My classmate Tang San was always at the top of his grade in exams every time. No matter whether he was major exam, small exam, monthly exam or mid-term exam, he was always so good, while I followed closely, like this every time, never surpassing him. No one remembers the second place, unless like me, I always sit in second place. Today, teacher Wang, the head teacher, started to announce the results again, and this time the ranking is still the same. I really want to know what kind of learning secrets my classmates have to be so good. . .
