Generally, the score of chemistry 50 is about 55-65. The specific score depends on the actual position and overall level of the examinees in that year. The calculation of the scoring system of the college entrance examination is a scoring method under the new college entrance examination mode, which is mainly used in provinces implementing the "3+1+2" mode of college entrance examination.
50 points in chemistry exam How many points can you give
The score of 50 points in the chemistry exam is not necessarily many, but depends on the situation.
The calculation of the scoring system of the college entrance examination is a scoring method under the new college entrance examination mode, which is mainly used in provinces implementing the "3+1+2" mode of college entrance examination. There are 3 steps:
1. Determine the scoring range. The original scores of the examinees in each subject are arranged from high to low, and the five grades A, B, C, D and E are divided according to a certain proportion. The corresponding score ranges are 100~86, 85~71, 70~56, 55~41 and 40~30 respectively.
2. Determine the original score range. Corresponding to the assigned area, the original score range is determined by the number of people actually taking the exam in each subject and their scores.

The calculation of the scoring system of the college entrance examination is a scoring method under the new college entrance examination mode, which is mainly used in provinces implementing the "3+1+2" mode of college entrance examination. There are 3 steps:

2. Determine the original score range. Corresponding to the assigned area, the original score range is determined by the number of people actually taking the exam in each subject and their scores.
3. Use the formula to calculate. Let the difference between the maximum value of the original score interval and the original score interval be R, the difference between the original score interval and the minimum value of the original score interval be r, the maximum value between the assigned areas is A, the minimum value is a, the score of the assigned points is the unknown number T, and the rest are known numbers. The scoring formula is R/r=(A-T)/(T-a). After calculation, the value of T can be obtained by rounding off.
For example, Zhang San chose chemistry and politics as his subjects and scored 90 and 89 respectively. The final scores included in the college entrance examination are not 90 and 89, but may be 95 and 80, which is due to the calculation method of the scoring system.
