Jiang Si wasn't in a rush to skip class to find the cripple.
If the other party really wanted to fight, they wouldn't leave easily, no need to hurry. These few Chinese and English classes, he would use to focus on reviewing, basically not listening to the teacher's lecture.
He always felt that honestly listening to the class was the slowest way to learn, especially Chinese and English, with a bit of a reputation for being repetitive and time-consuming.
These subjects were most efficiently remembered actively by himself. He only went to school three or four times a week, attended very few classes, but he seriously reviewed the content he had forgotten from previous classes, actually already starting on the third year high school material.
His progress was much faster than those who listened in class, of course, also because he had learned everything once before, making his review more efficient was normal.
