The history undergraduate course line is a 30 1 2 examination style implemented by the new college entrance examination reform. Candidates take the national unified examination of Chinese, mathematics and foreign languages, mark them in the total score with the original score, and then choose a subject in history or physics, and mark them in the total score with the actual score. Finally, in geography, politics, chemistry and biology, two subjects are selected to take the college entrance examination, and the results of these two subjects are included in the total score. The total score outside the number of languages is 450, and the other three subjects are 300. The results of the college entrance examination with history as the preferred subject have reached the batch line of undergraduate admission, also known as the history undergraduate line.
