The score distribution is a way to represent the scores of candidates in a specific subject. Typically, these scores are presented in the form of a chart, with one axis indicating the score and the other axis indicating the number of candidates who achieved that score. Fig. shows the analysis of the 2022 national high school graduation exam results in Chemistry shows that there were 327,370 candidates taking the chemistry exam, with an average score of 6.7 points and a median score of 7.0 points. The most common score was 8.0 points. There were 43 candidates with a score of ≤1 (0.01%); and 49,900 candidates with a score below the average (15.24%). The score distribution is published annually by the Vietnamese Ministry of Education and is displayed as a chart for each subject. The score distribution is used to classify the level of proficiency and ability of candidates and to evaluate them based on predefined standards. It is also used to test and evaluate candidates according to a certain standard and to classify test papers by difficulty level, thereby evaluating the quality of the candidates. We collected score distributions from 2019-2022 . By comparing the results of large language models with the results of Vietnamese students, we can evaluate the ability of LLMs.
