In the univariate analysis, several demographic and academic characteristics of the 2324 students predicted a higher grade on the test, including male sex, older age, French citizenship, being non-granted, parents’ profession (senior managers and intellectual professions followed by business owners, middle classes and then employees), repeating the year, attending a scientific high school, receiving honors at the exit examination and having responded to the questionnaire (Table 5). In the multivariate analysis, the same factors remained significant, except for French citizenship, parents’ profession and question- naire response.
