NCEA Resources

Leading up to exams, all my NCEA classes will find the following website useful:
http://www.nzqa.govt.nz/qualifications-standards/qualifications/ncea/subjects/
Click on the subjects you are doing, then go to your level, and click "Examination documents". This contains all of the past exams for this subject, and doing these is the best way to prepare yourself for this years exams.
