One of the toughest challenges in Blue Prince is conquering the Classroom final exam. It’s not just about answering questions—you’ll need to plan ahead, manage your rooms wisely, and uncover key clues. This guide walks you through everything required to earn an A (or higher) and unlock the coveted Diploma Trophy.
Diploma Trophy Requirements – What You’ll Need
To achieve the Diploma Trophy, you’ll need to meet several conditions during a single run:
-
Draft nine Classrooms within your manor.
-
Complete the final exam within the time limit.
-
Note: Once you select an answer, you cannot change it.
This challenge demands both strategic room placement and accurate knowledge across several subjects.
Getting Started: Drafting Studio & Schoolhouse Essentials
To begin, make sure you can draft Classrooms:
-
Drafting Studio – Unlocks the Classroom room type.
-
Schoolhouse – Placing this outer room allows up to eight Classrooms to appear in the day’s draft pool.
Together, these two unlocks make it possible to place the required nine Classrooms in a single run.
Nine Classrooms, Hundreds of Clues
Each Classroom serves as a “grade level” tied to a specific subject that appears in the final exam. Here’s how to prepare:
-
With the Drafting Studio and Schoolhouse, aim to place nine Classrooms.
-
Each one costs 1 gem, so plan your resources carefully.
-
You don’t need to place all nine at once, but you must have nine total before reaching the final exam.
Subjects covered include:
- Color
- Art
- Science
- Geography
- History
- Math
- Algebra
- Erajan Language
Some of these rooms also offer hints for puzzles elsewhere in the game:
-
Math & Algebra aid with the Billiards/Darts Puzzle.
-
Art reveals clues tied to the Pairs of Paintings.
-
Geography & Erajan provide insight into the Castle Cipher puzzle—and even hint at deeper late-game secrets.
Facing the Final Exam
The ninth Classroom you place will contain the final exam, testing your mastery of all prior subjects.
Here’s what to expect:
-
46 multiple-choice questions
-
A 30-minute timer to complete them all
-
Answers cannot be changed once selected
-
You’re allowed to leave the room to revisit earlier Classrooms for reference
Pro tip: Carefully explore and absorb each Classroom’s content beforehand to avoid losing precious exam time.
