his little candy

The chemistry teacher sent out a test paper, focusing on the derivation training of the chemical experiment process.

The lower the temperature, the smaller the solubility of sodium bicarbonate, which is easy to precipitate.

As soon as Song Guo finished answering, Su Ruan's small note was thrown on his desk.

Song Guo looked up at the drowsy chemistry teacher who was sitting on the podium wearing glasses, and uncovered the ball of paper in a concealed manner.

Su Ruan: Xiao Guoguo, are you at home or where are you going to play on weekends?

Song Guo: In class.

Su Ruan threw a small note over again: Xiao Guoguo, let's go to the movies, shall we?My goddess has a new movie, I must support it!

Song Guo was helpless: Alright, I'll go with you.

Su Ruan couldn't control her excitement, and the chemistry teacher on the podium almost groaned in shock, and almost hit the edge of the podium with her tilted head, and there was a puffing sound from below.

The chemistry teacher stood up angrily, glanced at the clock above the classroom screen, blew his beard and stared and said, "What are you laughing at, I'm done, then I'll collect the test papers."

In less than 10 minutes, he had to do dozens of difficult chemical experiment questions. This is Song Guo, who was the fastest to solve the questions, and only made it to the last side.

"Teacher, don't, we haven't finished yet."

"This question is so difficult."

"I haven't finished the first few courses."

There was a lot of wailing below, and the chemistry teacher snorted coldly, "If you don't consolidate your basic knowledge, it will show its original shape now."

Someone muttered in a low voice: "You are so cute, this is still basic knowledge!"

The chemistry teacher turned around in the aisle, walked up to Song Guo, picked up his test paper, squinted as if he couldn't see clearly, then took off his glasses, bent down and picked up a stack of clothes, wiped the lenses, put them on Finally, read the test paper over and over again.

Song Guo felt a little nervous in his heart, but actually there was also a little bit of joy.

Four to 10 minutes, about the level of the students in the class can only finish a few questions, but he only has the last few questions left.

The source of the title is marked on the question, which is all selected from the last few big questions from all over the country over the years, so the difficulty should not be underestimated.

Song Guo suppressed his excitement and waited for the chemistry teacher to speak, but the teacher calmly folded up the test paper and returned it to him.

Song Guo's heart sank suddenly, looking at her test paper, the voice of the chemistry teacher rang out from the podium.

"This test paper has four 10 minutes. After finishing all the questions, I will give you another 10 minutes. After 10 minutes, the class will be over. The class representative will put away the test paper and bring it to the office for me."

After the chemistry teacher finished speaking, he left with a stack of unfinished test papers.

Su Ruan raised her head from the test paper, saw that she had written the goddess in the place where the derived inorganic equation should be filled in, then tapped her head with the tip of her pen, complaining to herself, "Oh, it's hopeless."

"Goddess, please give me a koi so that I can pass the chemistry exam."

After Su Ruan finished praying, she glanced at the questions she hadn't finished, then slumped on the table dejectedly, looked at Song Guo next to her, saw his blank eyes, and said puzzledly: "Little Guoguo, What’s wrong with you?"

Song Guo shook her head, looked at the test paper again, and focused on the questions.

After 10 minutes, Song Guo was the only one who finished.

He handed in the test paper amid the envy of his classmates, but there was no look of joy on his face.

After hearing what the chemistry teacher said, Song Guo felt complicated, mostly frustrated.
