"What a pity, just two points away from the target," Li Zheng said with a smile as he compared the two test papers. "But I haven't been working too hard on physics lately. You'll earn those two points soon. Here, let me go over the mistakes with you."
"Don't need your explanation," Zhang Xiaoke straightened up and snatched the paper back. "I already understood it when I compared the answers earlier."
"Really? Then it looks like you're smarter than me," Li Zheng nodded confidently. "At this rate, there's a good chance you'll reach the midterm goal I set for you."
With that, he pushed two exercise books towards Zhang Xiaoke. "Focus on these two books for the next couple of days, and feel free to challenge me anytime."
"You just wait. I'll pass by nightfall," Zhang Xiaoke took the exercise books and glanced at the towering pile of books. "You spent quite a bit on these, huh?"
"Yes."
