A complete two-module digital SAT Math practice test built from a Polynomials / Factor & Remainder Theorem / Exponential Models problem set — every item rewritten into a harder, original variant, all multiple choice, scored on the real 200–800 scale.
Polynomial multiplication & coefficients, factor/remainder theorem, root sums, graph–equation correspondence, multiplicity, translations, end behavior.
Interpreting growth/decay rate, rewriting exponent forms, comparing linear vs. exponential change, percent-change parameters in context.
