Rating the books I read

Joy of Joy's Book Blog was featured on Book Blogger International last week.  One sentence made me update my rating system:  "Rather than rate books that I review, I think about the appeal of the book for different types of readers."  Here's what I added to my book rating guide last night:

Updated 3-24-14 to add one caveat:  These numbers from 2008 are all based on how much I personally enjoyed the book.  I can't judge for anyone else, so my ratings are completely subjective.  As a matter of fact, if I re-read a book, my opinion may very well change, based on what's going on in my life at that point.

Do you rate the books you read?  Do you have a rating system?

My NEW book rating guide

Updated 3-24-14 to add one caveat:  These numbers from 2008 are all based on how much I personally enjoyed the book.  I can't judge for anyone else, so my ratings are completely subjective.  As a matter of fact, if I re-read a book, my opinion may very well change, based on what's going on in my life at that point.

10 ~ Loved it!!  Couldn't put it down!!
9 ~ Excellent!
8 ~ Very Good
7 ~ Good
6 ~ Above Average
5 ~ Average
4 ~ Struggled to finish, but not worth it
3 ~ Annoying ~ a waste of time
2 ~ Poor ~ one I abandoned
1 - Pitiful!
0 ~ Awful!!  Don't bother

* DNF ~ Did Not Finish ~ discarded the book as a total waste of time

Updated 3-29-19:  For a few years I tried eliminating anything below five (5/10) by using "Nah" as a rating.  I tried "Not My Cuppa" (with "tea" implied) a few times.  Now I'm back to my original numbers because I just finished a book that needs that three (3/10) rating.
