In particular the Standard one replaces
"Students of the Mathematics Standard 1 and Mathematics Standard 2 courses study a common Year 11 course, Mathematics Standard Year 11, leading to the Mathematics Standard 1 Year 12 and Mathematics Standard 2 Year 12 courses. Schools have flexibility in providing alternate approaches to Mathematics Standard in Year 11 to address material essential for Mathematics Standard 1 in Year 12. This material is denoted by the symbol ◊. Students who follow the ◊ pathway in Year 11 Mathematics Standard will only be eligible for Mathematics Standard 1 in Year 12."
with
"Students studying the Mathematics Standard syllabus undertake a common course in Year 11. For the Year 12 course students can elect to study either Mathematics Standard 1 or Mathematics Standard 2. Students who intend to study the Mathematics Standard 2 course in Year 12 must study all Mathematics Standard Year 11 course content. Students who intend to study the Mathematics Standard 1 course in Year 12 must have studied the content identified by the symbol ◊ which forms the foundation of course. This content is important for the development and consolidation of numeracy skills."
In Advanced, the formula for variance which was in the Glossary has now been relocated in the body of the syllabus.
