### 1/5 — So bad

*2026-07-18*

Gives wrong answers.

**Developer response:** You were right — there was a rounding tie bug in percent and money calculations that could mark correct answers wrong. That is completely fixed in version 1.0.2, and we verified every question generator across 200,000 test cases. Give the update a try.
