Meaning he has completed calculus? If so, why not defer statistics to 12th grade so that he can take honors English?
Economics or finance will require statistics, but some colleges require calculus-based statistics for those majors. Also, many science or engineering majors that require statistics will require calculus-based statistics or a major-specific version. So AP statistics may not be as useful for subject credit as one might assume.
Instead of statistics, can he take economics junior year in order to determine how interested he is in economics?
