More than 90 points are excellent, and more than 95 points are excellent and careful.

Above 95 points, there is no problem in junior high school mathematics (good foundation).

80 points can only be said to be hard work. The most relaxed statement is that primary schools with 85 points or above are excellent in mathematics. Anyway, 80 points can only be good or not, so we must work hard. (In junior high school, you will find a river between 95 and 96 and a ravine between 99 and 100) (In fact, the full mark of junior high school is generally not 100, so I just give you a rough example).
