Who succeeds in advanced mathematics and science courses?

Few students (particularly few girls) currently choose to take their Final School Examination (FSE) in advanced mathematics, chemistry and physics, a combination of subjects that is the best preparation for a science-oriented study in higher education. Are these subjects attainable by more students than is currently the case? This study examined 6033 students in upper secondary education, including 720 students who took their FSE in advanced mathematics, chemistry and physics. The results show that the latter group (and in particular the girls in that group) had higher scores on math ability than students who chose other examination subjects. Regression analyses demonstrated the relative importance of math ability and achievement motivation for attainment in these science subjects. However, an expected positive effect of homework time as well as possible mediating and moderating effects of the predictors could not be confirmed
