Algebra transfers. Adaptive SAT timing, Bluebook tools, and SAT Reading-and-Writing modules do not. Give yourself two or three weeks of enhanced ACT clocks before the first official sitting. You are changing the exam, not starting from zero.
What you can keep
- Linear equations, functions, and geometry facts.
- Grammar rules that also appear on ACT English.
- The habit of an error log.
Format differences that still matter: enhanced ACT vs Digital SAT.
What you have to relearn
- Linear, non-adaptive sections. You cannot get an easier second module.
- English 50/35, Math 45/50 (four choices), Reading 36/40, four single passages.
- Optional Science if any college on the list wants it.
- Paper or digital ACT tools, not Bluebook. Digital ACT tools.
A two-week switch plan
Day 1: full enhanced core diagnostic. Days 2–10: daily timed section on the weakest ACT score. Days 11–12: one more full test. Day 13–14: review only. Do not keep mixing SAT modules in the same week—the clocks fight each other.
Science and STEM
SAT has no Science section. If you are switching because you want to show science reasoning, sit optional Science only if a campus will read it: ACT vs SAT for STEM majors.
The bottom line
Keep the math. Throw out SAT pacing. Prove the switch with one timed ACT before you pay for a new official date.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
