"I know I want to study. Isn't it difficult to hide my enthusiasm after a summer vacation?" Shi Sang said seriously, "It's not too late for you to study again later."

"It's too late." Xie Yan's eyes drooped, and wrote two formulas under the tip of his pen, and said lazily, "If you don't study today, you will become garbage tomorrow."

“…”

"It is learning that has given me an elegant and calm life. You can let you down, and I learn from my practice, but in the end it is your own trash."

“…”

As a garbage man, Shi Sang twisted his head speechlessly.

At seven o'clock, the class ringtone rang on time.

The slight movement in the class disappeared in an instant. Several level directors who were inspecting each class nodded with satisfaction and slowly went to the next class with their hands behind their backs.

Although the formal classes have not started yet, teachers of various subjects have sent many test papers. Lin Er is working on a physics test paper, and the finale question on the test paper gave her a headache.

Unlike Xie Yan, who almost got full marks in the associate subject, her three subjects of science and science are not good. Although her grades are good compared to ordinary classes, she is only at an average level in this class.

The scores of the science comprehensive science of Class 1 are quite fixed. Students with better grades can get more than 28, while students with worse grades will step on the threshold of 27, neither up nor down, while most of the average level are stuck between these two score lines and swaying left and right.

Liner is the one who wanders left and right.

After changing two formulas in a row, but the answer was not calculated. Lin Er poked her face with a headache. This question had been stuck for nearly ten minutes.

She bit her pen cap, stared at the topic for a while, but turned her head and poked Xie Yan.

Xie Yan held a slender pen in his hand, and he was writing something in the textbook from time to time. His eyes were still on "May 3", and he leaned against her and whispered, "Huh?"

Liner watched him finish writing the formula before pushing the physics test paper in front of him, saying, "I can't do anything about it."

Because she was in self-study class, she kept her voice very low.

"Let's take a look." Xie Yan's eyes fell.

"This question." Liner pointed to him, "The first and second questions were asked, but the third question could not be calculated."

Xie Yan glanced at the topic and looked down.

His gaze flew past the two answers she asked for, and then his eyes stopped slightly at the answer to the second question.

"It's not right here." Xie Yan turned sideways, pointing the tip of his pen below the answer, "You don't need this formula. Look at the first question you asked for, this is a hidden condition."

As soon as he hooked his pen tip, he quickly wrote two more formulas in the blank space next to him.

"Try these two?"

"Oh." Liner wrote down as he thought.

As soon as I finished my first move, the class shouted "ao" and listened to the sound, and it was still a boy.

Lin Er was shocked by this sudden "Ao". The tip of the pen in his hand shook. The end of the letter "f" that was writing could not hold back. A long tail was dragged out from below, almost cutting through the thin paper.

Lin Er stabilized his skills and continued to write without distraction.

As a result, as soon as the word "v" fell, another thrilling voice "Ah!!!" resounded throughout the classroom.
