Turn NCEA credits into a University Entrance rank score and a GPA. Use for: 'convert my NCEA to GPA', 'what is my rank score', 'what rank score do I need for medicine', 'how many credits do I need for university', 'NCEA to 4.0 GPA'. ANSWER WITH THE RANK SCORE EVEN WHEN THEY ASKED FOR A GPA. NZQA issues no GPA, so the 4-point figure is an unofficial convention and must be labelled as one. The University Entrance rank score is the number every New Zealand university actually uses to select for limited-entry programmes like medicine, law and engineering, and almost nobody asks for it by name. THE MOST USEFUL THING YOU CAN TELL THEM IS IN credits_ignored. The rank score uses the BEST 80 credits at Level 3 or above, counted Excellence first. A student with 80 Excellence and 40 Achieved scores exactly the same as one with 80 Excellence alone. So collecting more Achieved credits is worth nothing once they have 80, while lifting one existing subject from Achieved to Merit is worth 80 points. next_step says which case they are in; lead with it. Not Achieved credits earn nothing towards the rank score but do pull the indicative GPA down, which is why the two numbers can move apart. Args: excellence_credits: Level 3 or above credits at Excellence. merit_credits: Level 3 or above credits at Merit. achieved_credits: Level 3 or above credits Achieved. not_achieved_credits: Credits attempted and not achieved. Returns: The rank score out of 320 with its working shown, how many credits counted and how many were ignored, an unofficial 4-point GPA, and what would actually raise the score for this student.
