last but don't skip them — they're worth 15% combined.
