Impact on Stage 6: Academic progress will determine placements in graded classes in Mathematics Standard, and Mathematics Advanced, as well as eligibility into the extension courses.

COURSE DESCRIPTION - MANDATORY

In Years 9 & 10, students are placed in one of three levels in graded classes. These are determined from a ranked list of all Year 8 students based on common tests completed throughout the year. The breakdown of the Stage 5 classes is detailed below:

• the top 25 students will be offered the opportunity to do the Accelerated Mathematics course,
• the next 60 students given the opportunity to study for the Advanced Mathematics 5.3 course,
• the next 150 students will study the Mathematics 5.2 course, and
• the remainder will study the Mathematics5.1 course.

Classes are subject to change throughout Years 9 & 10 based on performance. The level of Mathematics studied, and achievement gained will impact upon the Mathematics courses available for the HSC.
