Field notes
The example shows the feedback at line level: after a student expands 2(x + 3) = 10, the app identifies an incorrect move and gives the correction, 2x = 10 − 6. The page lists diagnostics, targeted practice, and weekly parent reports alongside the current Grades 7–12 Korean curriculum library. Weekly report texts require a Korean mobile number; IB, SAT, and AP courses are presented as future offerings.
