In 2021, Hunan Province's new college entrance examination biology was a re-elected subject. Each re-elected subject was originally divided into 100 points. When converting, 30 points were used as the starting point for the grade conversion, and 100 points were full marks.

The proportion of people in each grade was about 15%, 35%, 35%, 13%, and 2%, respectively. The corresponding score range was 100 - 86 points for Grade A, 85 - 71 points for Grade B, 70 - 56 points for Grade C, 55 - 41 points for Grade D, and 40 - 30 points for Grade E.

However, based on the original score of 70 points, it was impossible to know the exact score after the score was assigned. This was because it still needed to be converted according to the principle of proportional conversion and the original score of other examinees in the same grade. The conversion result would be presented as a whole number according to the rule of "rounding". <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
