What TSI Practice Prep is
TSI Practice Prep is an independent, original-content practice platform for the Texas TSIA2, the Digital SAT, and the ACT. Every practice question is written by TSI Practice Prep rather than copied from an official, previously administered test. Practice includes full explanations, choice-by-choice reasoning, mistake-pattern tagging (concept gap, process error, reading trap, pacing/guess), pacing tools, and a Teacher Classroom mode for live, in-class practice sessions.
What it is not
TSI Practice Prep is not the College Board, ACT, Inc., or the Texas Higher Education Coordinating Board, and it is not affiliated with or endorsed by any of them. Practice scores shown here are learning estimates based on TSI Practice Prep's own questions — they are not official TSIA2, SAT, or ACT scores, and they do not guarantee any admission, placement, or graduation outcome. Official exam registration, current test structure, and official practice materials should always be confirmed directly with College Board, ACT, or the relevant Texas education agency (see Resources).
Who it is for
Students studying independently, and teachers who want a shared practice set with live progress visibility and error analytics for a class or tutoring group (see Teacher Classroom).
