| 70% (C-) | 20% | 94% |
| 70% (C-) | 30% | 84% |

Pro Tip
If partial credit is available, always attempt every question — even a partial answer is better than blank. For multiple choice, eliminate obviously wrong answers first; statistically, guessing from 2 remaining options gives you 50% odds. Time management matters: skip hard questions and come back to them.
