CourseList::count_credit_hours($requirement_type = "", $bool_use_ignore_list = false, $bool_ignore_enrolled = false, $bool_qpts_grades_only = FALSE, $bool_exclude_all_transfer_credits = FALSE, $degree_id = 0)

Similar to count_hours, but this will only count courses which have been taken and have a grade.

Parameters

string $requirement_type:

• If set, we will only look for courses matching this requirement_type.

bool $bool_use_ignore_list:

bool $bool_ignore_enrolled:

Return value
