Getting to Achieved, Merit, and Excellence

NCEA's Achieved, Merit, and Excellence levels are based on a rubric called 'Solo Taxonomy.' For you to achieve, it's important to keep reflecting on where you are against this Solo Taxonomy.

  • Pre-Structural = Not Achieved

  • Uni Structural = Not Achieved / Developing

  • Multi Structural = Achieved

  • Relational = Merit

  • Extended Abstract = Excellence

Revision Options

Revision means you've learned the concepts already and are now just going back to them to examine your weakest areas so you can target the areas you need more practice on.

DO NOT revise if you have NOT yet learned the concepts in the first place. Go back and learn the concepts first.

1) Learn the 2.4 Vocabulary using Quizlet

Here's a Quizlet of all 2.4 Vocabulary

I've also created Quizlets for each sub-topics in the 2.4 standard.

Vocabulary for Cell Structure and Transport

Vocabulary for Enzymes

Vocabulary for Photosynthesis & Respiration

Vocabulary for Cell Cycle, DNA Replication and Mitosis

2) Go through the each of the concepts again. This should be done individually.

Last-Minutes Notes (No Brain Too Small)

You could read these Last Minute Notes by No Brain Too Small (to the left).

It is not fully comprehensive, but it outlines the absolute most important things to remember. Not sufficient for Merit or Excellence.
