20 12 is Mianyang xiaosheng junior high school easy to take the exam? I am poor at math, and I often get more than 80 points. I know nothing about the Olympics. I just need to work harder on English and Chinese.
Nice test.
How can we improve our grades?
Preview before class, know the content of class in advance, and the teacher will be handy as soon as he teaches.
Review in situ after school ...
If it is good, fill it up. O(∩_∩)O
