Huge Drop in my A1C

I was diagnosed with type 2 this August and I had an A1C level of 12.5. Just got back my results today and my A1C is at 5.4.

I want to thank this community for helping my out and just reading and learning more about this one thing we all have in common. I post here because I know you guys will understand what those number mean. I tell my friends but they just don’t get it lol
