300 points. According to the information of Chaling County Education official website, Xiao Sheng ranked 60th in Chaling County, Zhuzhou City, Hunan Province, and scored 276 points in the final exam of Grade 6. A score of 240 in the junior high school exam is average, and a score of 260 is better. Only when the total score is above 290 can it be rated as excellent. Because primary school knowledge is relatively basic, so the score will be higher. The senior high school entrance examination is divided into Chinese, mathematics and foreign languages, with a total score of 100, totaling 300 points, so the full score of the senior high school entrance examination is 300 points.
