Around 20-30 per topic. Past 40 you are mostly re-testing what you already know.
| Questions done | Typical accuracy | Verdict |
|---|
| 5 | 40-55% | Too few to judge |
| 15 | 60-70% | Gaps visible |
| 30 | 75-85% | Good stopping point |
| 50 | 80-88% | Diminishing |
| 80 | 82-90% | Time better spent elsewhere |
