I won the second place in the exam in 2007, which was a particularly difficult year. We were the first students in three semesters, and we all failed in the second. . .

Of course, if you have a strong learning ability, you can still work hard. Some of us have never studied linear algebra, but only learned high numbers. The linear algebra taught ourselves to take the second number, 130.

It seems that counting three is also wired, and counting three is always more difficult than counting four.

Come on ~ ~ good luck.
