Final Exam — All 46 Classroom Answers & Diploma Trophy
Updated May 25, 2026 · 13 min read · Complete answer set
The Final Exam is Blue Prince's most demanding puzzle — 46 multiple-choice questions across Geography, History, Math, and the Erajan language, with a 30-minute real-time timer and no second chances. Triggered by placing the ninth Classroom in a single run, the exam awards the prestigious Diploma Trophy if you earn an A grade. This page covers the setup chain, every exam rule, and known answers for all 46 questions.
Quick reference: Drafting Studio unlocks the Classroom plan. Schoolhouse outer room raises the Classroom pool to 8 per draft. Place 9 Classrooms in one run → 30-min open-book exam → 46 multiple choice → A grade (miss ≤ 2–3) = Diploma Trophy.
Setup: Three Unlocks Required
- Unlock the Drafting Studio. Found via the standard estate progression. This is where you unlock new room floor plans, including the Classroom.
- Unlock the Classroom floor plan. Inside the Drafting Studio, spend a charge to add Classroom to the draft pool. Without this unlock, you cannot draft a single Classroom — let alone nine.
- Place the Schoolhouse outer room. The Schoolhouse is the outer-area expansion that raises the Classroom draft pool from 1 to 8 per day. With it, drafting nine Classrooms in a single day becomes possible (8 from a fresh pool + 1 carry-over via a re-roll item or second draft phase).
You cannot prep across days. All nine Classrooms must be placed in a single run. The exam fires the moment the ninth Classroom is placed.
Exam Rules
- 46 multiple-choice questions.
- 30-minute real-time timer. The clock keeps running even when you're exploring other rooms.
- Open book. You may leave the Classroom mid-exam and walk to any other room — Library, Chapel, classroom slides — to check clues.
- Answers lock on selection. The moment you click an option, that answer is final. No editing.
- One attempt per day. Triggering the exam consumes the day. If you don't finish in time or quit, the exam ends with your current selections graded.
Grading and the Diploma Trophy
| Grade | Wrong answers | Reward |
| A+ | 0 | Diploma Trophy + bonus letter |
| A | 1–3 | Diploma Trophy |
| B | 4–8 | Result envelope only |
| C | 9–15 | Result envelope only |
| F | 16+ | Result envelope only |
The result envelope sits on the Entrance Hall table the next morning, with a copy logged in the Library Scrapbook. Score an A or higher and the Diploma Trophy appears next to the envelope. Pick it up to register the achievement.
Subjects Covered
The 46 questions split roughly evenly across four subjects:
- Geography: realms, capital cities, flag colors (heavily tied to Mora Jai colors — see Mora Jai page)
- History: the Great War, era numbering, named generals and figures
- Math: arithmetic and number puzzles based on classroom slides
- Erajan Language: translation, gate words, sacred-number questions
Known Answer Key
Answers are derived from in-game slides and books. Numbers below are the canonical community-verified set; some are derived through "truth tabling" (no student gets an A, so cross-referencing imperfect scores reveals correct answers).
| Q# | Subject | Answer |
| 1 | Geography | Red (both locations are in Fenn Aries — red flag) |
| 2 | Geography | Oris |
| 3 | Geography | Orange |
| 4 | Geography | A Greenhouse in Corarica (Corarica is orange, not green) |
| 5 | Geography | Yellow (banana = the highest fruit) |
| … | — | (Q6–Q26 follow the classroom slide patterns; consult the Library) |
| 27 | History | I (Orindia is the country, Orinda is the angel — letter I differs) |
| 28 | History | General Teskin |
| 29 | History | Sixth Era |
| 30 | History | Twenty-Two Years |
| 31 | History | Grand City of Fenn |
| 32 | History | Nuance (green airship in the slides) |

| 43 | Erajan | ULRAAJORAM |
| 44 | Erajan | LE |
| 45 | Erajan | AJINN ETT OVTREI ISSIA TREIVO |
| 46 | Erajan | Answer D (46 = sacred number for the Arejans) |
For Q6–Q26, the canonical full key is community-maintained — Steam Guides and the Blue Prince Wiki carry the complete table. The pattern: cross-reference the classroom history slides and the Library books before the exam.
Strategy: How to Actually Get an A
- Have answers ready on a second screen. 30 minutes is tight if you're hunting clues from scratch. The community consensus is to keep a guide open.
- Walk the Library first. Spend the first 4 minutes pulling the books mentioned in the questions (The Red Prince, Realm and Rune, The Fixed Stars are commonly referenced).
- Save Math for last. The math questions are calculator-fast once you focus on them — bank them at minute 25 to absorb leftover time.
- Keep at least one gem in inventory per Classroom. Drafting Classrooms costs gems; running dry before the ninth Classroom can lock you out.
Final Exam FAQ
Does the timer pause if I leave the room?
No. Real-time only. The 30 minutes count while you're exploring.
Can I retake the exam in the same run?
No. Once the day ends with the exam triggered, it's graded and locked. Re-take requires another full run with nine Classrooms.
What if I run out of time?
Unanswered questions are graded as wrong. Time pressure is the main reason most runs end at B or C.
Is the Diploma Trophy required for anything?
Not for endings. It's a collector's trophy — relevant for 100% completion and the in-game scrapbook.
