Holidays are not for rest, but for overtaking. Learning is like sailing against the current. If you don't advance, you will retreat. Many people won the holiday and many people lost it. The following is our holiday life: after getting up in the morning, we started a day of study after breakfast. Except for eating, going to the toilet and having a short rest after dinner, we will never leave our study table from morning till night. From mathematics to physics, chemistry to biology, before the start of school, I looked at four textbooks with three colors and repeatedly pondered textbooks, and felt that the holiday was full of practicality and pride.

Of course, during the holidays, we not only do problems, but also have our own unit tests. Every unit with 85 points needs to be repeated. When there were no test questions, we went to the bookstore to "scrape books", but we didn't buy them. After 85, proceed to the next unit. All these efforts will not be in vain. After school, we haven't accepted the confusion and pain of new knowledge, and everything has become so natural. This looks terrible, but it is so real to most students in Tsinghua. Look at those students who haven't finished their homework or copied it at last, and you will understand how big the gap is during a holiday. Many times, a person is ahead not because he has a longer brain than others, but because he is not at the starting line with others.
