1 Changes and clarifications to the Higher Level Syllabus
Changes to the IB Higher Level Mathematics SyllabusFirst Examinations 2014Big overall changes are that matrices (12 hours of teaching time) have been removed. The two portfolio pieces have been replaced by a more open-ended mathematical exploration. Applications are mentioned much more than previously.
