Life in the third year of high school is always busy and tense.

When I arrived in the classroom, I found that more than half of my classmates had already arrived. Some were reciting English, some were reading Chinese, and no one was slacking off. This is the atmosphere of the key class.

I also hurriedly sat down and took out my textbook from my schoolbag to start my morning reading.

Fortunately, in my previous life, after graduating from normal college, I passed the examination and entered a high school to teach English. I am not unfamiliar with the textbooks, but I have forgotten a lot of the science knowledge in high school.

There was a test on physics, chemistry, and biology in the morning. When the test paper was handed out, I read through it several times from start to finish and finally realized that I wouldn't be able to answer at least half of the questions.

I was extremely distressed. It was already the second semester of the third year of high school, and I didn't have much time left. What should I do?

"Yelin, stop daydreaming and start doing the test paper." My classmate knocked on my arm, reminding me.

"I'll do it right away." After saying that, I forced myself to start writing one question after another. Two hours passed, and I only finished half of the test paper.

In the end, I didn't hand in the test paper. I was afraid that the teacher would start to suspect me because my previous grades were still considered good.

Because I was worried about how to quickly improve my grades in physics, chemistry, and biology, I didn't immediately go home after school in the afternoon, but went to the pavilion next to the playground.

After many years, sitting in the pavilion again, my heart couldn't help but be filled with mixed emotions.

After a while, I heard footsteps behind me. When I turned around, it was Cheng Nan.

He held a cup of coffee in his right hand and a book in English in his left hand. He sat on another stone bench, calmly reading the book.

At that moment, an idea suddenly came to my mind. Why don't I ask him for advice on how to study physics, chemistry, and biology? After all, he's a genius who scores full marks every time.

If it were the me from my previous life, I might not have had the courage, but in this life, I've promised myself to be a brave Yelin.

"Hello, Cheng Nan, I'm Yelin from Class 2 of the third year of high school. Can I ask you a few questions?"

I involuntarily grabbed the hem of my school uniform with both hands, stood in front of him, and nervously waited for his answer.

I looked up at him, and he looked at me, then lowered his head to read his book again. Just when I thought he had rejected me, I heard him say lightly, "What's the question?"

I was extremely happy. I tried to calm down my emotions and asked him, "Since you're so good at physics, chemistry, and biology, can you tell me what method you use to study them?"

He seemed surprised that I would ask such a direct question. After hesitating for a while, he replied, "Isn't your performance in physics, chemistry, and biology also good?"

I didn't know how to explain it now. I couldn't say that I had forgotten all the knowledge in physics, chemistry, and biology.

All I could do was to lie and say, "I have a classmate who isn't very good at physics, chemistry, and biology. I want to know if there is a fast way to improve their grades."

"If you want to learn physics, chemistry, and biology quickly, you should first build a solid foundation, familiarize yourself with the knowledge points in the textbooks, and then learn how to apply them to other problems."

"Is it that simple?" I couldn't believe it.

Cheng Nan didn't seem happy with my skeptical attitude. He slightly furrowed his attractive eyebrows and said displeasedly, "If it wasn't that simple, how could physics, chemistry, and biology be easy for some but difficult for others?"

I didn't dare to argue with him anymore. I could only nod reluctantly to show my agreement, say goodbye, and leave.

When I returned home, I carefully thought about Cheng Nan's words. I took out the physics, chemistry, and biology textbooks from the first to third year of high school and planned to study them one by one.

After staying up late for half a month, I finally grasped the basic knowledge of physics, chemistry, and biology throughout three years of high school. When I took the test paper, I wouldn't panic as much.
