MMU Conditional offer

Hi I got a conditional offer from MMU. They asked me for NCEA Level 3 (80 credits) I’m a bit worried right now since not a lot of universities quite get the NCEA system. NCEA level 3 consists of 60 Level 3 credits and 20 level 2 credits to get a NCEA Level 3 Qualification.

One of the unis I applied gave me an offer but to their foundation course and the reason is that they thought I failed NCEA. I totally understand that it’s very complicated but I’m so worried MMU won’t get how NCEA really work since it’s my dream uni TT

*NCEA is New Zealand’s Education Qualification
