I'm confused! I'm with Premier T and I have passed Level 3 so I rang up and ordered the necessary books for Level 4. Books have now been delivered along with my welcome pack which says I need to register with the AAT. This is where I'm confused. When I first started this course, I registered with the AAT and got my membership number. Do I not still use the same m'ship number now at Level 4? I assumed that all details would stay the same and I would just need to renew m'ship. Anyone clarify this for me?
