High five sister! I've been taking one class at a time since January 2003! What's that, almost four years now?
Like you I was in no hurry and it hasn't been in my kids' best interest to have me gone fulltime at school just yet--lthough I am chomping at the bit now.
This approach was best for me and allowed me to get all A's and know the material inside out, backwards and forwards.
I'm concerned that my a&p is 3 years old now, but I also took it twenty years ago, so it's in my brain. And like I said, taking it slow allowed me to learn it rock solid. So I don't think memory will be a problem.
But if I don't get in this spring, I may go postal from waiting so long! If you hear a primal scream across the nation, that would be me getting postponed for some reason.
I have met others in my classes who are doing it this way for various reasons too.
Keep up the good work!
