Everything Teachers, Students & Parents Ask

Photo-solver apps just output algebraic steps, which encourages passive copying. UNTRAP diagnoses the distractor: it explains why the question writer planted the wrong option you picked, what cognitive slip occurred, and how to spot that trap structure on future exams.

Teachers use UNTRAP to pre-screen practice worksheets for hidden traps, quickly diagnose why a student missed questions during tutoring, and explain high-frequency distractor archetypes to their classes.
