My grading seems to be off!!

Hello folks. I've been slacking lately on grading my records, and I apologise if I've not been on the money. I whipped out my goldmine book and put myself back to school again. I'm making a very diligent effort to not disappoint you ever again. Please do me a favor. Some of you great people have been at this a real long time. Please help me with your knowledge, so I can better serve my customers in the future. I love what I do, but I want to do it right. Thank's a great deal!!!
