Every question explained in full — the rule, the shortcut, and why each wrong answer was written to catch you. Built for students, not for billing hours.
The same course, the same explanations, wherever a student sits it.
SAT® and PSAT/NMSQT® are trademarks registered by the College Board, and ACT® is a registered trademark of ACT, Inc. Neither organization endorses, sponsors or is affiliated with this course, and neither was involved in producing it. Score bands, percentiles and ACT equivalents are drawn from the published concordance and from institutions’ own scholarship tables; they move slightly from year to year and from one university to another, so treat every figure here as a guide and confirm the current one with the institution before making a decision on it. No particular score is promised: the only outcome commitment we make is the Completion Standard, whose conditions are set out in full on the Course process page, and it is a commitment to extend access or refund the fee — never a prediction of a result.
