The use of a Graphics Calculator was not essential but definitely assisted candidates in this assessment.

It is important that students show evidence (working) at all levels so that full or partial credit can be awarded, particularly when incorrect rounding has occurred or final answers have not been correctly presented for the context of the question.

Guess and check methods are not appropriate for demonstrating the required level of skills required.

The papers highlighted the need for students to be prepared in all areas of learning determined by the Achievement Standard as a lack of learning or understanding in one or more areas compromised the final result.

Candidates should write answers to a suitable degree of accuracy.

Lack of appropriate number and algebra skills often let candidates down. Candidates who were able to draw on mathematical skills at lower levels were at an advantage.

This goes through the techniques required for the Algebra unit.
