Harry Potter and the Great Old Ones

Meanwhile, at Hogwarts, the largest wizarding school in Britain.

Harry, Ron, Hermione, and of course, one of Tyrell's alter egos, were sitting in the Great Hall of Hogwarts, furiously writing on their Dark Arts exams—

This year's magic exam was full of innovation.

First, the Dark Magic exam was divided into Paper A and Paper B.

Paper A is a science paper, consisting almost entirely of long calculation problems, and the exam lasts four hours.

Paper B, on the other hand, was a humanities paper. The main exam content included ancient rituals, classical dark magic priesthood, and the history of dark magic. The exam lasted two hours, so while Harry, Ron, and Hermione were frantically writing and calculating in the classroom, a somewhat noisy discussion could be heard outside the door—

The students who used the black magic B-version exam have already finished, while the students who used the A-version exam have only completed half of their exam time.

Inside the classroom, Harry frowned, intently calculating the questions on the test paper.

He silently calculated in his mind while using calculation magic to calculate the values, minimizing the possibility of errors.

Ron rubbed his temples vigorously with one hand, trying to concentrate, while flipping through his books and notes, making an annoying rustling sound.

—The Dark Arts Exam A is an open-book exam. Apart from exchanging answers with each other, it is not forbidden to bring any notes or books to the Dark Arts Exam A.

If you have the ability, you can even summon a demon, seal it inside your notebook, and let the demon finish writing the text for you.

So, a tall stack of books and notebooks was piled on Ron's exam desk—notes he had traded from other students with his treasured wizarding cards before the exam. Hermione, on the other hand, was engrossed in the fascinating calculations of the Dark Arts exam. Her desk was completely empty except for the exam paper, ink, pen, and a few sheets of scratch paper. She answered each question with ease, and now Hermione only needed to finish the last three major questions.

Clearly, the Dark Arts Exams Paper A posed a significant challenge for Harry and Ron. Their strength lay in practical magic, and these complex calculations proved somewhat difficult for them.

As for Tiera
These questions were set by Tiera.
He only came to the exam to go through the motions and get a perfect score.

The noise coming from outside the exam room was getting on Harry's nerves, while Ron just gave up and threw his pen on the table and slumped into his chair.

"I should have chosen the B version of the exam!" Ron muttered to himself.

"It's not like you can memorize the entire B-version exam." Hermione, who was writing furiously, suddenly paused, looked up, and said. After teasing Ron, Hermione lowered her head again and continued calculating the problem in front of her.

Just like the teasing of Ron was a spice in the middle of the exam.

“Look on the bright side, Ron,” Harry said softly. “After this exam, we can go on a trip with Mr. Weasley.”

There were no proctors for the Dark Arts exams; instead, an automatic proctoring spell developed by Tyella and a group of young German wizards was used.

Tierra's inspiration came from her analysis of the Sorting Hat's magic.

Within the scope of this magic, students are allowed to chat about things unrelated to the exam. However, once the magic detects that they are discussing problem-solving strategies or other exam-related topics, it will immediately record the conversation and send the student and their exam paper to the classroom where the invigilators are located, for the invigilators to decide.
