- Worth noticing
- A low-confidence answer is held back; each posted answer shows its source and when it was last changed.
Field notes
The review process requires two independent solutions to reach the same answer before it is labeled provisional; a teacher can then approve it, and a match with Inep's key earns the official label. The page also compares results with 2025 subject averages drawn from more than 3.1 million participants, switching to its own user average once an area has 30 checked exams. The site says ENEM Certo is not affiliated with Inep.
