Looking at the test paper that Tierra took out, Harry suddenly felt a sense of endless despair.

But when Harry looked up at Tierra's unwavering gaze, he knew he couldn't escape, and Tierra must be determined to let him finish these questions.

"Okay, okay...I, I, I will try my best to do these subjects." Harry said helplessly, then shook his head trying to cheer himself up.

But it was quickly resisted by a warm palm.

"Just shaking your head won't increase the knowledge in your mind." Tierra joked, "Practice will increase the knowledge in your mind. Come on, Harry, start with this question first."

Tierra's slender fingers pointed at the test paper that was now on Harry's desk.

Harry followed Tierra's fingers, and his eyes began to fall on the test paper. He read the content of the question painfully and slowly, and tried hard to recall the content of Tierra's class, trying to understand the mathematics and the concept of dimension.

Harry thought about the solution to the problem, and then began to calculate on the test paper with his pen.

After about ten minutes, Harry stopped writing, paused, and then continued to write a few strokes, and then—

Harry raised his head cautiously, trying to see what Tierra was doing.

"Ah...you, you, you, do you still...um...you can't solve any of the problems..." Harry said nervously, "you forgot how to solve it...you mean you wrote it down in your notebook, but did you bring your notebook?"

"Half an hour, Harry, it's already half an hour." Tierra walked over, reached out and tapped Ji Yi's paper, "He just wrote a question."

"But that question is still wrong." Tierra picked up the paper and said before scanning it day by day.

The time passed by like a minute and a second, and the ticking sound of the modern clock under the wall became the only source of sound in that quiet classroom.

Ji Yi raised his head to calculate the question for a while, then raised his head to look at Tierra again, raised his head to calculate the question for a while, then raised his head to look at Tierra again.

Tierra was sitting on the high chair behind the podium, holding a book and reading quietly, with the corners of her mouth slightly turned down, always with this calm and serious smile.

"Ah...yes, what's the matter, it's not that question...it's too difficult..." Harry said with a blushing face.

"Use Taylor to unfold." Before Tierra said something flutteringly, he raised his head and continued to read the book under his hand, "During the exam, he is allowed to bring notes and other review materials. He has to get used to that way."

"What are you doing? Don't you have an answer under your face?" Tierra reluctantly closed the book outside her hand, and then threw it heavily under the podium.

"You, you, you, you, you..." Harry seemed to be stuttering.

"Uh...bad, bad..." Harry raised his head somewhat at a loss, and wanted to continue solving the problem, but he knew why, and I always felt that I was in a mess.

"You understand the pressure on his shoulders, but knowledge changes destiny, Harry," Tierra said.

The early morning sunlight in midsummer reflected in through the mottled windows of the black magic classroom, as if coating everything in the classroom with a thin layer of gold.

"What? Finished? So slow?" Seemingly noticing Ji Yi's gaze, Tierra lowered her eyelids and looked at Harry with agile eyes.
